ESTIMAREA DEFICITULUI DE SATURAȚIE ȘI A PREJUDICIILOR MATERIALE CAUZATE DE PLOILE TORENȚIALE ÎN EXCES

Abstract

Warm season’s hydrothermal regime’s knowledge is extremely important from the point of view of applied decision-making in the areas of agriculture’s sustainable development. Climatic variability of the past few decades determines a continuous estimation of warm season’s hydrothermal regime, aiming to ensure the optimal supply of heat and humidity resources for the agricultural plants. The present article analyzes the thermal and humidity regimes during the summer months, the period during which the major growth and intensive development of the agricultural plants is taking place, allowing us to identify the particularities of the said regimes spatio-temporal distribution The estimation of the concomitant evolution of the saturation defcit (mb) with the number of the dry days demonstrate a rising trend for the both of these climatic components, starting with the 80s of the XXth century; the most essential values are observed on almost entire territory of the republic in the end of the frst decade of the XXIst century. also in this period we observe the highest material losses caused by the excesses of atmospheric precipitations. The value of the losses caused by the torrential rains during the warmest semester of the year varies signifcantly by the month, both at the republic’s level and at the level of the separate region, being determined by the variation of the main parameters of these rains. Thus, humidity defcit and pluviometric excess had occurred regularly in the regional climatic system and are caused by the changes in the actual global climate.
