what are the santa ana winds?
528928
Santa Ana winds are strong, dry downslope winds in Southern California and northern Baja California. They're caused by clockwise circulation around areas of surface high pressure east of the Sierra Nevada in the Great Basin region.

What are the trade winds? The trade winds are just air movements toward the equator. They are warm, steady breezes that blow almost continuously. The Coriolis Effect makes the trade winds appear to be curving to the west, whether they are traveling to the equator from the south or north.

Foehn winds can arise as a result of humid airflow over a mountain range. The air is drawn up on the windward side of the mountains and rises wet adiabatically (reduction in temperature around 0.6°C/100m).

Contrast surface winds and upper-air winds in terms of speed and direction. A. Upper air winds generally parallel the isobars, the result of the pressure gradient force and the Coriolis effect balancing one another. However, near Earth's surface, friction slows the winds.

The National Weather Service defines “breezy” and “windy” differently, winds 15 to 25 mph are considered “breezy” and above 25 mph are considered “windy.” The other challenge we run into with wind forecasts are the micro-climates we have across southern Idaho.

Santa Anas are dry, warm and gusty northeast winds that blow from the interior of Southern California toward the coast and offshore, moving in the opposite direction of the normal onshore flow that carries moist air from the Pacific into the region.

Upper-air winds are faster than surface winds because friction is greatly reduced aloft. Friction slows surface winds, which in turn reduces the Coriolis effect. The result is air movement at an angle across the isobars toward the area of lower pressure.

The prevailing winds are the bases of the Hadley, Ferrell, and polar cells. These winds greatly influence the climate of a region because they bring the weather from the locations they come from. Local winds also influence local climate. For example, land breezes and sea breezes moderate coastal temperatures.

Wind is air pressure converted into movement of air. When air slows down, its pressure increases. The kinetic energy or momentum of a moving air mass is converted in static atmospheric pressure as the air mass slows down. This means that higher wind speeds will show lower air pressure readings.

An N2 classification means the house has to stand up in winds of 26m/sec (93.6 kmh) and gusts of 40m/sec (144 kmh).

All wind is caused by the uneven heating of Earth's surface, which sets convection currents in motion. Convection currents on a large scale cause global winds; convection currents on a small scale cause local winds.

Damaging winds are classified as those exceeding 50-60 mph. ... Wind speeds can reach up to 100 mph and can produce a damage path extending for hundreds of miles.

The global wind system is created by air blowing from areas of high pressure to areas of low pressure. Winds are affected by the Coriolis effect. In the Northern Hemisphere the Coriolis effect deflects movement to the right and in the Southern Hemisphere it deflects movement to the left.

A gale is a strong wind, typically used as a descriptor in nautical contexts. The U.S. National Weather Service defines a gale as 34–47 knots (63–87 km/h, 17.5–24.2 m/s or 39–54 miles/hour) of sustained surface winds. Forecasters typically issue gale warnings when winds of this strength are expected.

No. In space there is no air, so no wind as per the common definition. However, there is something called solar wind. Solar winds are streams of particles emitted from stars, including our sun.

There are three types of wind that are associated with wildland fire: general winds resulting from atmospheric activity, local winds resulting from unequal heating of land and sea surfaces, and winds resulting from a fire's buoyancy (also called entrainment).
