Why does Typhoon Plum Blossom appear in the north?

The path of typhoon mainly depends on the turning airflow at the western edge of subtropical high. When the plum blossom was just born, the turning flow was very weak, so the movement speed of the plum blossom was very slow, and it basically moved northward. On August 3, as the subtropical high extended westward, the path of Meihua began to shift westward. However, after Meihua entered the East China Sea, the subtropical high formed a north-south blocking structure, guiding typhoon Meihua journey to the south. Because the subtropical high is located to the east, "Meihua" has never landed on the eastern coast of China; Due to the lack of southwest monsoon supply, "Meihua" can not continue to strengthen. The farther north, the lower the sea surface temperature and the weaker the intensity. On August 8, as the subtropical high moved eastward again, Meihua finally turned to the northeast and landed on the northwest coast of Korea at around 18: 30. After landing, Meihua continued to move to the north, and entered Changchun, Jilin on the morning of August 9, and gradually dissipated.

The average temperature in the coastal areas of Shandong and Liaoning is the highest in August, so it is most likely that the typhoon will affect Shandong and Liaoning northward in August.

The path of "Meihua" belongs to the eighth category of typhoon abnormal path, that is, high-latitude frontal landing. This typhoon has been moving to the northwest since its formation and landed in Shandong, Liaoning and western Korea. This path is stable, but the probability is small. In August this year, the subtropical high formed a north-south block structure. Influenced by the turning airflow at its western edge, Meihua rarely landed at high latitudes. In June, the No.5 typhoon "Miller" also made landfall in Chengshantou, Shandong Province, because of the north-south block structure formed by the subtropical high. However, the water temperature in August is higher than that in June, so the intensity of plum blossoms is stronger and the landing position is farther north. The following is the path map of Typhoon Meihua.
