Kenneth, you really are pathetic. The winds heat up because of the mountains. The wind then dries the brush...

Mountains help create hot, dry Santa Ana winds

Several meteorological factors come together to create the hot, dry Santa Ana winds that often whip up roaring fires in Southern California.

The factors needed to stir up Santa Ana winds usually begin with a high-pressure area to the northeast of Southern California.

Winds blow clockwise around high pressure in the Northern Hemisphere, which means that winds on the southern side of the high blow from the east toward the Pacific Ocean, toward lower offshore air pressure.

The easterly winds push dry air from over the inland deserts of California and the Southwest.

The winds blow over the mountains between coastal California and the deserts. As the wind comes down the mountains, it's compressed and warms up.

As the air warms, its relative humidity drops, sometimes to less than 20% or even less than 10%. The extremely low humidity helps dry out vegetation, making it a better fuel for fires.


As the winds squeeze through canyons and valleys they speed up, fanning flames. In addition, as the winds whip over mountains and squeeze through canyons, friction helps create eddies, or swirling winds. As these come and go, the air can become almost still and then quickly speed up in gusts.

The winds are like water rushing down a very rough whitewater stream, creating eddies that come and go. These gusty winds can change direction quickly, sending flames racing into new areas.

Fires also affect the winds. Fire warms the air, causing it to rise. As this happens, more air rushes into to replace the rising air, helping create more gusts from various directions.

If the brush wasn't so dry, it wouldn't burn so hot. The brush was so dry because of the global warming drought.
