Correlation coefficient of 0.81 between Sava River flow through Zagreb and precipitation in Ljubljana points at dominant significance of precipitation. In the warmest months Sava flow is very much dependent on evapotranspiration. Sava River flow has downward trend, and two intervals can be sharply distinguished: 1926-1959 and 1960-1995. That is the result of the identical precipitation trend at the Upper Sava. There is the trend of atmospheric pressure rise in the entire observed period. "Precipitation continentality" is characterized by change of trend. Share of "summer" precipitation has been declining since 1960.

Abstract. By the combination of land and sea data the author came to the conclusion that the duration of the Middle and Upper Pleistocene glacial ages was of the same order of magnitude. The temperature of the glacial ages was not exactly the same, but each younger glacial age was a little colder than the preceding one. Similarly, each younger interglacial age was a little cooler than the preceding one. Bringing together all known data the complex Pleistocene generalized paleotemperature curve is constructed showing the main trend of the temperature evolution from Mindel glacial until now, spanning the time of about 400,000 years.
