ABSTRACT. – The Deficit of Humidity and the Associated Risks in the Reghin Hills. Droughts are atmospheric phenomena of complex risk, due to the reduction or even to the absence of rainfall, characterized by a deficit of humidity (rainfall, underground waters, surface leakage) which can affect the geographical covers over a long period of time. This paper presents an analysis of the pluviometric conditios in the Reghin Subcarpathians with a special view of the periods of pluviometric deficit. In order to identify the periods of pluviometric deficit, in a first stage, we analysed the main parameters which define the pluviometric conditios (the annual, the seasonal and the monthly variations and deviations, the degree of assurance of the different quantities of rainfall), and in order to emphasize the intensity and the caracter of the periods showing a deficit we calculated the Standard Rainfall Anomaly, the Angot index, the analysis of the negative deviations in the rainfall quantities with the help of the Hellmann method and the Martonne aridity index.
Keywords: quantity of rain-fall, excess of humidity, natural risks, vulnerability.
