Is there often a typhoon in the northeast?

Because the northeast latitude is relatively high, even if the frequency of typhoon patronage is still small, it is still possible to be patronized by typhoons, because some typhoons are strong enough to blow to high latitudes.

However, the typhoon brothers still prefer the southern regions, especially Guangdong, Fujian and Zhejiang, which are favored by the typhoon brothers several times every year. Moreover, the arrival of typhoons in Guangdong, Fujian and Zhejiang causes many crops to be damaged every year, which makes many farmers miserable.

Because once the typhoon comes, many crops are not very strong in wind resistance, so they are easily destroyed by strong winds.

Extended data:

The formation of typhoon requires the following conditions: the sea surface water temperature is above 26.5℃; Initial disturbance of a positive vorticity; The shear of ambient wind in the vertical direction is very small; Low pressure or cloud disturbance is at least several latitudes from the equator.

Because people don't fully understand the formation of typhoons now, the above list is only a necessary condition for the formation of typhoons. The initial stage of typhoon is tropical depression, and it usually takes about 2 days from the initial low-pressure circulation to the maximum average wind force near the center, only three or four days for the slow one and only a few hours for the fast one.

In the development stage, the typhoon continuously absorbs energy until the central air pressure reaches the lowest value and the wind speed reaches the maximum value. After the typhoon landed, under the joint influence of ground friction and insufficient energy supply, it will quickly weaken the death.
