               GLOBAL TROPICAL CYCLONE TRACKS - JULY 2009

          !!!! IMPORTANT -- PLEASE SEE NOTE AT END OF FILE !!!!


                             JULY HIGHLIGHTS
                             ---------------

  --> Another rather quiet month--a few tropical storms, including one
      hurricane and one typhoon in North Pacific


                             GLOBAL OVERVIEW
                             ---------------

     As was the case with June, no tropical cyclones nor significant
  tropical LOWs formed in the Southern Hemisphere during July.  The only
  named storms formed in the North Pacific Ocean--two in the west and
  four in the east.  Tropical Storms Blanca and Dolores in the Eastern
  North Pacific were similar, each forming a few hundred miles to the 
  south-southwest of Baja California and following northwesterly 
  trajectories into cooler waters and stable air.  Both attained peak 
  estimated intensities of 45 kts.  Hurricane Carlos formed on 10 July
  very deep in the tropics near 10N/111W.  Carlos moved westward at a low
  latitude, never departing from the 10th parallel by more than half a
  degree.  The storm intensified into a 75-kt hurricane on 12 July before
  somewhat mysteriously weakening to 45 kts on the 13th.  However, Carlos
  recovered and reached a peak intensity of 90 kts on 15 July.

     Late in the month, Tropical Depression 06E formed just east of 140W
  and moved westward into Honolulu's AOR, becoming Tropical Storm Lana
  on 30 July.  Lana followed a fairly straight westerly track which took
  it well south of Hawaii, reaching a peak intensity of 55 kts late on
  31 July before gradually weakening.  According to the Wikipedia page
  for the 2009 Eastern Pacific season, Lana is only the fourth Central
  Pacific tropical cyclone since at least the early 1980s which initially
  formed as an Eastern Pacific tropical depression.  The others were
  Tropical Storm Lala (TD-14E of 1984), Hurricane Iniki (TD-18E of 1992),
  and Hurricane Li (TD-08E of 1994).

     Three tropical cyclones developed in the Northwest Pacific basin
  during July: one tropical depression, one tropical storm, and one
  typhoon.  The typhoon, Molave, was classified as a typhoon for only
  one six-hour period by both JMA and JTWC.  Thus, the month of July was
  almost typhoon-less in the WestPac, something which hasn't happened since
  1998.  July of 1999 almost completely went by without a typhoon--Tropical
  Storm Olga was upgraded to typhoon status on the final day of the month.

     Tropical Storm Soudelor/Gorio pursued a straight west-northwesterly 
  track from a position several hundred miles northwest of Yap across the 
  northern tip of Luzon, Hainan Dao, and the Gulf of Tonkin before moving
  into southern China.  Soudelor was a minimal tropical storm which existed
  in a sheared environment and was never able to generate sustained deep
  convection around the LLCC.  However, it was a prolific rainmaker, 
  producing upwards of 130 mm of rain in northern Luzon which resulted in 
  flash flooding and landslides.  In the Philippines almost 20,000 people 
  were affected by the flooding and one person was killed with ten villages
  being flooded by the storm.  In China, torrential rains in Hainan caused
  significant flooding that drowned 15 hikers and left several others 
  missing.  Many roads were destroyed or cut off by landslides and 
  30 villages were inundated.  In Vietnam, the storm also was responsible 
  for torrential rains with 250 mm being recorded in northern Vietnam and 
  130 mm in the city of Hanoi.  Three persons were killed and thousands of
  hectares of cropland were inundated.

     Tropical Depression 06W formed on 11 July several hundred miles east
  of the northern Philippines and moved on a northwesterly track which
  carried it across southern Taiwan and into mainland China.  PAGASA named
  the system Huaning and upgraded it to tropical storm status on the 13th.
  However, JMA and JTWC both treated the system as a 30-kt tropical
  depression.

     Tropical Storm Molave (named Isang by PAGASA) formed several hundred
  miles east of Mindanao around mid-July.  After moving initially westward,
  the storm embarked on a northwesterly track east of the Philippines which
  carried it to the Luzon Strait.  The storm turned to a west-northwesterly
  heading and intensified, reaching typhoon status shortly before making
  landfall in southern China near Hong Kong.  As noted above, both JMA and
  JTWC classified Molave as a minimal typhoon for only a six-hour period
  shortly before landfall.  The Hong Kong Observatory also classified
  Molave as a typhoon. According to the Wikipedia report, Molave/Isang
  was responsible for four deaths.

