Distribution of the Contemporary Precipitation Regime and the Impact of Climate Change on it within the Territory of Azerbaijan

Nazim Shakar Huseynov1 *, Jamal Surxay Huseynov2

The regularities of the contemporary distribution of the precipitation regime within the territory of Azerbaijan were researched in the research paper. The perennial tendency of the precipitation regime was determined using the rainfall observation data for the years between 1961 and 2020 in the conducted research. Based on the obtained results, a state-of-the-art precipitation map was compiled for the country. At the same time, the dynamics of the precipitation regime during the period 1961-2020, as opposed to the period 1881-1960, were evaluated. The research period was divided into two half-periods, namely 1961-1990 and 1991-2020, and the internal tendencies were analysed. The results of the investigation indicate that although the amount of the precipitation region underwent a downward trend across the country, the number of stations with a statistically significant decrease is small. Compared to the years 1881-1960, the amount of precipitation has decreased throughout the country. Moreover, the average annual temperature in the country increased by 0,8°C from 1991 to 2020. This indicator is the same period between 1961 and 2020 compared to the period between 1881 and 1960. In order to conduct research, mathematical-statistical and cartographic methods were used.
