    356356The precipitation leaves the grid volume immediately if the threshold of the liquid water content
    357357$\overline q_{l_{\mathrm{crit}}}=0.5\,\mathrm{g/kg}$ is exceeded. Hence, evaporation of the rain drops does not occur.
    358 $\tau$ is a time scale with a value of 0.001\,s.
     358$\tau$ is a retarding time scale with a value of 1000\,s.
    359359\newline
    360360The influence of the precipitation on the temperature is as follows:
