State

Key message
Bad

In the period 1961-2012 is noted a rising trend absolute maximum temperature and the minimum absolute temperature, reflecting global warming. Increasing the number of hot days, we are seeing a greater frequency of extremely hot days with daily maximum temperature above 35 ° C. The number of ice days show a downward trend. More than temperature are variable rainfall (thunderstorms, hail). In the last two decades, we are seeing a severe drought that may occur in successive years, and extensive flooding. The catastrophic floods and droughts can be facing in the same year.

The indicator shows annual extremes: the minimum and the maximum air temperatures, the number of days with temperatures above and below the selected threshold, and the maximum snow cover depth in six places across Slovenia. Characteristics of heavy precipitation and storms are described in words.
