The Moldavian Plain, located in the North-Eastern part of Romania, has a temperate-continental climate with a nuance of excessivity in the precipitation regime. This paper aims to analyse droughts in the Moldavian Plain for the period 1961-2010, by using a classical method - the de Martonne Aridity Index, and two other less known indices developed in Romania and the Republic of Moldova. Among these indices, the Dry Spells Index demonstrates a increasing frequency of dry years in recent decades.
