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

activitiessuchasuploadingdifficultorextremecasesdiscussedinthemeetingtoWMO
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.
4.Enhancedcooperationbetweenresearchandoperationalfields
Inordertoenhancethecooperationbetweenresearchandoperationalfields,topush
