WMO Climate Watch System

Chief World Climate Data and Monitoring WMO, Geneva [email protected]

Weather warning systems provide alerts on extreme weather occurring locally with a lead time of several hours to a week A natural evolution of meteorological alerts is to expand the time scale of the alerts to include information on climate conditions which can be expressed in terms of the departure from average climate conditions of the week, month or a season

(called climate anomalies)

and also to provide information on their persistence and evolution with time. Common Alerting Protocol (CAP) Implementation Workshop Geneva, Switzerland, 6-7 April 2011

Rational

Climate anomalies can occur over large geographical scale with a long lasting lifetime from a week to a season. This map shows a list of such extremes which occurred during 2009. Such extreme conditions can bring heavy and extended precipitations or extended episodes of deficits, heat waves, cold waves, etc. all having serious potential negative impacts on sectors

A climate Watch system including alerts

is therefore such system that enables providing

climate advisories

on the geographical extent, time frame and the magnitude and evolution of these anomalies  To enable improved Climate Risk Management 2 Common Alerting Protocol (CAP) Implementation Workshop Geneva, Switzerland, 6-7 April 2011

Implementation

-

Three founding principles

Global and Regional institutions ; e.g GPCs and RCCs provide inputs to CWS in terms of global and regional products/guidance; Met Services deliver outputs to the national users (advisories); - Interactions with the users is an essential element( for the planning and operational levels)

Need to bring a common understanding of these principles and promote a quick implementation in the regions:

 Regional workshops as a mechanism for enabling countries implement CWS 10 Common Alerting Protocol (CAP) Implementation Workshop Geneva, Switzerland, 6-7 April 2011
