Analysis of Wet Periods in Vojvodina Province Using Standardized Precipitation Index

Abstract

Summary In this study, wet periods were analyzed using the Standardized Precipitation Index (SPI) on timescales of 3, 6 and 12 months (SPI3, SPI6 and SPI12) at eight stations in Vojvodina Province during the period 1971-2019. The obtained results show that there were very wet years in the observed period, so that regular maintenance of drainage channels is of great importance. Also, in order to illustrate the wet periods for the area of Vojvodina, maps for a timescale of 6 months (SPI6) were made for the vegetation season (April-September) of 2010. By analyzing the maps, it can be concluded that there were four categories of humidity conditions occurring in the observed period – from normal humidity conditions through moderate to very humid and extremely humid conditions.
