Characteristics of Typhoon Du Julie;

From the morning of July 24th to the night, Typhoon Du experienced the process from typhoon level to super typhoon level. The reason for the strong intensity of Typhoon Du is that the sea surface temperature passed by the typhoon is relatively high, reaching 28℃ to 30℃, and the sea surface is relatively wide, which provides sufficient water vapor and energy for the typhoon; Secondly, the divergence between the north and south sides of the high-rise building in Du is relatively strong, which brings dynamic conditions for the further enhancement of the typhoon.

In addition, Typhoon Du Surui was formed in the east of the Philippines on 2 1. Compared with the typhoon in the South China Sea, this typhoon is far away from Chinese mainland and has enough time to develop and grow, which is one of the reasons for its strong intensity.
