Mean annual rates of the number of days with precipitation and thunder are shown in figure
27. It can be observed that there are two maximums of precipitation annually, in spring
months (March, April) and autumn (October, November, December). On average it amounts
to about 100 days a year, whereby the greatest number is of days with precipitation between
0.5 and 1 litre per square metre. The number of days with certain quantity of precipitation
(ranging from 0.1 to 50 mm) is shown in figure 28. The total annual quantity of precipitation is
about 1080 mm on average.
Precipitation is the parameter which is measured once a day at 7 a.m. Consequently, the
quantity of precipitation refers to the total precipitation which is registered in the period of 24
hours. In about 10% of cases it is above 20 litres per square metre, while about 3 days a
year can be expected to have very heavy precipitation with about 50 l/m 2 and more.
