Abstract:

The agricultural sector has a major social and economic importance for the Republic of Moldova. The aim of the study is to analyze the probability of the occurrence of late frosts on the territory of the Republic of Moldova for the period of 2005-2020, a period in which, from a synoptic point of view, the most obvious effects of climate change were observed on the territory of the Republic of Moldova. Knowing the probability and risk of occurrence of these hazardous climate phenomena is important because it helps farmers decide what, when and where to plant to achieve the maximum possible crop yields. The study aims to map these dangerous manifestations throughout the territory of the Republic of Moldova. Meteorological data regarding the date of the last frost in the air were collected and selected from the archive under the State Hydrometeorological Service. Also, the factual material, regarding the date of the stable passing of the air above 10°C, were calculated in the Climatology and Environmental Risks laboratory of the Institute of Ecology and Geography. The main effort was to analyze temporally and spatially the occurrence of frosts that occurred after the stable passage of air above 10°C. As a result, maps representing the spatial distribution of these frosts were modeled. The temporal distribution was represented in the form of tables. The obtained results will be able to be extended for analysis on physicalgeographical regions and territorial administrative units. The spatial and temporal trends in freeze warnings may be of interest to any number of scientists with applied climatological interests.
