So his first paragraph of the book is like, oh, we didn't know that this was serious.

And then we realized that it was serious in World War II.

It's super different.

So the first thing that's like there are some really guiding principles for the mid-latitude dynamics that we teach in the classroom.

For example, we have this thing called.

this very important balance that's called geostrophic balance.

So if you look at the major weather patterns, you have the jet stream, right?

Yeah, yeah.

So commercial aircraft take advantage of the jet stream, and then they fly along the jet stream to make the flight faster, but then they have to fly against it on the way back, so it is actually slower.

Right.

So we know that these currents exist, and they're actually in a very, very elegant balance.

The winds want to accelerate to the poles, but then the Coriolis force, which is the bending effect that you get from the planet being in rotation, it bends it the other way.

So it causes all the combination of these forces creates the jet stream.

And the jet stream goes from west to east.

And in this jet, you get these waves.

So you get these undulations.

And these undulations are the troughs and ridges that create our day-to-day patterns.

So that's why temperature fluctuates a lot.

The colder side of the jet is really cold.

The equator one is warm.
