Strange typhoon "hippocampus" path?

1 104 Tropical Storm Hippocampus was formed in the afternoon of June 18. After entering the South China Sea on the 20th, it was obviously influenced by the control and guidance of atmospheric circulation, and its moving path was unstable and changeable. It suddenly landed north at noon on the 23rd and then retreated to the South China Sea. After landing again in Zhanjiang at night, it crossed Leizhou Peninsula and entered Beibu Gulf today. At present, it is moving to the north of Vietnam, and the central wind speed is strengthened to 20. ?

The moving path of "hippocampus" is mainly that its kinetic energy is relatively small. Yesterday, the Qinghai-Tibet Plateau was pressed south by cold air, so the "hippocampus" could not go north and was forced to return to the South China Sea and move westward into the Beibu Gulf, which had nothing to do with the double typhoon effect.
