摘要:
2022年1月至6月，全球共生成29个热带气旋，其中北半球生成8个，较常年同期偏少1.5个；南半球生成21个，较常年同期偏多1.6个。西南印度洋1月下旬至2月中旬气旋群发；西北太平洋生成频数较常年偏少1个。西南印度洋"安娜"、"巴齐雷"等总计5个气旋登陆，重创马达加斯加、莫桑比克和马拉维等多国，西北太平洋"鲇鱼"重创菲律宾，东北太平洋"阿加莎"严重影响墨西哥。西南印度洋10°~20°S大气低层气旋式辐合较常年偏强、海温较常年同期偏暖，为热带气旋群发创造了有利条件。拉尼娜事件影响下的热带印度洋、西太平洋海温异常偏暖以及西北太平洋副热带高压偏强、范围偏大、位置偏南，抑制了西北太平洋台风生成源地的热带对流活动。
Abstract:
From January to June 2022, a total of 29 tropical cyclones generated over the global oceans, including 8 in the northern hemisphere(1.5 less than climatology), and 21 in the southern hemisphere,(1.6 more than climatology). Tropical cyclones occurred in groups from late January to mid-February over the Southwest Indian Ocean. Less typhoon formed in the western North Pacific. 5 cyclones(including "Ana" and "Batsirai") made landfall and devastated Madagascar, Mozambique, and Malawi. Tropical storm"Megi" generated in the western North Pacific hit the Philippines. Hurricane"Agatha" generated in the eastern North Pacific severely affected Mexico. The 10°~20°S intense low-level cyclonic convergence in the southwestern Indian Ocean was stronger than normal, together with a warmer SST, creating favorable conditions for grouped occurred tropical cyclones. Under the influence of the La Ni? event, the abnormally warmer SST in the tropical Indian Ocean and the western Pacific and a stronger, larger and southerly subtropical high in the western North Pacific inhibited the tropical convection activities in the source of typhoons.
