3.3.2 Terms of Reference for ET 3.3

Note that in the General Summary Text of the proceedings of the fourteenth session of the Commission for Climatology (3-10 November 2005, Beijing China) it is noted (item 11.2.6(g)) that the Terms of Reference are broad, long-term goals that constitute a framework to guide the work of the Expert Team (ET), and that each ET will set workplans with Specific, Measurable, Achievable, Realistic and Time-bound (SMART) goals consistent with that framework (see 4.3.3 below)


(a)     To complete, if necessary, the work of the ad hoc team (on El Niño Definitions and Indices) to finalize the catalogue of El Niño Definitions and Indices as used operationally by the different WMO Member States around the world, by major Global Producing Centres (GPCs), and by GPCs contributing to the WMO ENSO update;

(b)     To develop a strategy and common language for public communiqués, and recommend Guidelines for Members and relevant organizations to follow to improve collaboration on information and predictions of El Niño and La Niña;

(c)     To collaborate with the CCl ET on Research Needs, OPAG 2 ETs, WCRP CLIVAR WGSIP, the Global Producing Centres, research institutes including IRI, ECMWF, CIIFEN and other relevant institutions in their ongoing investigations of the potential for development of an internationally uniform approach to communication on the ENSO phenomenon;

(d)     To produce Guidelines on interoperability between the various definitions of El Niño and La Niña and their monitoring and impacts for the use in an early warning systems for drought management and flood protection and other climate-related hazards management;

(e)     To produce a Version 0 of an Atlas of regional ENSO impacts in map format by beginning to collect and assess regional ENSO impacts on various climate parameters and phenomena, to be used by decision and policy makers and its interaction with other atmospheric and oceanic phenomena (NAO, PDO, etc.);

(f)      To incorporate the WMO cross cutting themes (on Disaster Prevention and Mitigation, Space/GEO and Least Developed Countries) into planning and activities of the ET, and to collaborate as needed with experts (across all related disciplines) in other CCl ETs, in ETs of other WMO Technical Commissions, and in relevant external organizations;

(g)     To explore, document and make recommendations for addressing the needs for capacity building in each region, pertinent to this topic;

(h)     To submit reports in accordance with timetables established by the OPAG chair and/or Management Group.