     In the North Indian Ocean basin, one system developed which was
  classified as a deep depression by IMD.  The system formed early on
  20 July in the northern reaches of the Bay of Bengal.  The depression
  intensified into a deep depression during the day and moved west-
  northwestward, moving inland during the evening between Balasore and
  Digha.   Maximum winds (3-min avg) were estimated at 30 kts.

             !!!!!!!!!!!!!!!!! EXTRA FEATURE !!!!!!!!!!!!!!!!!

               REVIEW OF GLOBAL TROPICAL CYCLONE TERMINOLOGY
            

     This extra feature is something which I've included on several
  occasions, the last being in the April, 2005, summary.  I have updated
  a few items based upon changes in basic definitions.

     The following is a synopsis of the operational terminology used by
  the various TCWCs to describe the different stages of tropical cyclone
  development and intensification.   This gives the formal terminology
  used to refer to a given cyclone in warnings, public advices, and
  discussion bulletins.  The adjective "severe" is used in several regions
  with quite different meanings, and these are defined below if the term
  is formally applied to designate an intensity range.  In the U. S., the
  term may be frequently used to describe the character of a hurricane,
  but is not formally used as the descriptor for a given cyclone intensity
  range.

     In the Atlantic and Northeast Pacific basins, the Saffir/Simpson
  Hurricane Wind Scale is utilized to further classify tropical cyclones
  with winds exceeding hurricane intensity.  This is the same as the older
  Saffir/Simpson Scale but with the central pressure and storm surge
  descriptors removed.  Information on the scale may be found at the
  following URL:

  http://www.nhc.noaa.gov/aboutsshs.shtml>

     The TCWCs in Australia and Fiji also employ a five-category scale to
  further classify all tropical cyclones above gale force.  The Australian
  Cyclone Severity Scale is based upon the peak gusts expected to occur
  within a cyclone.  Information on this scale may be found at:

  http://www.bom.gov.au/weather/cyclone/about/about-tropical-cyclones.shtml#severity>


  1.  ATLANTIC and NORTHEAST PACIFIC Basins - TPC/NHC (also CPHC)
      MSW Averaging Period: 1 minute

      Tropical Cyclone - generic term for systems of all intensities
      Tropical Disturbance - distinct area of disturbed weather but
         usually with no well-defined low-level circulation apparent/
         regular advisories not issued/ usually corresponds to Dvorak
         ratings less than T2.0
      Tropical Depression - fairly well-defined low-level circulation/
         MSW less than 34 kts/ Dvorak rating usually T2.0
      Tropical Storm - MSW in range of 34-63 kts/ Dvorak rating T2.5,
         T3.0, or T3.5
      Hurricane - MSW exceeding 63 kts/ Dvorak rating T4.0 or higher

     The point at which regular advisories are initiated is a little
  subjective.  A system with a Dvorak rating of T1.5 might be upgraded
  to a tropical depression if it were in a position to affect a populated
  area and/or if it seemed to be rapidly intensifying and its development
  potential was considered excellent.

    
  2.  JTWC for NORTHWEST PACIFIC Basin Only
      MSW Averaging Period: 1 minute

      Tropical Cyclone - generic term for systems of all intensities
      Tropical Disturbance - distinct area of disturbed weather but
         usually with no well-defined low-level circulation apparent/
         regular advisories not issued/ usually corresponds to Dvorak
         ratings of T1.0 or less/ MSW generally less than 25 kts
      Tropical Depression - fairly well-defined low-level circulation/
         MSW 25-34 kts/ Dvorak rating usually T1.5 - T2.0
      Tropical Storm - MSW in range of 34-63 kts/ Dvorak rating T2.5,
         T3.0, or T3.5
      Typhoon - MSW exceeding 63 kts/ Dvorak rating T4.0 or higher
      Super typhoon - MSW reaching or exceeding 130 kts


  3.  JTWC for NORTH INDIAN OCEAN and SOUTHERN HEMISPHERE
      MSW Averaging Period: 1 minute

     For the North Indian Ocean and all Southern Hemisphere regions, JTWC
  uses only the generic term "Tropical Cyclone" to refer to systems of all
  intensities in warning status.   Warnings are usually initiated when the
  system is forecast to produce gale/tropical storm force winds within
  48 hours.  In many cases winds are already approaching this threshold
  when the first warning is issued and frequently the initial MSW is set
  at 35 kts.


