Abstract:Based on the data of mesoscale weather stations and the radar mosaic, the gales in two typical strong convection weather processes in June, 2009 are analyzed. The data come from the mesoscale experiment base of the key laboratory of Anhui Province. One process occurs on June 3-4, and the other process on June 14. The horizontal features and the characteristics of Doppler radar mosaic are studied. The two weather processes are compared. The results are as follows. (1) The 8~10 level gale number in the first severe convection process is less than that in the second process. The gales in the first process appear mostly in areas along Huai River and Northern Huai River. The gales in the second process appear mostly in areas of Anhui Province. The distribution range of the second process is much bigger than the first process. (2) The wind speed in the first process has a peak value, and in the second process has 2 peak values in the north area. (3) The first process is mainly created by radar echo once, and the second process is created by radar echo twice. The first process has one echo mergence phenomenon, and the second process has two echo mergence phenomena. The convective cell is enhanced after the mergence. Motion direction of the two processes is the same, that is, east by south. The intensity of the maximum radar echo is more than 55dBz.
