Winds in the Marine Boundary Layer: A Forecaster's Guide
This 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 ...
Mesoscale Banded Precipitation
Precipitation frequently falls and accumulates in discrete bands with accumulations that vary markedly over short distances. This module examines several mechanisms that result in mesoscale banded precipitation, focusing primarily on processes at work in midlatitude cyclones. The module starts with a review of the Norwegian and conveyor belt cyclone models. Then several banding processes are examined in detail, including deformation/frontogenesis, the Trowal (Trough of Warm Air Aloft), frontal merger, CSI/slantwise convection, and melting/evaporation-induced circulations. The module concludes ...

Polar Satellite Products for the Operational Forecaster: Microwave Analysis of Tropical Cyclones
This module introduces forecasters to the use of microwave image products for observing and analyzing tropical cyclones. 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.
El Niño at a glance
A 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.
Water and disasters: be informed and be prepared
World 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.
L'eau et les catastrophes : être informé et préparé
Organisation météorologique mondiale (OMM); Stratégie Internationale pour la Prévention des Catastrophes (SIPC) - OMM, 2004 (OMM-No. 971)Pour réduire le risque de catastrophes liées à l’eau, il faut avant tout être informé et préparé. L’information doit se transmettre du niveau mondial au niveau local, de la sphère traditionnelle au monde moderne, du village à la salle du conseil d’administration, des scientifiques aux décideurs. La présente brochure a été conçue dans cette optique, et nous espérons que les gouvernements et tous ceux qui s’intéressent à ces questions la trouveront utile et instructive.
