Abstract: | The main characteristic of Typhoon Doksuri (2305) are summarized, and the difficulties in its forecast are also analyzed. The main conclusions are as follows. (1) Typhoon Doksuri is characterized by its strong landfall intensity, which, for the year 2023, is the strongest typhoon that makes landfall in China by October. Sustaining on land for a long time after landing, it breaks the historical records of wind and precipitation at multiple stations in places such as Fujian and Anhui, and brings historically extreme heavy rainfall to Huang-Huai region and North China. (2) After the genesis of Doksuri, as the circulations that affect the subtropical high are complicated, the numerical prediction of the intensity and location for the newborn tropical disturbance on the east of Doksuri has deviations, which is responsible for the track forecast errors. (3) The formation of double eyewall structure before Doksuri lands increases the difficulty of predicting the landfall intensity, while the favorable circulations and the application of multiple observations are supportive of the typhoon intensity prediction. (4) The sustainable water vapor transport from the southwest monsoon and Typhoon Khanun (2306), the terrain effect of Taihang Mountain, and the weak vertical wind shear along the typhoon track jointly help the tropical depression maintain for a long time after Doksuri makes landfall. |
