 The precipitation leaves the grid volume immediately if the threshold of the liquid water content 
 $\overline q_{l_{\mathrm{crit}}}=0.5\,\mathrm{g/kg}$ is exceeded. Hence, evaporation of the rain drops does not occur.
-$\tau$ is a time scale with a value of 0.001\,s.

 The influence of the precipitation on the temperature is as follows:
