摘要:
2022年7月至12月,全球共生成55个热带气旋,其中北半球生成51个,较常年同期偏少0.5个;南半球生成4个,较常年同期偏少1.9个。西北太平洋热带气旋平均生成位置(20.6°N,136.5°E)较常年平均(16.1°N,136.3°E)偏北4.5个纬距。9月至10月,飓风"伊恩"重创美国、"罗斯林"严重影响墨西哥,台风"轩岚诺"、"梅花"、"南玛都"、"尼格"与"奥鹿"侵袭西北太平洋沿岸多国。西北太平洋9月至10月热带气旋多发,较常年偏多3.5个。9月至10月西北太平洋17°N~28°N、130°E~145°E附近大气低层受气旋式辐合环流控制,且气旋式辐合较常年偏强,海温较气候平均偏高0.5~1.0℃,为西北太平洋热带气旋多发创造了有利条件。
Abstract:
From July to December 2022, a total of 55 tropical cyclones were generated over the global oceans,of which 51 tropical cyclones were generated in the Northern Hemisphere(0.5 less than the climatology for the same period), and 4 were generated in the Southern Hemisphere(1.9 less than the climatology for the same period). The average generated position(20.6°N, 136.5°E) of tropical cyclones is 4.5 latitudes northward from the climatology(16.1°N, 136.3°E) over the western North Pacific. In September and October, hurricane IAN severely hit the United States, hurricane ROSLYN seriously affected Mexico. Typhoons HINNAMNOR, MUIFA, NANMADOL NORU, and NALGAE affected many countries along the coast of the western North Pacific. Besides, tropical cyclones frequently occurred in the western North Pacific, with 3.5 more than usual from September to October. The lower layers of the atmosphere near 17~28°N, 130~145°E in the western North Pacific were controlled by cyclonic convergence circulation in September With a positive bias than usual and the SST was 0.5~1.0℃ higher than the climatology, which created favorable conditions for the frequent occurrence of tropical cyclones in the western North Pacific.
