PRELIMINARY ANALYSIS OF RAINFALL ESTIMATE UTILIZING DUAL LINEAR POLARIZATION RADAR

In the paper,Asp(approx imation after sor tand pair) method have been put forward forget parameters of rainfall estimate.The paper use 1314 samples of radar and 17 precipitation stations at 1993-1994.This method make up the defect of linear regression and raise the precision ofarea rainfall estimate.Having analysed the errors,have gained the result:When estimate area precipitation more than 1 000km2 using dual linear polarization radar,the error will redeced to under 10% probably,it is better more than conventional radar;The difference between estimate formulas of dual linear polarization radar can over look;The method of estimate area rainfall in classified parameters is only effective using conventional radar.
