         ABSTRACT. - Droughts in the Republic of Moldova. This study is an attempt to determine the climatic conditions that lead to different kinds of droughts, their time and space distribution and the level of impact on the agricultural and industrial sectors. The droughts are specific for the climate of the Republic of Moldova and are caused by non-uniform time and space distribution of the precipitations along with high air temperatures. The analysis of droughts for a more that a century has shown that the frequency of droughts is becoming higher since 1980. The analyses of droughts by affected area and by seasons have shown that the catastrophic and big droughts occur in spring, extreme droughts occur in summer and catastrophic droughts in autumn. In this study is mentioned that in the last two decades catastrophic droughts occurred in 1994, 2000, 2003 and 2007. The 2007 drought in the Republic of Moldova started in autumn 2006. The amount of precipitations in the period 01.09.2006 06.08.2007 constituted 50-70% of climatic norm. The situation became more severe in May-June 2007, as the quantity of precipitations made up only 30% of norm and the average air temperature was 21 23C that is 3 - 4C higher than the norm. The catastrophic 2007 drought affected more than 80% of the territory of the republic and is the most severe drought registered for the whole period of instrumental measurements. Taking into consideration the main agrometeorological indices, the 2007 drought was more acute than the 1946 drought, and caused national economy losses of 1 milliard American Dollars.
