Meteorologist Donald M. Gales’ diagrams of temperature inversion levels over Palos Verdes Peninsula may help some understand why winds reverse at different elevations over Los Angeles. During sunny High pressure, our West ground winds are opposite of the East-to-West cirrus disappearance in the satellites, caused by sublimation/evaporation from dry, sinking air aloft and adiabatic heating.

Planes avoid these levels because they’re gusty if desert and ocean air are meeting each other, and turbulent if temperatures reverse. (Also, they avoid skyscrapers.)
As in this picture, at the ground level in L.A.’s coastal plain on High pressure days, it is still, calm, not windy when we wake up, or very, very light winds, variable in direction, wispy.
We have received a record number of cards and condolences, and hosted a memorial gathering at my dad’s home rather than the church. People kept pouring in, and everyone said similar things about my mom, that she always, always made them feel good, and was so sweet to everyone.

10/20/14 Hi, the post, “Weather Diagrams for Beginners,” has several topics that will be on Test 2: these should already be in your class notes and handouts, but I recommend looking through them and making sure you know it: http://drmrenfrew.wordpress.com/2014/10/17/weather-diagrams-for-beginners/
Note: I did not find out about my mom passing till late Sunday night, but I’m sure she is happy I was having fun and want to share the photos.
It was free/included as part of our church retreat at Forest Home in Forest Falls.
It was really fun, 2 runs.
The only scary part was a fraction of a second before you arrive at the platform: there are ‘brakes,’ but it is very fast and you are not in control.
