    VALURILE DE CĂLDURĂ ÎN ULTIMELE DOUĂ DECENII ÎN SUDUL REPUBLICII MOLDOVA
    (CEP USM, 2024) Domenco, Rodion; Boian, Ilie
    The maximum temperatures in the warm period of the year register obvious upward trends. In the south of the Republic of Moldova, according to climate evolution scenarios, temperature is the main climatic element affected by climate change. To determine the duration, intensity and number of heat values, we used one of the methods often used in climatology – the percentile method. Thus, we found that the number of cases with maximum temperatures above 30°, 35° and 40°C recorded in recent years is higher than the multiannual average. The duration of heat waves has increased, the maximum values moving towards August, and the period of occurrence of hot periods has extended until September.

    RISCUL VALURILOR DE CĂLDURĂ DIN ULTIMELE DOUĂ DECENII PENTRU MOLDOVA ÎN CONTEXTUL SCHIMBĂRILOR CLIMATICE REGIONALE
    (CEP USM, 2024) Boian, Ilie
    In the Republic of Moldova, practically as in all of europe, climate changes are visibly manifested in recent decades by increasing the frequency, intensity and duration of heat waves (for example, the episodes of 2007, 2012, 2015, 2020, 2022, 2023), being accompanied by an increase in the intensity of short-term precipitations. For the realization of the present study, the factual data collected from the archives of the state institutions of the Republic of Moldova were used: the state Hydrometeorological service (sHs); national Bureau of statistics (nBs). The mentioned data were systematized, processed, interpreted graphically and cartographically, with the use of statistical programs - statgraphics, Instat Plus and QGis, in accordance with the proposed objectives. In the Republic of Moldova, during the last 23 years, the number of cases with absolute maximum temperatures was very high. In all these years, temperatures ≥ 33.0°C were recorded, including values ≥ 40.0°C. Heat waves influence all sectors of the economy, but agriculture remains the most vulnerable, and the impact on it is more signifcant today, because climate changes and variability are becoming more and more pronounced.
