**Separation of Influences** Cause and effect can be reversed in our influencer land. In physics land, the stratosphere is influenced by surface temperatures through massive clear-air convection cells, which haven't been measured since the 70's.
I'm not doing 'physics and weather' hashtags any more. I have no effect.
However, the Jet Stream is totally an effect of warm and cold air masses colliding. That's where the energy comes from. However, influencers will state that the JS can influence surface weather, effectively moving air masses, when, in fact, it is being moved by the air masses. The physics for this is only available in physics-land and wiki-thing.
I only object to this thinking because Old Occam says the tail cannot wag the dog. But in our modern world, the tails are all over the place, because that is interesting. Physics is not.... And the weather guys have to make things interesting, or they are off the air.
ps. I've never realized that when you eliminate physics, then 'cause and effect' are fluid concepts. In my alternate dimension of physics, entropy dictates that energy must flow from cause to effect, and that 'cause' is much higher energy. But in debate, nobody calculates energy.
And now I'm thinking of sailing on the lake in the summer. The wind is horrible because of the surrounding highlands, so I'm always looking for tiny ripple patterns. They indicate a huge convection vortex is about to hit me, and I prepare. Without measuring the huge energy of the vortex, I could think the ripples are going to hit me, or that the ripples bring the wind.
