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.
Panorama of a strong shelf cloud, which can precede the onset of high winds. High winds are known to cause damage, depending upon their strength. Wind speeds as low as 23 knots (43 km/h) may lead to power outages when tree branches fall and disrupt power lines. [15] Some species of trees are more vulnerable to winds.
Heavy, wet snow poses unique challenges and threats in a winter storm: it can cause heart attacks in people shoveling snow, lead to power outages and roof damage, and cause hazardous conditions on ...
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.
Eastern Maine had the highest number of wind damage reports, The storm's pressure dipped the required 0.71 of an inch of mercury (24 millibars) in less than 24 hours between Wednesday and Thursday ...
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 ...
Straight-line winds (also known as plough winds, thundergusts, and hurricanes of the prairie) are very strong winds that can produce damage, demonstrating a lack of the rotational damage pattern associated with tornadoes. [10] Straight-line winds are common with the gust front of a thunderstorm or originate with a downburst from a thunderstorm ...
