What kind of winds does California have?
Santa Ana Winds occur when air from a region of high pressure over the dry, desert region of the southwestern U.S. flows westward towards low pressure located off the California coast. This creates dry winds that flow east to west through the mountain passages in Southern California.

Why are California winds so strong?
The Diablo wind is created by the combination of strong inland high pressure at the surface, strongly sinking air aloft, and lower pressure off the California coast. While hydraulic jumps can occur with Santa Ana winds, the same thermodynamic structure that occurs with them typically favors “gap” flow more frequently.
What are prevailing winds and how do they work?
Prevailing winds are winds that blow consistently in a given direction over a particular region on Earth. Due to factors such as uneven heating from the Sun and the Earth’s rotation, these winds vary at different latitudes on Earth.
What are examples of prevailing winds?
Polar easterlies are dry, cold prevailing winds that blow from the east. They emanate from the polar highs, areas of high pressure around the North and South Poles. Polar easterlies flow to low-pressure areas in sub-polar regions. Westerlies are prevailing winds that blow from the west at midlatitudes.
Are prevailing winds warm?
The unequal heating of the earth’s surface drives the prevailing winds. Warm air rises in the tropics and is replaced by air flowing in from higher latitudes. High above the earth the air flows away from the ITCZ, cools and sinks at about 30 ° latitude. …
