Regional Association IV – Hurricane Operational Plan for North America, Central America and the Caribbean (WMO-No. 1163)
The regional activities under the WMO Tropical Cyclone Programme consist mainly of the programmes pursued by groups of countries acting in concert to improve their warning systems. In Region IV (North America, Central America and the Caribbean) there is a long history of collective action specifically designed to protect people and property from the severe tropical cyclones which are called hurricanes in the Region. A working group, known as the RA IV Hurricane Committee, was established by the seventh session of Regional Association IV (Mexico City, April May 1977) to promote such activities within the framework of the Tropical Cyclone Programme (Tropical Cyclone Project until Eighth Congress, 1979).
As requested by the RA IV Hurricane Committee, the RA IV Hurricane Operational Plan has been made available to all concerned through this document. New editions and supplements will be issued from time to time in the years ahead to reflect further development, updating and other changes to the plan.

Climatology briefly discusses jets streams, distribution of synoptic features, storm tracks of tropical and extratropical cyclones, the fronts, and sensible weather associated with the Northeast and Southwest Monsoons.PermalinkContains: Inter-annual Variation of Frequency of Cyclonic Disturbances Landfalling over WMO/ESCAP Panel Member Countries; Toward Improved Projection of the Future Tropical Cyclone Changes; An Assessment of Climate Change Impact on Cyclone Frequency and Design Wave Height in the Oman Sea; Long-Range Prediction of Tropical Cyclones for Bangladesh; On Developing a Tropical Cyclone Archive and Climatology for the South Indian and South Pacific Oceans; International Best Track Archive for Climate Stewardship (IBTrACS): Synthesizing Global Tropical Cyclone Best Track Data; Simulation of Track and In ...PermalinkPermalinkSevere calamities and fatalities have arisen from landfalling tropical cyclones (TC) around the world in recent years, such as Morakot (August 2009) in western North Pacific, Nargis (May 2008) in Bay of Bengal, Gonu (June 2007) in North Arabian Sea, Bilis (July 2006) in western North Pacific, Katrina (August 2005) in Gulf of Mexico, and Catarina (March 2004) in South Atlantic etc. Transferring the advancements from the research community to operational forecast centers in NMHSs would be helpful for improving the landfalling tropical cyclone (LTC) forecasts and for mitigation of high-impact tro ...PermalinkWMO, 2010PermalinkWorld Meteorological Organization (WMO) ; Kepert Jeffrey David; Ginger J.D. - WMO, 2010 (WMO/TD-No. 1555)PermalinkWorld Meteorological Organization (WMO) ; Economic and Social Commission for Asia and the Pacific (ESCAP) - WMO, 2009 (WMO/TD-No. 1476)PermalinkPermalinkPermalinkThis expert meeting was organized in response to the recommendations of the Sixth International Workshop on Tropical Cyclones to develop a common set of metrics to evaluate the skill of seasonal tropical cyclone forecasts and report on a central website hosted by WMO. Camargo et al. summarized in the October 2007 issue of the WMO Bulletin a number of statistical and dynamical seasonal forecasts. Representatives of each type of forecast were part of the expert team. Issues confronted when attempting to conduct an evaluation of forecasts produced by different groupsPermalinkPermalinkWorld Meteorological Organization (WMO) ; Economic and Social Commission for Asia and the Pacific (ESCAP) - WMO, 2008 (WMO/TD-No. 1448)PermalinkPermalinkThis module is intended for experienced forecasters moving from a land-based area to a coastal or Great Lakes region where both over-land and over-water forecast areas exist. This module highlights the differences between marine boundary layer and terrestrial boundary layer winds. The experienced forecaster is relatively familiar with the boundary layer over land and the associated implications for the wind field. Using this as a base, the module compares this known quantity with the lesser-known processes that occur in the marine boundary layer. Three major topics that influence marine bounda ...PermalinkPermalinkis an issue of MétéoMonde. OMM, 2004Contient:

Microwave data from polar-orbiting satellites is crucial to today’s operational forecasters, and particularly for those with maritime forecasting responsibilities where in situ observations are sparse. This module includes information on storm structure and techniques for improved storm positioning using the 37 and 85-91 GHz channels from several satellite sensors. Information on current sensors and on the product availability in the NPOESS era is also presented.PermalinkPermalinkPermalinkA scientific introduction to the El Niño/Southern Oscillation (ENSO) phenomenon, with special focus on implications for climate prediction and disaster preparedness. This 8-page brochure traces El Niño from its first observation and presents a detailed account of the noteworthy 1997-98 event. Issued in connection with World Water Day 2004.PermalinkWorld Meteorological Organization (WMO) ; United Nations International Strategy for Disaster Reduction (UN/ISDR) - WMO, 2004 (WMO-No. 971)To reduce the risk due to water-related disasters, the watchword is to “be informed and be prepared”. Information must flow between global and local, between traditional and modern,
between the village and the boardroom, between scientists and decision makers. This booklet is an attempt in that direction, and it is hoped that national governments and all those concerned by the issue will find it useful and informative.Permalink
