Iran's climate

Climate in Iran sharply continental, very hot both dry in the summer and cold, with loss of a small amount of snow in the winter. The fertile earths concentrated in basic in the North-West and the West, including Lurestan, Kurdistan and Azerbaijan, receiving plentiful and rather constant rain deposits and despite noted seasonal differences of temperatures, give the big harvesting owing to what the farming here prospers.

     Climatic contrasts in Iran are that, that one tourists can be engaged in winter kinds of sports in mountains while others can bathe at several o'clock driving from large cities.

     Contrast in climatic conditions between various regions has generated landscape greatness of a landscape. The extensive southern territory of the country is stretched from Khuzestan along a narrow strip of plains and the hills adjoining Persian gulf, and also in mountains Mokran in Baluchistan. Here exhausting heat with rare and poor rains is observed. The plain of Khuzestan has the processed earths with a fertile soil which is cultivated during a time interval when river water becomes accessible for irrigation by means of numerous channels which last from the rivers which are flowing down from Zagrossk Mountains to the north.

     Within all 2500 the most effective method in struggle with on plateau of Iran severe climatic conditions building of ganats (underground water channels) was dominating. The method which was used up to now, has found the application in other countries of Middle East, the countries of Africa and even in Spain. The total length of Iranian ganats makes about 40 000 km. Iran also is the country of the most ancient in the world of dams, the majority from which is in an excellent condition.

     Despite of everything, the climate of Iran favorably differs in comparison with other countries of Middle East. More than one third of all earth of Iran receives annually 250 mm of rain deposits on the average while strong winter deposits in mountains which surround the central plateau, provide stocks of water for irrigation of spring crops. Firdausi, the well-known Iranian epic poet, has described southern coast of Caspian sea as a valley where the spring reigns all year.
