Abstract:
The distribution of cloud top temperature is estimated base on the echoes at the top height of the Precipitating stratiform cloud system measured by the 713 type weather radar in Hebei province. The results show thai from 57 percent to 70 percent of cloud top temperature are seedable in the stratiform clouds according to proposed seedability index of cloud top temperature by Grant. In the sametime,based on different attenuated dB values of radan echoes (?Z/?H),the growth case of snow particles with different temperature layers variation is analyzed.
