2.12 The seasons in the tropics

 

Frank L. Preuss

 

The following table shows, coming from the north, the Tropic of Cancer, that the high point of the summer turns into two high points, and how at the same time then also two winter high points exist.

Then there are in the tropics 8 instead of 4 seasons, when one can call something like this seasons.

The distance between summer and winter is not like in the temperate parallels everywhere 6 months, but varies from 6 to zero. But all lengths of the seasons added together also result in one year.

Then, at the transition from the tropics to the subtropical area at the Tropic of Capricorn, the 8 season come again together, and there are again just only 4 seasons.

At the tropics the two summer high points therefore come so close together in the tropics, that they then, in the subtropical areas, become one summer. And with it also the winter in between drops out.

And the table also shows that the two high points of the two summers are time wise different on different parallels, but not those of the two winters, they always agree with the two solstices.

Then one can also see that at the equator, therefore in Quito, the two summer high points fall on the two equinoxes. That is therefore the exact opposite of the situation outside of the tropics, where the summer high point is furthest away from the equinoxes.

The speed with which the sun moves from one tropic to the other, is greatest at the equator, and becomes zero towards the tropics.

The table also shows how winter changes over from the northern hemisphere in December, to the southern hemisphere in June. And how the summer changes over from the northern hemisphere in June to the southern hemisphere in December.

Outside of the tropics summer and winter are opposites, within the tropics winter is a constant and summer a variable. The two summers move between the two winters; the two winters remain at the same place time wise.
