Question Why wind in Apple Valley?

Does anyone know the scientific explanation for the daily winds in Apple Valley? Quiet in the morning, but blowing by noon. Why?

Cajon Pass has a lot to do with it. Pressure differentials between the two distinct geographical areas on either side of it.

Okay, I gotta ask ......

The wind blows free. How much do you charge?

Well, thank you, Fontucky. I kept thinking, it's the difference in pressure, but wasn't thinking BIG and WIDE enough. Think I'll go study my relief map.

That Cajon Pass connection works both ways. It provides us on this side with nasty and destructive Santa Ana Winds when the Great Basin has a big fat high pressure system stalled over it. The evil part of the Santa Anas are born in the passes and canyons, and when they exit the mouth of Cajon Canyon, one of the first places they see is Fontana and my roof, which just happens to be oriented North and South so the shingles can get the full effect of the huge gusts.

I lived in Spring Valley Lake for 10 years growing up. The explanation of this that I was given was that the hot air rises up and mixes with the colder air up high and is forced back down by the mountains. That explains why it's so windy in the summer at not so windy other times of year, I guess.

Fascinating information. We moved recently to Spring Valley Equestrian estates and I heard that when these fierce summer winds turn cold in the winter, it's vicious. I'm somewhat relieved to hear that winter winds are less, and with the Santa Ana's involved, it makes sense that summer is the windiest. Good. So I don't need to buy a subzero coat when Burlington Coat Factory finally opens?
