AnnexIII Summaryofthe2ndWGMAnnualMeetingESCAP/WMOTyphoonCommitteeSummary of the Second Annual Meeting of Working Group on Meteorology(WGM)

The second annualmeeting ofWorkingGroup onMeteorology (WGM)of theUnited

Nations Economic and Social Commission for Asia and the Pacific (ESCAP)/World

Meteorological Organization (WMO) Typhoon Committee was successfully held in

Tokyo,Japanbetweenon7-9October,2019.Hereisthesummaryofthemeeting:

1.IntroductionThe Typhoon Committee consists of working groups on meteorology (WGM),

hydrology (WGH), disaster risk and reduction (WGDRR), training and research

coordination(TRCG)andadvisory (AWG). Inorder tostrengthen thecommunication

amongMembers,prepareforcollaborationinannualpriorityplans,thesecondannual

WGM meeting was hosted by Japan Meteorological Agency (JMA), chaired by

chairperson Dr. Lei Xiaotu from China and vice-chairpersons Dr. Landrico Dalida, Jr.

from Philippines and Dr. Mohd Hisham bin Mohd Anip from Malaysia. Around 40

experts from11Members includingChina,HongKongChina, Japan,LaoPDR,Macao

China,Malaysia,Philippines,RepublicofKorea,Thailand,USAandVietNamattended

the meeting. The agenda and participant list can be found in Annex I and II,

respectively.

2.InvestigationofTCeventsAlthough tropical cyclone (TC) forecasts continue to improve in recent years, events

withlargeforecasterrors(trackand/orintensity)stillhappeneveryyear.Inaddition,

importance of social scientific perspectives is becomingmore andmore highlighted.

Therefore, themeeting invitedMembers to discuss TC events of difficult or extreme

cases, i.e., those with large forecast errors or caused significant �amages to the

Members, rare cases and TCs of Members’ interest. 9 TCs were included in the

discussion,namelyJELAWAT(1803),LANE,SOULIK(1819),JEBI(1821),MANGKHUT

(1822),YUTU(1826),PABUK(1901),WIPHA(1907)andLEKIMA(1909).Thecriteria

forTDstatusfordisturbanceswithinmonsoondepressions/gyreswerealsodiscussed.

ThemeetingencouragesforecastersandscientiststopaymoreattentiontoTCevents

website (https://severeweather.wmo.int/TCFW/), and to submit the article to TCRR

journal.

3.Recentimprovementsindata&productsharingandanalysistechniquesAtotalof9technicalpresentationswereheldinthemeetingonrecentprogressinTC

analysismethods, probability circles, best tracks, reconnaissance flights, use of dual

polarization radar in TC analysis, use of artificial intelligence in intensity forecast,

sea-surface AMV from Himawari-8/9, new satellite data or products from

GEO-KOMPSAT-2A and for products of RSMC Tokyo for Nowcasting. Collaborations

betweenMembersondatasharingwerealsodiscussedandencouraged.
