pogoda: Severe weather

Evidence: 100 • authority: 72

Severe weather is any dangerous meteorological phenomenon with the potential to cause damage, serious social disruption, or loss of life. These vary depending on the latitude, altitude, topography, and atmospheric conditions. High winds, hail, excessive precipitation, and wildfires are forms and effects, as are thunderstorms, downbursts, tornadoes, waterspouts, tropical cyclones, and extratropical cyclones. Regional and seasonal phenomena include blizzards, snowstorms, ice storms, and duststorms. Severe weather is one type of extreme weather, which includes unexpected, unusual, severe, or unseasonal weather and is by definition rare for that location or time of the year. Due to the effects…

Extreme weather includes unexpected, unusual, severe, or unseasonal weather; weather at the extremes of the historical distribution—the range that has been seen in the past. Extreme events are based on a location's recorded weather history. The main types of extreme weather include heat waves, cold waves, droughts, and heavy precipitation or storm events, such as tropical cyclones. Extreme weather can have various effects, from natural hazards such as floods and landslides to social costs on human health and the economy. Severe weather is a particular type of extreme weather which poses risks to life and property. Weather patterns in a given region vary with time, and so extreme weather can…

FAIR WEATHER FRIENDS AND WEATHER AUTHORITIES: LOCAL BROADCAST METEOROLOGISTS IN SEVERE WEATHER EVENTS. As a currently-peripatetic academic, I often live and travel in areas that are meteorologically interesting. Between growing up somewhere that can give residents all four seasons in a single day (not to mention metres of snow at a time)[1] and then living in a series of deserts, tropical savannahs, highlands and seasides, listening to or watching local weather forecasts has long been an integral part of my daily life.

Heat and Severe Weather. A hotter climate means there will be more heat waves and heat-related illnesses, such as heat exhaustion and heat stroke, the leading causes of weather-related death in the US. Without mitigation, annual world-wide heat-related deaths may exceed 225,000 by 2050. Heat will spawn more extreme weather events such as severe thunderstorms, and tornadoes. Although the number of hurricanes may not increase, the moisture-laden air and warmer oceans will make those that do form more intense and deadly.

7. Severe and unusual weather events. Convective clouds may range from relatively innocuous showers to major supercell systems accompanied by dramatic conditions. ‘Severe and unusual weather events’ explains how convective cells generate in cumulonimbus clouds and how thunderstorms and associated lightning develop. Convective clouds may cluster together resulting in vigorous circulation and heavy precipitation. Even more active and dramatic systems are supercells that create tornadoes. These arise when a deep pool of unstable air is accompanied by a strong increase in wind speed with height, together with directional wind shear. Tropical cyclones are closed, non-frontal, low-pressure system…

An Entropy Generation Rate Model for Tropospheric Behavior That Includes Cloud Evolution.. A postulate that relates global warming to higher entropy generation rate demand in the tropospheric is offered and tested. This article introduces a low-complexity model to calculate the entropy generation rate required in the troposphere. The entropy generation rate per unit volume is noted to be proportional to the square of the Earth's average surface temperature for a given positive rate of surface warming. The main postulate is that the troposphere responds with mechanisms to provide for the entropy generation rate that involves specific cloud morphologies and wind behavior. A diffuse-interface…
