World Meteorological Organization

Español

Regional Association IV (North America, Central America and the Caribbean) was established by the World Meteorological Congress, and extends from the Arctic to the tropics, which implies a great diversity of territories, ecosystems, climatic zones, cultures and languages. This Region is composed of 27 Members, including developed and developing States and Territories, Small Island Developing States and one Least Developed Country. Its supreme body meets at least every four years to outline the regional priorities and establish the corresponding work plans, considering the execution of the resolutions of Congress and the Executive Council in the Region, and the issuance of resolutions and decisions for the consideration of these two governing bodies.

Foreword by the President of the WMO Regional Association IV (RA IV)

Dear visitor,

Welcome to our redesigned and updated RA IV Community Platform.  After several months of hard work, this site is now ready to fulfil its purpose of keeping you informed about the work of our RA IV subsidiary bodies, as well as all RA IV activities and meetings.  This website will also help us to keep track of our progress with the RA IV Implementation Plan and the valuable contribution of the Chairs, Vice Chairs, other leaders and experts working in their different roles to serve our Members. 

A big “thank you” to everyone who has contributed to upgrading and maintaining this valuable information resource.  Let us all work together to keep it current.

Yours sincerely,           
Mr. Evan Thompson
