The radar observations along the vertical of precipitation in stratiform clouds are compared with the theoretical growth rates of ice crystals in such clouds. The analysis indicates that no liquid water exists in these clouds at levels above about −5°C. The variation of signal strength from the −3°C level through the ‘bright band’ and the drop‐size distribution in the rain measured at the ground can be satisfied by reasonable assumptions concerning the coalescence of ice crystals.
