Trade winds are most regular of all the planetary winds and in general they blow with great force and in constant direction.
Since trade winds blow from the subtropical latitudes to the warmer equatorial latitudes, they have great capacity of holding moisture.
In their passage across oceans, they gather more moisture and bring heavy rainfall to the east coast of continents.
As their offshore on the west coast, these regions suffer from great aridity and form hot deserts of the world.
E.g. Sahara, Kalahari, Atacama, Great Australian deserts.
