Dear Reader, 

         The Operational Newsletter was first introduced in 1982, at the request of the Commission for Basic Systems (CBS), with the objective of providing World Weather Watch Centres with urgent notifications and a summary of the latest operational information on the World Weather Watch and Marine Meteorological Services.  In December 2001 the CBS Management Group approved the electronic distribution of the Newsletter thus enabling operational centres to receive up-to-date information on a near real-time basis.

         This Newsletter is published at the end of each month and is disseminated free of charge through our on-line service.  Check our home page for the most recent issue, alternatively, complete the subscription form (if you havn’t already done so) and we will contact you when it is available.

         We hope that this Newsletter has been of service to you.  Should you feel that we did not meet with your requirements  please contact us.
