Abstract

Maximum daily rainfall amounts recorded in the South Dobrogea in 1965-2000 exceeded or equaled the average amount of seasonal rainfall. Thus determine the causes are either due to rain or strong local convection passage of atmospheric fronts. Unlike the showers of rain, torrential rainfall type can sometimes give large amounts of water in short intervals, but may continue longer with a higher intensity and their duration increases. This type of precipitation occurring during summer (especially july and august), are likely front and usually occur the day. Fundamental processes that lead to the development of cloud formations, capable of producing large amounts of precipitation are convection and turbulent exchange of air masses inside. To illustrate these these maximum amounts of rainfall (floods generators) were analyzed records from thirteen precipitation stations and the seven weather stations in South Dobrogea, during 1965-2000.
