Abstract

Based on data from the Remontnoe weather station located in the Eastern natural and agricultural zone of the Rostov region, the seasonal and annual dynamics of the average temperature and precipitation have been evaluated for the period of 1961–2020, as well as the dynamics of hydrothermal conditions expressed by the De Martonne aridity index. A significant trend to the growth of the average annual temperature and a trend to the growth of annual precipitation were observed for the studied period. A significant trend to an increase in the average seasonal temperature was observed for all seasons except autumn, for which a positive trend was registered. A downward trend in precipitation was revealed for summer seasons, whereas the opposite trend was observed for other seasons. The annual hydrothermal regime was characterized as moderately to slightly arid in 75% of cases. Moderately arid conditions also dominated in the spring (43%), summer (55%) and autumn (47%) seasons. The observed seasonal changes in the temperature and precipitation regimes during the studied period resulted in a shift in the character of hydrothermal conditions. Winter and summer seasons were characterized by a tendency of a hydrothermal regime shifting towards greater aridity, whereas spring and autumn were characterized by the opposite trend. In the case of the annual evaluation interval, a shift of the hydrothermal regime to a greater humidity was observed simultaneously with the increased precipitation. Thus, based on the revealed annual trends, we can conclude that the Remontnoye weather station was characterized by humid warming during 1961–2020.

1961-2020 年罗斯托夫州东部自然农业区水热条件的季节和年度动态

摘要

根据位于罗斯托夫地区东部自然和农业区的 Remontnoe 气象站的数据，评估了 1961-2020 年期间平均气温和降水的季节和年度动态，以及热液动态由 De Martonne 干旱指数表示的条件。在研究期间观察到年平均气温增长的显着趋势和年降水量增长的趋势。除秋季外，所有季节均观察到平均季节性温度呈显着上升趋势，秋季呈正趋势。夏季降水呈下降趋势，而其他季节则呈相反趋势。在 75% 的情况下，年度热液状态的特征是中度至轻微干旱。春季 (43%)、夏季 (55%) 和秋季 (47%) 季节也以中度干旱为主。在研究期间观察到的温度和降水状况的季节性变化导致热液条件特征发生变化。冬季和夏季的特点是热液状态有向更干旱转变的趋势，而春季和秋季的特点是相反的趋势。在年度评估间隔的情况下，在降水增加的同时观察到热液状态向更大湿度的转变。因此，根据揭示的年度趋势，
