GLOBAL TROPICAL CYCLONE TRACKS - MARCH 2000 NORTH INDIAN OCEAN (NIO) - Bay of Bengal and Arabian Sea NOTE: The tracking and intensity information for North Indian Ocean Basin tropical cyclones is based upon operational warnings from the Joint Typhoon Warning Center of the U.S. Air Force and Navy at Pearl Harbor, Hawaii. The MSW are based on a 1-min averaging period, which is used by all U.S. civilian and military weather services for tropical cyclone warnings. Some information was also obtained from the Indian Meteorological Department (IMD). JTWC issued no warnings on the system tracked below, but two Formation Alerts were issued on successive days for the area of disturbed weather (29 and 30 Mar) with the Alert being cancelled on 31 Mar. ************************************************************************* Storm Name: Trop.

IMD on 30 March referred to the system as a cyclonic storm (i.e., tropical storm), but since JTWC never initiated warnings, I have chosen to refer to the system as a tropical depression. ************************************************************************* NOTE: Following is an alternate track for the above system provided by Roger Edson of the University of Guam. A special thanks to Roger for his analyis of this interesting system. In accordance with a practice I initiated last summer, I have designated the storm with the Greek letter "Iota" since it was an unnumbered/unnamed system likely of tropical storm intensity in its latter stages.

He used available scatterometer data and TRMM, infrared and visible imagery (but not a complete set). Positions are to the nearest 0.5 degrees. Some of the MSW values were obtained with the fairly new QuikScat scatterometer and Roger adds that this is not a "proven" sensor yet--it could have a high or low bias. ************************************************************************* ************************************************************************* SOUTH INDIAN OCEAN (SIO) - South Indian Ocean West of Longitude 90E NOTE: The tracking coordinates, 10-min avg MSW, and estimates of central pressure were obtained from the RSMC La Reunion's advisories, while the 1-min avg MSW were taken from JTWC's warnings. A special thanks is due to Patrick Hoareau of Rennes, France, (and a former resident of La Reunion) for preparing the track for Intense Tropical Cyclone Hudah. ************************************************************************* Storm Name: Trop.

JTWC warnings were utilized for making comparisons and for supplying information for times when the Australian warnings were unavailable. The 10-min MSW values were obtained from the Australian warnings while the 1-min MSW values were assigned by JTWC. The tropical cyclone warnings from Perth report the analyzed cyclone positions at 0400, 1000, 1600, and 2200 UTC instead of the more familiar 0000, 0600, 1200, and 1800 UTC utilized by most TC warning agencies.

Warnings from JTWC (west of 180) and from NPMOC (east of 180) were utilized for the purpose of making comparisons and for supplying information for times when the Nadi or Wellington warnings were unavailable. The 10-min avg MSW values were taken from the Fiji or New Zealand warnings while the 1-min avg MSW values were obtained from the JTWC or NPMOC warnings. A special thanks to Alipate Waqaicelua, Chief Forecaster at the Nadi, Fiji, TCWC for sending me summaries and tabulated tracks for Tropical Cyclones Leo and Mona. ************************************************************************* Storm Name: LEO (14F) Cyclone Number: 18P Basin: SWP Date Time Lat Lon Cent MSW MSW Remarks (GMT) Press 1-min 10-min (mb) (kts) (kts) ------------------------------------------------------------------------- 00 MAR 05 0000 20.3 S 153.8 W 1002 20 See Note 00 MAR 05 0600 20.6 S 154.8 W 1002 20 00 MAR 05 1200 21.7 S 157.3 W 1000 25 00 MAR 05 1800 22.0 S 158.5 W 1000 25 00 MAR 06 0000 22.7 S 160.2 W 1000 25 00 MAR 06 0600 24.0 S 161.7 W 997 30 00 MAR 06 1200 24.5 S 163.2 W 995 35 00 MAR 06 1800 25.3 S 164.8 W 990 40 Entered Wellington AOR 00 MAR 07 0000 27.5 S 165.2 W 985 50 00 MAR 07 0600 29.5 S 166.0 W 985 50 00 MAR 07 1200 31.1 S 167.0 W 985 50 00 MAR 07 1800 32.7 S 166.7 W 987 50 00 MAR 08 0000 36.0 S 166.0 W 992 45 Extratropical 00 MAR 08 0500 40.0 S 165.0 W 992 40 00 MAR 08 1100 41.0 S 164.0 W 996 40 00 MAR 08 1700 44.0 S 159.0 W 997 40 00 MAR 09 0500 49.0 S 153.0 W 973 40 Note: There are no 1-min MSW estimates for Tropical Cyclone Leo because I received only one warning (#2) from NPMOC.