  4.  NORTHWEST PACIFIC Basin - JMA (Japan) 
      MSW Averaging Period: 10 minutes

      Tropical Cyclone - generic term for systems of all intensities
      Low-pressure Area - distinct area of disturbed weather but
         usually with no well-defined low-level circulation apparent/
         regular warnings not issued
      Tropical Depression - fairly well-defined low-level circulation/
         MSW less than 34 kts
      Tropical Storm - MSW in range of 34-47 kts/ Dvorak rating T2.5
         or T3.0
      Severe Tropical Storm - MSW in range of 48-63 kts/ Dvorak rating
         T3.5 or T4.0
      Typhoon - MSW exceeding 63 kts/ Dvorak rating T4.5 or higher

     The Japanese Meteorological Agency (JMA) is the World Meteorological
  Organization's (WMO) official Regional Specialised Meteorological
  Centre (RSMC) for the Northwest Pacific Basin.   While adhering to
  a 10-min averaging period for MSW, JMA normally equates 34 kts to a
  Dvorak rating of T2.5; thus, JMA and JTWC agree in principle on the
  threshold of tropical storm intensity.   However, for very intense
  typhoons, JMA's MSW estimates are usually far below those assigned
  by JTWC due to a much lower 1-min to 10-min conversion factor for
  extreme intensities.  

     The meteorological services of other Asian nations issue tropical 
  cyclone warnings for portions of the Northwest Pacific region,
  including the Philippines, Hong Kong, China, Vietnam, Taiwan, and
  Korea.   Warnings from these weather services are issued independently
  of JMA but utilize the same terminology and are usually reasonably
  close to JMA's positions and intensity estimates.


  5.  NORTH INDIAN OCEAN Basin - IMD (Indian Meteorological Department)
      MSW Averaging Period: 3 minutes

      Zone of disturbed weather - a zone in which the pressure is low
         relative to the surrounding region and there are convective
         cloud masses which are not organized
      Low-pressure Area - an area enclosed by a closed isobar with mean
         surface winds less than 17 kts
      Depression - well-defined low-level circulation but with MSW
         generally less than 28 kts/ Dvorak rating of T1.5
      Deep Depression - depression with MSW in range of 28-33 kts/ 
         Dvorak rating of T2.0
      Cyclonic Storm - tropical cyclone with MSW in range of 34-47 kts/
         Dvorak rating T2.5 - T3.0
      Severe Cyclonic Storm - tropical cyclone with MSW in range of
         48 - 63 kts/ Dvorak rating of T3.5
      Very Severe Cyclonic Storm - tropical cyclone with MSW in the range
         of 63 kts - 119 kts/ Dvorak rating T4.0 or higher
      Super Cyclonic Storm - tropical cyclone with MSW 120 kts or higher
      
     The Indian Meteorological Department (IMD) is the WMO's RSMC for
  the North Indian Ocean (Bay of Bengal and Arabian Sea), although the
  meteorological services of other nations may also issue warnings for
  portions of the basin.   The MSW values reported in warnings are
  considered to be over a 3-min averaging period; however, IMD does not
  modify the Dvorak scale.


  6.  SOUTHWEST INDIAN OCEAN Basin (West of 90E)
      MSW Averaging Period: 10 minutes

      Zone of Disturbed Weather - term used to describe weak, ill-defined
         systems with winds generally less than 25 kts and corresponding
         to Dvorak ratings of less than T2.0
      Tropical Disturbance - MSW usually 25 kts near center/ Dvorak
         rating usually T2.0 (Beaufort Force 6) / such systems usually
         classified as tropical depressions by most TCWCs
      Tropical Depression - MSW in range of 28-33 kts (Beaufort Force 7 -
         Dvorak T2.5)
      Moderate Tropical Storm - MSW in range of 34-47 kts/ Dvorak rating
         of T3.0 - weak T3.5
      Severe Tropical Storm - MSW in range of 48-63 kts/ Dvorak rating
         of strong T3.5 - T4.0
      Tropical Cyclone - MSW in range of 64-89 kts/ Dvorak rating of
         T4.5 - T5.5
      Intense Tropical Cyclone - MSW in range of 90-115 kts/ Dvorak
         rating T6.0 - T6.5
      Very Intense Tropical Cyclone - MSW exceeding 115 kts/ Dvorak
         rating T7.0 - T8.0

