I wonder why the tropics are hot.
They get the sun quite a lot
But 12 hours of night should put heat to flight
I wonder what else they have got. …
So what makes equatorial regions hot?
There is not that much land there. Heated water washes away quickly and anyway runs deep. A layer of water absorbs light (heat) to a depth of hundreds of feet if it is clear. And tropical seas are usually fairly clear.
Most light is reflected off the surface at early morning and late evening angles and any hitting land has a similar but lesser problem. plus it leaves at night.
Desert areas such as the semitropical Sahara can leave you dead from exposure if you go clad only for daytime temperatures. Even with such albedo problems deserts in places like Lybia can be deadly hot. And it tends to lose that heat slowly, I admit.
But there are thousands of miles of such desert.
How do the tropics heat up? They are known to have high humidity. But doesn't that mean an high albedo too?
