Abstract
The Mediterranean cyclones – the role in ensuring water resources and their potential of climatic risk, in the East of Romania. The mean altitude of Romania’s landforms is 420m and the mean annual amount of precipitation is 640mm. The direction of the general atmospheric circulation is everywhere from west to east and that is why in the territories situated to the east of the Eastern Carpathians, in the area of Moldavia, the mean annual amount of precipitation is 560mm. In Romania, the percentage of the precipitation generated by the Atlantic and Mediterranean cyclones is 80%, and the rest of 20% are produced in local circuits (Ujvári, 1972). Due to the obstacle created by the Eastern Carpathians, in Moldavia the pluvio-genetic potential of the west and north-west circulation is very much diminished. The Mediterranean cyclones ensure an important percentage of the total amount of rainfall. For one month a year the studied area is under the influence of these cyclones. Although the distance to the Adriatic and Aegean Seas is only of 700 km, the mountain landforms of the Balkan area diminish the pluviometric capacity of these cyclones. This paper approaches mainly the effects produced by the Mediterranean cyclones that follow the 3a, 4a and especially 3b path (Weather in the Mediterranean, 1962), Vc (Van Bebber), VII (Kriceack, Zverev), and also according to the Romanian researchers (Doneaud, 1957, 1958; Şorodoc 1962; Pribisch, Bordeianu 1966; Grimani, Besleagă, 1976, and others). The Mediterranean cyclones that follow a retrogressive rout high above the Black Sea and to the north of it, have also been studied. The most important events of climatic risk produced by the Mediterranean cyclones in Romania, have been analysed (1970, 1991, 1993)