     The WMO's RSMC for the South Indian region is Meteo France on the 
  French island of La Reunion; however, names are actually assigned by the
  Sub-regional Tropical Cyclone Advisory Centres on Mauritius (east of 55E)
  and Madagascar (west of 55E).   The La Reunion TCWC employs a conversion
  factor of 0.88 to convert the 1-minute MSW Dvorak scale to an equivalent
  10-minute average scale.  (Prior to the 1999-2000 season, the conversion
  factor used was 0.80.)


  7.  AUSTRALIAN REGION (longitude 90E eastward to longitude 160E)
      MSW Averaging Period: 10 minutes

      Tropical LOW - term is used to describe disturbances ranging from
         diffuse, ill-defined low-pressure areas all the way to well-
         organized tropical depressions with MSW up to 33 kts
      Tropical Cyclone - MSW in range of 34-63 kts/ Dvorak rating ranging
         from a strong T2.5/weak T3.0 to T4.0
      Severe Tropical Cyclone - MSW exceeding 63 kts/ Dvorak T4.5 or
         higher

     Warnings in the Australian Region are issued by three separate TCWCs
  at Brisbane (Queensland), Perth (Western Australia), and Darwin
  (Northern Territory) with Darwin being the RSMC for the region.  In
  addition to these, a TCWC at Port Moresby, Papua New Guinea (formerly
  an Australian territory) issues warnings for a small portion of the
  region near and east of the island of New Guinea, and a TCWC at Jakarta,
  Indonesia, issues warnings for the region west of 125E and north of
  10S.   The Papua New Guinea and Indonesian regions have an extremely low
  incidence of tropical cyclone occurrences.   

     The Australian centres avoid use of the term "tropical depression" in
  public advices primarily to reduce possible confusion with the use of 
  the term "depression" in association with extratropical systems; and 
  also possibly because until recently (early 1990's), in the Southwest 
  Indian Ocean Basin, a "tropical depression" meant any system with winds 
  up to 63 kts (hurricane force).     The Australian TCWCs utilize a 
  conversion factor of 0.88 or 0.90 to modify the 1-minute Dvorak scale to
  an equivalent 10-minute average scale.

     In the Australian Region to qualify as a tropical cyclone a tropical
  LOW must be accompanied by gales surrounding more than 50% of the center
  of circulation for a period of at least six hours.   In order to insure
  that adequate warnings are provided, it is not at all unusual for a
  system to be named as a tropical cyclone, but later reduced to tropical
  LOW status after a careful post-storm analysis reveals that this spatial
  distribution of gales criterion was not met, e.g., Isobel and Odette,
  2007, and Gabrielle, 2009.


  8.  SOUTH PACIFIC Basin (east of longitude 160E)
      MSW Averaging Period: 10 minutes

      Tropical Disturbance - distinct area of disturbed weather but
         usually with no well-defined low-level circulation apparent/
         regular advisories not issued/ usually corresponds to Dvorak
         ratings less than T2.0
      Tropical Depression - fairly well-defined low-level circulation/
         MSW less than 34 kts/ Dvorak rating usually T2.0 or weak T2.5
      Tropical Cyclone - MSW exceeding 33 kts/ Dvorak rating of
         strong T2.5/T3.0 to T4.0
      Severe Tropical Cyclone - MSW exceeding 63 kts/ Dvorak T4.5 or
         higher

     The TCWC at Nadi, Fiji, is the RSMC for the South Pacific basin
  but the meteorological service of New Zealand (Wellington) issues
  warnings for systems that move (or very rarely form) south of latitude
  25S.    The Fiji TCWC employs a 1-minute to 10-minute MSW conversion
  factor of 0.90 when adjusting the Dvorak scale.

