The main characteristics of the general atmospheric circulation in the spring (from March to May) of 2017 are as follows. There was one vortex center in the North Hemisphere, which located at the Arctic Ocean. The westerlies of middle high latitudes had five waves. The surface cold high pressure was stronger than normal year, so cold air activities were more frequent in March. In April, the general atmospheric circulation was adjusting from latitudinal pattern to meridional pattern. Cold air was weaker. Northeast cyclone was obviously strengthened; the intensity of cold air strength was same with the warm air, so the numbers of cyclones which moved into the sea increased in May. In spring, there were sixteen gale processes in inshore. There were seven wind processes were produced by cold air and one gale process was produced by cold air and extratropical cyclone and four gale processes were produced by cyclones which moved into the sea and three gale wind processes produced by northeast cold vortex and one thunderstorm gale process produced by severe convective storm. There were eight rough sea wave processes above two meters and six sea fog processes in spring. one process occurred in March, two processes occurred in April and three processes occurred in May. There were one typhoon Muifa and one tropical depression (TD) over western north Pacific and south China Sea. In addition, there were fifteen tropical cyclones (TC) including one TC was over the Atlantic Ocean and one TC was over East Pacific and five TCs were over South Pacific, six TCs were over South Indian Ocean and two TCs were over North Indian Ocean.
