Abstract: Based on the remote sensing data from the meteorological satellite and new generation weather Doppler radar, a strong convective storm rain case on July 22, 2008 was analyzed in the Huaihe River basin, and the similarities and differences of two remote sensing methods were discussed. The result indicate that the large scale weather background could be observed on the satellite cloud image in spite of its resolution is low compared with that of weather radar. The evolution trend of convective system could be analyzed in terms of the locations of contour line of Tir=Twv. The radar echo intensity has higher temporal and spatial resolutions, so the small scale features of convective system and radical velocity in the different heights could be observed in terms of Doppler weather radar. Two methods could assist each other, so more effective information could be obtained if both are combined.
