                             JUNE HIGHLIGHTS
                             ---------------

  --> Rather quiet month--three tropical storms in North Pacific


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

     As was the case with May, no tropical cyclones nor significant
  tropical LOWs formed in the Southern Hemisphere during June.  The only
  named storms formed in the North Pacific Ocean--two in the west and
  one in the east.  Typhoon Linfa formed just after mid-month in the
  northern South China Sea and moved slowly northward, reaching a peak
  intensity of 75 kts per JTWC's analysis.  JMA's peak intensity for
  Linfa was 60 kts (10-min avg)--just under typhoon strength.  Linfa
  weakened prior to making landfall in Fujian Province, China.  According
  to the Wikipedia report, Linfa left 7 persons dead with 12 missing, 
  plus caused several hundred million dollars damage in the Philippines,
  Taiwan, and mainland China.

     During the final week of the month, Tropical Storm Nangka/Feria
  moved across the central Philippines and later made landfall in
  southern Guangdong Province, China.  Nangka/Feria remained a relatively
  weak tropical storm throughout its life.  JTWC's and JMA's peak MSW
  estimates were 45 kts and 40 kts, respectively.  The storm spawned a
  rare tornado in the Philippines, where scattered damage and six deaths
  were reported.  There were also 11 persons reported missing.

     In the Eastern North Pacific, Tropical Depression 01E formed on the
  18th a few hundred miles to the south-southeast of Cabo San Lucas.  The
  depression moved northward toward the coast, prompting the issuance of
  a tropical storm watch for portions of the Mexican mainland and a
  tropical storm warning for some offshore islands.  However, TD-01E
  weakened and dissipated very near the coast without reaching tropical 
  storm intensity.  A few days later Tropical Storm Andres formed about 
  175 nm south of Zihuatanejo, Mexico.  Andres was the latest-forming 
  initial tropical storm in the Eastern Pacific basin since Tropical 
  Storm Ava formed on July 3, 1969.  Andres moved northwestward near the 
  Mexican coastline and very briefly reached minimal hurricane intensity
  late on 23 June as it brushed the coast.   However, within 24 hours 
  after peaking in intensity, Andres had dissipated due to the effects 
  of cooler SSTs, drier air, and increased vertical shear.

     During the latter week of June a tropical depression formed in the
  eastern Arabian Sea and moved into the Gujarat region of India.  The
  system hovered in the coastal region, later moving back into the Arabian
  Sea, but subsequently dissipated without attaining cyclonic storm
  intensity.  According to the Wikipedia report, nine persons died due
  to strong lightning storms associated with the depression, and over
  100 mm of rain fell in Gujarat prior to landfall.

     In the North Atlantic basin, an interesting low-pressure area north
  of the Azores was numbered as an invest area (92L), and the system was
  referenced in TPC/NHC's Tropical Weather Outlooks.  The LOW exhibited
  a convective cloud pattern consistent with a subtropical storm, and
  SAB's Hebert/Poteat numbers reached ST3.0, suggesting winds of 45 kts.
  The system formed within the envelope of an upper-level cold LOW, and
  according to Jack Beven, was capped with a very large upper-level warm
  core.  This warm core was likely created by a suppressed tropopause
  and stratospheric air intrusion rather than warming due to convective
  heating, suggesting the system was not a tropical cyclone.  SSTs were
  near 15 C, while AMSU data indicated that 500-mb temperatures were
  around -20 to -24 C.  It is within the realm of possibility that this
  system might be reviewed for inclusion as a subtropical cyclone, but
  I tend to think it doubtful that this LOW will ever find its way into
  the Atlantic Best Tracks file.

             A REVIEW OF THE 2008-2009 TROPICAL CYCLONE SEASON

                        FOR THE SOUTHERN HEMISPHERE

     Following is a tabular summary of all the tropical depressions
  and tropical cyclones which occurred in the Southern Hemisphere
  between 1 July 2008 and 30 June 2009 as reported in the Monthly
  Global Tropical Cyclone Summaries prepared by the author.

    (1) Number - this is the sequential cyclone number assigned by JTWC
        in Hawaii.

    (2) Name - the name (if any) assigned by the responsible Tropical
        Cyclone Warning Centre.  For systems in the South Indian Ocean
        west of 90E and in the Southwest Pacific east of 160E which were
        unnamed, the alphanumeric designator applied by La Reunion or
        Fiji, respectively, is given in this column.

