The Impact of Climate Change on the Precipitation Regime in Bosnia and Herzegovina

Abstract

For the study presented below, observations from four stations in B&H (Sarajevo, Mostar, Tuzla and Bjelašnica) were considered. In order to examine differences from the past, and thus the progress of climate change, and since the station in Sarajevo has had unremitting terms from 1901 until now, data for the periods 1901–2006 and 1951–2006 are used for this station whereas for the other stations, only data from the period 1951–2006 are used. Maximum daily precipitation, i.e. one daily, two daily, three daily and five daily maximum precipitation incidents are studied. As well, maximum 10- and 5-year values and short-term rain for the above periods are examined. It is interesting to join the linear trends in these periods and thus ascertain increases in values, while at the same time there has been an increase in periods of drought. The situation is only different at the Bjelašnica station, where there has been a decrease in these values. Such results are especially startling for the year 2007, when through April-September, more extreme warm and extreme cold periods were observed, followed by drought and extreme precipitation events.
