What local conditions produce variation in the Mediterranean Type of climate?

As the Mediterranean region lies between the Tropical Deserts on the equatorward side and Cool Temperate West Margin region on the poleward side, it shares the summer drought conditions of the deserts at lower latitudes and rain in winter.

Many local variations are produced in the Mediterranean region-

1. In the Mediterranean region, considerable East-West extent of the sea allows the westerly influence of winds to penetrate deep into the Afro-Asian landmass.
2. On account of the local conditions and indented coastline, many local variations of the winds are produced.
3. The Westerlies and the temperate cyclones travel from west to east and bring rainfall in decreasing order.
4. In addition, cold Polar winds in winter are also sometimes drawn into the circulation of depressions like Mistral in the Rhone valley and Bora in the northern Adriatic Sea region. They cause great devastation.
5. Southern winds like Sirocco in North Africa are hot and dry. They cause considerable damage to crops.
6. Such weather patterns also occur in Oregon in USA, California, Cape Town in South Africa and central Chile.
