Landing time of Typhoon Jerahua

In 2023, Typhoon "Jerahua" made landfall in the southern part of the South China Sea on June 5438+February 19.

The tropical disturbance in the eastern Philippines intensified at 8: 00 on February 6, and 5438+07 was this year's typhoon "Jielahua" (tropical storm level). 18 at 8: 00 am on June 8, its center was located at 7.7 degrees north latitude and 126.6 degrees east longitude, about 980 kilometers southeast of Manila, Philippines.

Seven-level wind circle radius 100- 120km. It is estimated that "Jielahua" will move rapidly to the north-north direction at a speed of 35-40 kilometers per hour, and will land on the southeast coast of the Philippines. After landing, it will gradually weaken and enter the southern South China Sea from the afternoon of 19 to the night.

Impact:

After typhoon 17 enters the South China Sea, it is most likely a tropical disturbance or a tropical depression, which should not be very helpful for cold air to go south to Guangdong. But unexpectedly, this tropical disturbance developed so rapidly that it even skipped the level of tropical depression and directly numbered it as typhoon level.

Therefore, the rapid generation of this typhoon will also make the cold air in Guangdong more active. Originally, the first wave of strong cold air hit, the temperature in Guangdong was low, and a typhoon helped the second wave of strong cold air to go south, which was a biting cold wind.

Therefore, the Guangdong Meteorological Observatory predicts that around 65438+February 2 1 in 2023, the minimum temperature in Guangzhou, the capital city of Guangdong, will drop to about 4℃, and the minimum temperature in the alpine mountain area in northern Guangdong will drop to-2℃ ~ 0℃, and freezing weather will occur.

Also, after typhoon 17 enters the South China Sea, the intensity of typhoon will determine the intensity of cold air. If the intensity is greater, the cold air will go south more violently, and the cooling rate in Guangdong will be even greater, even if it breaks 3 C.

So next, we will see whether 17 typhoon "Jielahua" can develop again in the South China Sea after crossing the ridge line of the cold north wind. How strong the typhoon is can determine how low the temperature is in Guangdong.
