Damage from Hurricane Andrew. High winds are known to cause damage, depending upon the magnitude of their velocity and pressure differential. Wind pressures are positive on the windward side of a structure and negative on the leeward side. Infrequent wind gusts can cause poorly designed suspension bridges to sway.
Very high winds can be caused by mature tropical cyclones (called hurricanes in the United States and Canada and typhoons in eastern Asia). A tropical cyclone's heavy surf created by such winds may cause harm to marine life either close to or upon the surface of the water, such as coral reefs. [42]
Wind storm – A storm marked by high wind with little or no precipitation. [8] Windstorm damage often opens the door for massive amounts of water and debris to cause further damage to a structure. [9] European windstorms and derechos are two type of windstorms. [10] High wind is also the cause of sandstorms in dry climates.
To form the Santa Ana winds, the typical first ingredient is a chilled autumn day in the high desert of southern Nevada. The chill creates cold, dense air, which is squeezed from aloft by a high ...
A downburst is created by a column of sinking air that, after hitting ground level, spreads out in all directions and is capable of producing damaging straight-line winds of over 240 kilometres per hour (150 mph), often producing damage similar to, but distinguishable from, that caused by tornadoes. This is because the physical properties of a ...
At the 60th parallel, the air rises to the tropopause (about 8 km at this latitude) and moves poleward. As it does so, the upper-level air mass deviates toward the east. When the air reaches the polar areas, it has cooled by radiation to space and is considerably denser than the underlying air. It descends, creating a cold, dry high-pressure area.
Tate said the predicted wind drop will at least be “enough that firefighting aircraft can get airborne again and try and attack the fires from the air.” With Post wires Show comments
It could also be created in other phenomenon, such as a cold front. Even if the air is cooler on the surface, there is still warmer air in the mid-levels, that can rise into the upper-levels. However, if there is not enough water vapor present, there is no ability for condensation, thus storms, clouds, and rain will not form.
