In the Northern Hemisphere, the general atmospheric circulation in autumn (from September to November) 2022 is characterized by a dipole mode of polar vortex and 5-wave circulation in the middle and high latitudes. In Eurasia, the circulation pattern of the westerly wind belt is straight without significant ridges or troughs. Cold air is weaker than the historical average, and tropical cyclones are frequent between September and October. Among the 14 gale events above Beaufort scale 8 over offshore areas of China, 5 are produced jointly by cold air and extratropical cyclones, 5 jointly by cold air and tropical cyclones, two by tropical cyclones, and two by cold air. There are 13 tropical cyclones in western North Pacific and the South China Sea, while 22 tropical cyclones are named in other oceans. There are 80 days of rough sea wave events with wave height greater than 2.0 m, accounting for about 88% of the total days of autumn. In autumn, the sea surface temperature (SST) over China’s offshore waters decreases month by month, and the SST in the northern (southern) sea areas is lower (higher) than the climatological normals.
