Clouds which form above regions within trade wind regimes are typically composed of cumulus which extend no more than in height, and are capped from being taller by the trade wind inversion.
2.
Shallow cumulus clouds are seen within trade wind regimes, and are capped from becoming taller by a trade wind inversion, which is caused by descending air aloft from within the subtropical ridge.

They normally reside over maritime tropical air masses, forming a warmer and drier layer over the more moderate moist air mass below, forming what is known as a trade wind inversion over the maritime tropical air mass.
