The Centre is really is an area dominated by land arid and semi-arid, with important places of extreme aridity. In the northern part of the region, a steppe climate dominates, with cold winters and warm summers. A thin contiguous zone to the Mediterranean Sea is classified as a Mediterranean area, with moderately comfortable, wet winters and dry summers, while the central component and the South with the base of the Arabian peninsula is very dry out with very hot summers and moderate temperatures in winter.
Water is a very limited resource. Droughts, desertification and water shortages are permanent elements of life in most countries of the zone. The native plants and animals is adapted to cope with severe climate problems sequences. Through Middle East, summer temperatures are generally around 30? C, but often gliding over 40? c.
However, in the desert of Saudi Arabia, temperatures above 45? (c) are typical. In the summer, winds blow tirelessly towards the warm interior of the Arabian Peninsula, while in winter, the South winds of the Earth. In the northern regions, continental winds out some rain to coastal and mountain ridges behind.Precipitation is low in the section most of the region, but it is highly variable depending on the seasons and inter-annually.
The exception of the southern part of the Arabian Peninsula with the rain in summer time, rainfall occurs in the Middle East during the winter. Summer desiccated hard period of 6-10 months (UNEP, 1997). On average each year varies from precipitation 0 mm to 200 mm, only in the components of the Northwest along the Mediterranean Sea, to the bottom of the Turkey to the Lebanon and also the northern part of Palestine and the Jordan values exceed 500 mm and more.
No there was no discernible trend in annual precipitation in the last century (1901-99) for the region as a whole, nor in most of the region except in the southwestern part of the Arabian Peninsula, exactly here where there was a significant improvementHowever, from a very low base rain.
In typical with other countries in this drinking water scarce region in the aridic in the North, East of Centre belt has chronic difficulties of drinking water resources. The region is facing an enormous imbalance between demand and available water, exactly where water shortage is becoming permanent in nature. Due to its scarcity of drinking water is really a valuable resource that is essential to the socio-economic improvement of the Middle East.
