The damage caused by Hurricane Andrew is a good example of the damage caused by a category 5 Tropical cyclone. A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain or squalls.
Precipitation is measured using a rain gauge, and more recently remote sensing techniques such as a weather radar. When classified according to the rate of precipitation, rain can be divided into categories. Light rain describes rainfall which falls at a rate of between a trace and 2.5 millimetres (0.098 in) per hour. Moderate rain describes ...
The annual question reaches peak curiosity this week, but as the planet warms due to human-caused climate change, the probability of seeing snow at Christmas is becoming increasingly unlikely ...
There are several types of urban flooding, each with a different cause. City planners distinguish pluvial flooding (flooding caused by heavy rain), fluvial flooding (caused by a nearby river overflowing its banks), or coastal flooding (often caused by storm surges). Urban flooding is a hazard to both the population and infrastructure.
The recent heat and lack of rainfall has caused virtually all of North Carolina to either enter drought conditions or be classified as abnormally dry, according to the N.C. Drought Management ...
In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation. On the leeward side of mountains, desert climates can exist due to the dry air caused by compressional heating. Most precipitation occurs within the tropics [3] and is caused by convection.
Fronts are the principal cause of significant weather. Convective precipitation (showers, thundershowers, heavy rain and related unstable weather) is caused by air being lifted and condensing into clouds by the movement of the cold front or cold occlusion under a mass of warmer, moist air.
(The Heavy Rainfall Warning product issued by the Meteorological Service of Canada has a similar meaning as an NWS Flash Flood Watch.) [13] Particularly dangerous situation flash flood watch FFA – Conditions are favorable for an extremely elevated level of severe and life-threatening flash flooding beyond the level of a normal flash flood ...
