ABSTRACT
Torrential rains fall during the warm season due to the intensification of the Azores Anticyclone activity, and the Atlantic and Mediterranean cyclone. Fundamental processes that lead to the development of cloud formations capable of producing large amounts of precipitation are, as it is known, convection and turbulent exchanges inside air masses. Summer rainfall in Dobrudja is of frontal nature and usually occurs during the day as showers. The correlation curve between the distance to the Black Sea of the pluviometric points and the maximum daily amounts of precipitation (24 hours) fallen during each of the summer months has a similar aspect to that of the average precipitation quantities on the Dobrudja territory during the warm period of the year (April-October) (Mihăilescu, 2001). Maximum amounts of rainfall (24 hours) decrease gradually from the land, from a distance of 30-35 km,with a tendency to reach the lowest values on the Black Sea littoral. The significant correlation coefficient between the distance to the sea and the maximum daily amounts of precipitation (24 hours) confirms their obvious influence on precipitation distribution in Dobrudja
