LA basin wind patterns

[Richard]

The following airports are shown from east to west in the eastern portion of the Los Angeles basin. KFUL is to the south and is included as kind of a 'control' and indicator of what the winds are away from the mountains at the north perimeter of the basin.

What the heck is going on with the winds? I think I'll never figure out the winds here. I think perhaps there is a convergence zone caused by mtn terrain near KPOC but that's just a WAG.

Looks like a pretty typical "Santa Ana" wind pattern as the high pressure center migrates toward the east. I learned to fly at Fullerton in the '60s, and if runway 6 was in use I knew it would be an interesting lesson that day.

Negative on the Santa Ana winds. The lifted index is marginal, there is a 1011 Mb Low offshore of Ensenada with a upper lvl trof extending just off shore of SoCal, making landfall at Pt Conception and going up inland of the coast all the way into OR.

EDIT: The trof basically parallels the jet stream.
