Description
For the investigation of geographical, monthly, seasonal, and annual distributions of
aridity and its annual trend in the region of the Central and Southern Pannonian Basin (CSPB),
which includes the territories of Hungary and Vojvodina (Northern Serbia), the De Martonne Aridity
Index (DMAI) was used. The DMAI was originally calculated from a total of 78 meteorological
stations with the maximum available time series of climatological data in three cases: 1931–2017 for
Hungary; 1949–2017 for Vojvodina; and 1949–2017 for Hungary and Vojvodina jointly. The Palmer
Drought Severity Index (PDSI) was used to control the DMAI results. Temperature and precipitation
trends were also investigated to understand their eects on the aridity trend. Three aridity types
are distinguished on the annual level, five on the seasonal level, and four on the monthly level.
The annual aridity had no trends in all three periods. It seems that aridity can be considered a more
stable climate indicator of climate change than the temperature, at least in the CSPB.
