The issue of knowing and highlighting the spatio-temporal variability of the hydrothermal regime during the warm period of the year, in the context of regional climate change, is becoming more current and very important. The great climatic variability attested in the last decades is accompanied by great material damages. Thus, in the years 2000-2018, practically the absolute maximums exceed the value of 36˚C, the absolute maximum being reached in 2012 (42.4˚C). The absolute maximum in the first decade of the 21st century (2000-2009) is 29.5˚C, and in the thermal one the amplitude is 63.7˚C compared to 51.2oC in the last decade of the last century (1989-1999). In the second decade (2010-2018) the absolute maximum temperature reaches values of 42.4˚C. The thermal amplitude is 62.5˚C. Such climate variability also occurs in the precipitation regime. Frequent alternations of dry periods with periods accompanied by torrential rains, attested mainly in the summer months, can directly influence the productivity of agricultural crops and, respectively, the income of the rural population in the republic. Also, increased variability in air temperature and the amount of rainfall can destabilize arable land, with the risk of flooding and the danger of landslides. Thus, the material damages caused by the torrential rains of the hot semester of the year on the territory of the republic for the period 1997-2018 amounted to 5256.9 billion lei, determined by large amounts of water, increased intensity and high frequency of these rains. The value of the damages caused by the torrential rains in the months of the warm semester of the year varies significantly from one month to another, both at the level of the republic and for each administrative district being determined by the variation of the parameters of torrential rains.
