Weather and Emergency ManagementKent M. McGregorAssociate ProfessorDepartment of Geography University of North Texas Denton, TX 76203 - 5279 e-mail: m chapter - weather and emergency mgmtmcgregor@unt.eduABSTRACTThe science of meteorology is deeply intertwined with the process of emergency management. Weather phenomena are the cause of many disaster events such as tornadoes and hurricanes and a factor in many others. Weather can also affect the way assistance is provided during or af chapter - weather and emergency mgmtter an emergency. Since time to prepare is vital, much of meteorology is concerned with forecasting and issuing. This paper addresses the role of metechapter - weather and emergency mgmt

Weather causes many disasters that require an emergency response. Indeed meteorological chapter - weather and emergency mgmt processes determine the extent of the destruction to life and property.Meteorologists both forecast the impending event and survey the scene afterwarchapter - weather and emergency mgmt

McGregorAssociate ProfessorDepartment of Geography University of North Texas Denton, TX 76203 - 5279 e-mail: m chapter - weather and emergency mgmtcal processes. This includes the duration of the event, the duration of the consequences, and the scale of the impact. These are important considerations in determining the type of emergency response and the allocation of resources. The second section covers the process of developing a weather forec chapter - weather and emergency mgmtast and disseminating the result.

The fourth section is the majority of the paper and reviews the major types of weather events that might require an emergency response. These are tornadoes, hurricanes, floods, droughts, heat waves, wild fires, and blizzards. It includes a discussion of the basic atmospheric p chapter - weather and emergency mgmtrocesses causing each event with selected examples. The examples come from both the U.S. and countries around the world. The international perspectivechapter - weather and emergency mgmt

These include continual development of models and supporting observation networks. Extreme weather events are increasing viewed in the larger context of global atmospheric and oceanicforces. The best known of t chapter - weather and emergency mgmthese is global warming. However, many regional climate cycles 01 oscillations have a pronounced affect on weather and extreme weather events. The F.lchapter - weather and emergency mgmt

Table 1 summarizes many of these weather related hazards. Of the twenty (20) items in this list, twelve (1 chapter - weather and emergency mgmt2) are caused directly by atmospheric forces, and weather is a factor in the remaining eight (8).Table 1.
