My daughter says that she learned in science class that hurricanes in the north hemisphere turn counter clockwise and clockwise in the south hemisphere

That depends on whether you're watching them from the ground or from space.

It is not just hurricanes that do that. Low-pressure systems are the same. High-pressure systems go in the opposite way to low-pressure systems in the same hemisphere.

Weather systems are viewed from above. If they are viewed from the ground then they are viewed horizontally.

With the wind on your back the low is on your left.

And the same thing that makes them spin the way they do also makes them take the courses they take on a map. Do an image search for hurricane & typhoon paths/tracks and you'll see that they repeatedly form in the same regions and follow the same curved paths, veering to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

What the northern right curves and southern left curves have in common is that they both veer away from the equator. The net result of the forces that are pushing & pulling on them is like a push/pull away from the equator.

I would use that fact in an analogy to explain to people how financial life in the economy works, but I don't think enough people would get it because not enough people know about hurricane/typhoon paths. The idea is that there's a financial "equator" that people are always getting pushed away from. If you're below it, you keep encountering feedback loops that push you lower, and if you're above it, you keep encountering feedback loops that push you higher. As a result, it's so difficult to cross in either direction that most people don't know it's there because (unlike me) they've spent their whole lives on the same side of it. So the analogy with tropical storms and the equator would be a nifty succinct way to tell people that the financial equator exists too... except that an analogy between X and Y to explain Y as being similar to X in some way only works if the audience is already familiar with X.

Cool thanks! In the 80’s I saw someone get raises and promotions because he had a cool car and rich family so I can sort of see how that works

Learned this yesterday from the National Audubon Society: Eastern skunk cabbage is thermogenic.