    (3) Dates - range of dates for which tracking information for the 
        cyclone is available in the Global Tropical Cyclone Tracks files
        prepared by the author.  The dates given in most cases refer to
        the time the system was in warning status and generally do not
        include the pre-depression stages of the disturbance.

    (4) Pressure - Lowest central pressure (either estimated or recorded)
        during the lifetime of the cyclone.  An asterisk (*) following
        the pressure indicates the reading was an actual measured
        pressure.   Central pressure is given in millibars, which is
        numerically equivalent to hectopascals.

    (5) MSW 1-min avg - maximum 1-minute average sustained windspeed in 
        knots as assigned by JTWC.  An asterisk (*) following the MSW
        indicates that it was an actual measured value.

    (6) MSW 10-min avg - maximum 10-minute average sustained windspeed
        in knots as assigned by the responsible Tropical Cyclone Warning
        Centre.  An asterisk (*) following the MSW indicates that it was
        an actual measured value.

    (7) Basins - tropical cyclone basins where the cyclone tracked during
        its life:

        SWI - Southwest Indian Ocean - West of 90E
        AUW - Northwest Australia/Southeast Indian Ocean - 90E to 135E
        AUE - Northeast Australia/Coral Sea - 135E to 160E
        SPA - South Pacific Ocean - East of 160E
        SAT - South Atlantic Ocean

     A number in parentheses (e.g. (1) ) following an entry refers to
  a note following the entries for the given basin.   A separate table
  is given for each of the four Southern Hemisphere basins.

     Abbreviations for Tropical Cyclone Warning Centres:

  JTWC -    Joint Typhoon Warning Center, formerly on Guam, now at
            Pearl Harbor, Hawaii
  MFR -     Meteo France Reunion (RSMC La Reunion)
  RSMC -    Regional Specialised Meteorological Centre

 NOTES:

 (1) During a post-storm analysis, it was determined that Gabrielle had
     not met Australia's requirements for a tropical cyclone.  Gales did
     occur in one quadrant or another at a time, but to qualify as a
     tropical cyclone, gales must occur in at least two quadrants
     simultaneously for at least six hours.

 NOTES:

 (1) Ingham (WMO 32078, 18.65S/146.18E, Alt. 11.8m) reported a 10-min
     mean wind of 43 kts at 31/1700 UTC.

 (2) While within Brisbane's AOR, this system was more tropical in nature
     and had some associated gales.  After moving into Nadi's AOR, the
     LOW took on a more hybrid character.

 (3) According to Derrick Herndon, on 23 April the AMSU intensity
     algorithm suggested a CP of 970 mb and winds of 70 kts.  He also
     noted that QuikScat imagery on the same date indicated wind flags
     of 60 kts.  The LOW at this time sported a large eye-like feature,
     and since it appeared to be warm core and driven by convective
     instead of baroclinic processes, it may possibly have been a
     tropical cyclone.

 (2) System was a subtropical LOW.  SAB rendered a Hebert/Poteat number
     of ST3.0 on 16 April.  The CP value is based upon NCEP reanalysis
     data.

Note: A special thanks to Steve Young for producing and sending the above
track.  Portions of the track through 31 May 1800 UTC and from 03 June
1800 UTC were generated using GRADS software with the NCEP re-analysis.
Data points from 01 June 0000 UTC through 03 June 1200 UTC are based upon
NRL data files.  Satellite classifications using the Hebert/Poteat method
for subtropical systems were obtained from SAB satellite bulletins.
This system was not a tropical cyclone, but did display some satellite
characteristics of a subtropical cyclone.  TPC/NHC currently considers
the LOW to have been non-tropical--it remains to be seen if it might
possibly be considered for reclassification as a subtropical cyclone.

                          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.

Note: JMA classified this disturbance as a minor tropical depression at
14/0600 UTC but downgraded it to a low-pressure area 18 hours later.  A
new LOW center formed on 16 June about 400 nm west of the old center,
which was still being followed.  The Wikipedia report treats the two as
one system; however, JMA continued to report the old center in their
high seas bulletins for another 24 hours or so after the new center had
been identified in the South China Sea.  My inclination was to treat the
system as two separate disturbances, but in order to be consistent with
the Wikipedia report, I have compiled just one track, indicating in the
Remarks column at which point the new center developed.

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.

                  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/