     A tropical system can have associated gales and still be classified
  as a tropical depression if the gales are well-removed from the center.
  In such cases the gales are usually found in only one or two quadrants. 
  Prior to 2000, the WMO Region V definition of a tropical cyclone required
  that gales surround the center, but the definition was changed to allow 
  classification as a tropical cyclone if gales were present near the 
  center and likely to persist, even if in only one quadrant.

                        ----------------------

     The track coordinates, central pressure and 1-minute average
  maximum sustained wind values were obtained from the operational
  forecast/advisories issued by the Tropical Prediction Center/National
  Hurricane Center in Miami, Florida, for locations east of longitude
  140W, and from the Central Pacific Hurricane Center in Honolulu,
  Hawaii, for locations west of longitude 140W.  A 1-minute averaging
  period is the standard used by all U. S. civilian and military
  warning services for tropical cyclone warnings.

NORTHWEST PACIFIC (NWP) - North Pacific Ocean West of Longitude 180


                          Sources of Information
                          ----------------------

     The track coordinates and 1-minute average maximum sustained wind
  values in general were taken from operational warnings issued by the
  Joint Typhoon Warning Center (JTWC) of the U. S. Air Force and Navy,
  located at Pearl Harbor, Hawaii.  The central pressure and 10-minute
  average maximum sustained wind estimates for most systems were obtained
  from warnings issued by the Japanese Meteorological Agency (JMA), which
  is the World Meteorological Organization's Regional Specialised Meteor-
  ological Centre for the basin.  In a few instances, information from
  warnings issued by other Asian warning centers may have been utilized.
  The center position coordinates from JMA and other centers were com-
  pared with those from JTWC and annotations made in the Remarks column
  when the differences in general amounted to 40-50 nm or more.

     Michael V. Padua of Naga City in the Philippines, owner of the
  Typhoon 2000 website, sends me cyclone tracks based upon warnings
  issued by the Japanese Meteorological Agency and the Philippines'
  Atmospheric, Geophysical & Astronomical Services Administration
  (PAGASA).  A special thanks to Michael for his efforts.

NORTH INDIAN OCEAN (NIO) - Bay of Bengal and Arabian Sea


                         Sources of Information
                         ----------------------

     The track coordinates and 1-minute average maximum sustained wind
  values in general were taken from operational warnings issued by the
  Joint Typhoon Warning Center (JTWC) of the U. S. Air Force and Navy,
  located at Pearl Harbor, Hawaii.   Occasionally some information may
  have been gleaned from the daily tropical weather outlooks and other
  bulletins issued by the Indian Meteorological Department (IMD), which
  is the World Meteorological Organization's Regional Specialised Meteor-
  ological Centre for the basin.
 
     The reported maximum sustained winds are based on a 1-minute
  averaging period, which is used by all U. S. civilian and military
  weather services for tropical cyclone warnings.     For synoptic
  observations in the North Indian Ocean region, both 10-minute and
  3-minute average winds are employed, but IMD makes no attempt to
  modify the Dvorak scale for estimating tropical cyclone intensity;
  hence, a 1-minute average MSW is implied.

  SPECIAL NOTE!!!  I have changed the header in the second MSW column
  to reflect a 3-min avg MSW.  This is what the India Meteorological
  Department uses as their standard.  They do not modify the Dvorak
  scale, but consider the reported MSW to be a 3-min avg.  The 
  difference between a true 1-min avg MSW and 3-min avg MSW would be
  expected to be essentially negligible.  I made this change in order
  to have a column available to report IMD's intensity estimates, out
  of consideration for the fact that the office is the WMO's official
  RSMC for the North Indian Ocean basin.  For the Northwest Pacific
  basin and the entire Southern Hemisphere, the 10-min avg MSW column
  provides a place to report the RSMC's intensity estimate for comparison
  purposes with JTWC's 1-min avg MSW.

  Indian Ocean Cyclone Season:

                  SOURCES OF TROPICAL CYCLONE INFORMATION

     The purpose of this section is to list some websites where many and
  varied types of tropical cyclone information are archived.  Many readers
  will know about these already, but for the benefit of those who don't,
  I wanted to include them. 

