Abstract

This paper assessed aridity and humidity conditions in Bačka (north Serbia) in the period 1949–2018. The assessment was based on the analysis of air temperature and total precipitation from 5 meteorological stations. Spatio-temporal changes were determined based on aridity indices, statistical and interpolation procedures. The Mann–Kendall indicates no statistical significance in aridity trends at most stations. The annual value of the Lobova index indicates arid conditions. Monthly values of the De Martonne index (I_DM) do not show a statistically significant positive or negative trend, except for May, September to December. The annual values of the I_DM indicate diversity of aridity conditions with a statistically significant positive trend on annual level only at one station (Sombor). Dry and wet years are equally distributed based on Rainfall Anomaly Index (RAI). The 2010 belongs to extremely wet category while the 2000 stands out as extremely dry. Statistically significant positive aridity trend was observed for RAI on annual level for two stations (Palić and Sombor). According to interpolation technique, annual and seasonal values of the I_DM belong to humid and semi-humid conditions. The spatial variability of the RAI is between normal and slightly dry. The Lobova index shows different patterns of aridity. This study provides insight into the dynamics of aridity, and its results can be used in planning and implementing climate change adaptation measures. Since agricultural productivity is highly dependent on aridity and drought conditions, agricultural activities face numerous challenges. Therefore, the presented results can provide a solid basis for designing and implementing adaptation strategies and interventions on a regional scale in order to mitigate the impacts of climate change and aridity on agricultural production in the studied region.

塞尔维亚ba ka干湿指数时空变化特征

本文评估了1949-2018年ba ka（塞尔维亚北部）的干旱和湿度条件。该评价是基于对5个气象站的气温和总降水量的分析。基于干旱指数、统计和插值程序确定了时空变化。Mann-Kendall显示大多数站点的干旱趋势没有统计学意义。Lobova指数的年值表示干旱条件。De marton指数（IDM）的月度值除5月、9月至12月外，没有统计学上显著的正或负趋势。IDM的年值反映了干旱条件的多样性，只有一个站点（Sombor）在年水平上呈显著的正趋势。根据降雨异常指数（RAI），旱涝年分布均匀。2010年份属于极湿年份，而2000年份则属于极干年份。paliki和Sombor两个站点的RAI在年水平上呈显著的正干旱趋势。根据插值技术，IDM的年值和季节值属于湿润和半湿润条件。RAI的空间变异性介于正常和略干之间。Lobova指数显示了不同的干旱模式。该研究提供了对干旱动态的深入了解，其结果可用于规划和实施气候变化适应措施。由于农业生产力高度依赖干旱和干旱条件，农业活动面临许多挑战。因此，研究结果可为设计和实施区域尺度的适应策略和干预措施提供坚实的基础，以减轻气候变化和干旱对研究区域农业生产的影响。
