Comparative Analysis of Up-Air Sounding Data between L-Band Radar with TK-2GPS Weather Modification Rocket

Using the Up-Air Sounding Data of TK-2GPS Weather Modification Rocket,Compared with the data of L-Band radar. Analysis results show that TK-2GPS rocket detectors can relatively accurate describe the variation characteristics of temperature,humidity,air pressure,wind direction,wind speed and other meteorological elements. Two kinds of temperature profile are very consistent. And the TK-2GPS rocket sounding data can clearly describe the temperature inversion characteristics. There is a certain deviation between two kinds of humidity,also found in the dew-point temperature Wind speed and direction data,etc. This deviation may be associated with the different time of two kinds of sounding data. The vertical profile of wind speed and direction of TK-2GPS rocket have mutations,which may be associated with stability and sensitivity of the detecting instrument.
