Since semiarid climates are found surrounding arid climates, its no surprise they are dry areas. An area is considered semiarid if it averages between 10-20 inches of rain annually (yearly). Some years these places may get 20-40 inches of rain, but sometimes 5-10--this is why they are semi-arid and dangerous for human settlement.
The equatorial, hot, wet climate is found between 5° and 10° north and south of the equator. Its greatest extent is found in the lowlands of the amazon, the congo, malaysia and the east indies.

Rock particles that wash down from mountain sides collect in adjacent basins, in some places burying the bedrock under thousands of feet of rock debris.
A semi-arid climate, semi-desert climate, or steppe climate is the climate of a region that receives precipitation below potential evapotranspiration, but not as low as a desert climate.
