Geography: why is desert uncommon along the equator?

Self-tutoring about geography: the tutor inquires why deserts exist mainly outside the tropics.

The sun is most intense at the equator, so air rises most dramatically from the Earth’s surface along the equator. Rising air causes low pressure, which facilitates evaporation. Therefore, along the equator is typically wet.

There are exceptions, however – for instance, the desert in Somalia.
