2 Principal Component Analysis (PCA) Precipitation The climate of the basin is classified as Mediterranean. It is characterized by wet cool winter and long hot dry summer. The principal meteorological factors which produce precipitation are cyclonic disturbances forming over the Mediterranean sea, or Atlantic ocean. In summer the subtropical region of the Azores anticyclone, establishes itself over the coastal area of the Mediterranean, thereby preventing the penetration of the cyclones from the sea into the Eastern Mediterranean region. In spring a low pressure area is formed resulting in the movement of the Khamasin wind system into Syria and adjacent areas. Precipitation varies over the Barada river basin from about 000 mm. in the Zebdani highlands to about 00 mm in the eastern lowlands. It occur mainly from October to May. The period from December to February accounts for 5 to 65% of the annual precipitation. virtually no rain falls from June to September. The total amount of precipitation on the basin is 67 mm or 566 MCM (Million Cubic Meters). some 8 mm or 0 MCM on the average, fall on the Damascus plain (Selkhoprom export, 87). ٣ Principal Component Analysis (PCA) Precipitation data between 6 76,For 8 Stations sn Year month 6,5,5,6,,6 6, , 7,8,5, 6, 7 6 5, 5, 8,6 85,6, 07,5 6 76,7 67,,5,6 08,5 6, 77, ,7,,5 8,, 7, 6 6,5, 0, 0,5, 5,, 7 6, 6, 50, 0 8, 7,8 0,, ,, 8,6,5, 5,, 5, 65 76,7 0,, 0,5, 6,5 6, ,7 5,,5,6,6,8 65,5 8, 6,8 7,8 8,, 6,8 65 0,6 7,7 6 7, 6, 6,6 7, , 7,6, 07 5, 0,7 5, ,5, 8,, 6,, 7, ,8, 7, 5 7, 8,7,6 00, , 5,,,7 8,6,6,7,5,5, 0,7 8, 5,7 0,, 8,7,6,7 6,6,6 66,5 6, ٤ ٢
