Location of Hot
Deserts.
The largest arid and semi-arid deserts occur
between latitudes 15° and 30° North and South of
the equator.
Most of these deserts are located on the western
sides of the continental masses on which they lie.
They occur within the Trade wind belt where the
winds are off-shore.
Off-shore winds are those winds that blow from the
shore towards the ocean.
These winds (Trade winds) tend to be dry after
loosing their moisture as they journey across the
eastern side of contents.
Although west coasts have on-shore winds (winds
from the ocean towards the land) blowing towards
them, they rarely bring rain.
This is because the onshore winds meet with cold
currents that blow parallel to coast lines (e.g. the
Cold Benguela current in the case of the Kalahari
and the Cold Angola current in the case of the
Namib desert) this causes the moisture w...
