I’ve never understood the mechanics of rain. I get that when the barometer reading is beneath a certain point that the rain will fall. What I don’t get is how, with the pressure of the clouds over the land, atmospheric pressure falls. And why it rises when the sky above is clear.
Today, a hard wind blows off the mountain. I think this means that there is a low pressure system in the valley below me. The pines bend over and their needle clumps look like the fluff on poodles. The street is clean from the rain and the wind. If there is trash, it is caught in the cul de sac, out of my view.
