Abstract EN
The intensity of precipitation extremes is expected to increase as the climate warms and it may cause floods and increase erosion.
From the Clausius-Clapeyron relation (CC) it follows that the maximum moisture content of the atmosphere increases by approximately 7% per degree as temperature rises.
However, the increases in observed hourly precipitation extremes of approximately two times the CC relation were described recently.
This super CC scaling is attributed to the increased prevalence of convective rainfall and decreased prevalence of stratiform rainfall as temperatures increase.
We carried out the disaggregation of precipitation into prevailing stratiform and convective component on the observational data from the Czech Republic for 1966–2006.
Then, we analyzed trends in characteristics of disaggregated events and assessed correlation of precipitation intensities with daily mean temperature.
The results suggest the increasing trend of convective precipitation in summer.
The scaling for total rain events is steeper than for the events with prevailing convective component and for the events with prevailing stratiform component.
It is a result of mixing of the two storm types.
At higher temperature the events with prevailing convective component prevail and vice versa.
