Abstract:By means of Doppler radar and Wind Profiling radar data, along with weather reports in August, 2010 in Chengdu and July and August 2011 in Beijing, an analysis is made of the abilities of different radar to identify the corresponding weather phenomena. The comparative analysis indicates: (1) when there is weaker precipitation, the correlation between horizontal wind directions and speeds obtained by the two kinds of radar is very good within the heights of 300 to 2100 meters, and the wind direction correlation coefficient is 0596, and that of wind speeds is 0736, which should be considered together for forecasting; (2) under the condition of heavy rainfall, the correlation between horizontal wind directions and the speeds obtained by the two kinds of radar is good at different altitudes, especially from 300 to 2100 meters, and the correlation coefficient of the wind directions is 0508, and that of wind speeds is 0573The wind vector products of wind profiling radar give more details; (3) in overcast weather, the correlation between horizontal wind directions and speeds obtained by the two kinds of radar is better at lower levels than that at higher levels; (4) under sunny conditions, the wind profiling radar is more suitable for weather forecasting and monitoring.
