Warning dissemination using an existing platform and community automatic weather station ESCAP/WMO Typhoon Committee 5th integrated Workshop 6-10September 2010 Macao, China Hilda Lam Hong Kong Observatory Hong Kong, China

First project : real-time transmission of severe weather warnings using an existing platform

Background Project endorsed by 41st Typhoon Committee Session Using an existing internet web-based platform: –to make available local severe weather warnings issued by official weather services – to any interested individuals anywhere on the globe Warning dissemination by a ‘weather wizard’ facility developed by the Hong Kong Observatory

Weather Wizard – Simple installation

Dissemination of warnings using the ‘weather wizard’ function 1.User download a program and perform simple installation 2.user follow instruction to select user preferences 3.The program will retrieve latest warnings from the web server by regularly polling information from server 4.display warnings on a user PC

Weather Wizard - Warnings Warning logos will be displayed at the lower right- hand corner on the screen Dialog box will pop up with an audio alarm to alert users when there is a change of warning status Dialog box pop up automatically

Progress of warning dissemination project in 2009 At the 4th WGDPP meeting in April 2009,SWIC was recommended as the dissemination platform Agreement was later obtained from WMO PWS Expert Team for its use in this project

Severe Warning Information Centre (SWIC) ( All RSMC, TCWC and 12 TC members contribute warnings

Mechanism of how the warning dissemination works Participating Member : –decides the list of warnings to be made available –maintain the warnings in their web server using a standard format Hong Kong Observatory provides: –the standard format –the ‘weather wizard’ facility on SWIC Users: –go to SWIC and download a simple program to install on their PC –select warnings and set preference –receive the warnings (from participating member ) when they are in force.

Warning dissemination using SWIC

Latest development Hong Kong, China released a Development Guide for participating Members to provide warning information on their web server in January Macao, China and Guam made arrangement to maintain their warnings on the web server in accordance with the Development Guide The SWIdget was launched on the SWIC in July ( PC users anywhere may receive alerts of local warnings issued in Hong Kong, China; Macao, China; and Guam, USA.