  (1) Aircraft Reconnaissance Information
  ---------------------------------------

     Various types of messages from reconnaissance aircraft may be
  retrieved from the following FTP site:

     ftp://ftp.nhc.noaa.gov/pub/products/nhc/recon/>

     Information regarding how to interpret the coded reconnaissance
  messages may be found at the following URL:

     http://www.nhc.noaa.gov/reconlist.shtml>

  Links are also included to websites with further information about the
  U. S. Air Force 53rd Weather Reconnaissance Squadron and the NOAA Air-
  craft Operations Center.

  (2) Archived Advisories
  -----------------------

     All the advisory products (public advisories, forecast/advisories,
  strike probabilities, discussions, various graphics) issued by TPC/NHC
  are archived on TPC's website.  For the current year (using 2004 as an
  example), the archived products can be found at:

     http://www.nhc.noaa.gov/archive/2004/index.shtml>

  Links to tropical products archives for earlier years are available at
  the following URL:

     http://www.nhc.noaa.gov/pastall.shtml>

  JTWC warnings for past storms are archived on the NRL Monterrey website:

     http://www.nrlmry.navy.mil/tc_pages/tc_home.html>

  On the NRL site, the link to past years can be found in the upper left 
  corner of the screen.

     I am not aware at the moment of any other TCWC which archives all
  its tropical cyclone warning/advisory products for public access, but
  if I learn of any, I will add them to this list.

  (3) Satellite Imagery
  ---------------------

     Satellite images of tropical cyclones in various sensor bands are
  available on the NRL Monterrey and University of Wisconsin websites,
  courtesy of Jeff Hawkins and Chris Velden and their associates.  The
  links are:

     http://www.nrlmry.navy.mil/tc_pages/tc_home.html>

     http://cimss.ssec.wisc.edu/tropic/tropic.html>

  On the NRL site, the link to past years can be found in the upper left 
  corner of the screen.  For the CIMSS site, a link to data archives is 
  located in the lower left portion of the screen.

     Additional tropical satellite imagery, along with looping ability for
  composite microwave imagery for the Western Hemisphere north of the
  equator, can be found at:

  (1) For the Eastern North Pacific:

     http://www.ssd.noaa.gov/PS/TROP/trop-epac.html>

  (2) For the Atlantic, Gulf of Mexico and Caribbean Sea:

     http://www.ssd.noaa.gov/PS/TROP/trop-atl.html>

  (4) Cyclone Tracking Information
  --------------------------------

     There is a U. S. Navy site that tracks tropical cyclones at 6-hourly
  intervals which often includes pre and post-advisory positions.  The
  link to the site is:

  http://www.nrlmry.navy.mil/atcf_web/doc_archives/>

     Steve Young has compiled many of these tracks onto a single webpage
  which is very user-friendly:

  http://home.earthlink.net/~shy9/tc1.htm>

*************************************************************************
*************************************************************************

              !!!!!!  IMPORTANT NOTE - PLEASE READ  !!!!!!

     To repeat the caveat which is included in the Author's Note
  at the end of the cyclone summaries--the tropical cyclone tracks
  I prepare are based upon the operational warnings/advisories/
  advices/bulletins which are issued by the various tropical cyclone
  warning agencies around the world.   Users of these tracks should
  be aware that they are preliminary and subject to revision during
  post-seasonal analyses of the cyclones by the forecasters and
  analysts at the several warning centers.

     For the Atlantic and Northeast Pacific basins, official tropical
  cyclone reports and "best tracks" can be found at the website of
  the Tropical Prediction Center/National Hurricane Center:

     http://www.nhc.noaa.gov>

     The Joint Typhoon Warning Center's website contains links to their
  Annual Tropical Cyclone Reports which include that agency's "best
  tracks" for tropical cyclones in the Northwest Pacific basin, the
  North Indian Ocean, and the Southern Hemisphere:

     https://metocph.nmci.navy.mil/jtwc.php>


  SPECIAL NOTE:  Back issues of the global tropical cyclone summaries
  and monthly cyclone track files can be obtained at the following
  websites:

    ftp://ftp.aoml.noaa.gov/hrd/pub/landsea/padgett/>
