A Study of Automatic Tacking Mesoscale Convective Systems with Improved Area-Overlapped Method
用改良的面积重叠法自动跟踪中尺度对流系统的试验研究

The activities and evolvements of mesoscale convective systems (MCSs) is one of the mostly factors which heavy rainstorm arise from Many scholars have increased the interest in the study on MCSs from these years However, the progression on studying activities and evolvements of MCSs is restricted by the technology of automatic identifying and tracking MCSs The thesis first introduces area overlapped method of automatic tracking MCSs Then aiming at its shortage, the area overlapped method is improved Using improved based method, the experiments are performed with data of MCSs over the Tibetan Plateau and its surrounding area in summer of 1998 The experiments show that the precision of tracking MCSs is about 80% with improved based area overlapped method, it is increased more ten percents than before improvement
