[5] Due to the effects of climate change , the frequency and intensity of some of the extreme weather events are increasing, for example, heatwaves and droughts .
Based on satellite imagery, the Dvorak technique is the primary technique used to estimate globally the tropical cyclone intensity. [19]The Potential Intensity (PI) of tropical cyclones can be computed from observed data, primarily derived from vertical profiles of temperature, humidity and sea surface temperatures (SSTs).
A weather cancellation or delay is closure, cancellation, or delay of an institution, operation, or event as a result of inclement weather. Certain institutions, such as schools, are likely to close when bad weather, such as snow, flooding, air pollution , tropical cyclones , or extreme heat , causes power outages , or otherwise impedes public ...

Although the snow accumulation is not significant because they are so brief -- typically 1 to 2 inches may fall -- snow squalls can create hazardous driving conditions due to the sharply reduced ...
Severe weather can occur under a variety of situations, but three characteristics are generally needed: a temperature or moisture boundary, moisture, and (in the event of severe, precipitation-based events) instability in the atmosphere.
WAS*IS was formed to build an interdisciplinary community of practitioners, researchers and decision makers collaborating to effectively understand how to improve weather warnings, incorporate societal impacts into weather forecasts, and use social science tools and methods. WAS*IS is changing the culture from what WAS to what IS the future of ...
