Although typhoon is a kind of disastrous weather which
causes great losses and damage to people's production
and life, it also has its contribution.
The peak period of typhoon occurred in July and September,
when it is hot and dry in the southeast coast and the middle
and lower areas of the Yangtze river. Typhoon brings abundant
rain to crops that need a lot of water, which is very
beneficial to agricultural production.
Although there is no heavy rain in areas that are far away
from the sea and less affected by the typhoon, there will
also be cloudy days or light rain, which can alleviate the
drought situation. So, farmers in these areas also call the
precipitation brought by the typhoon “timely rain”.
Typhoon is not only doing harm to people , but also protecting
them. It brings fresh water to mankind, greatly alleviating the
global water shortage. A typhoon of modest diameter can bring
a high rainfall of 3 billion tons when it lands.
In addition, typhoons have kept the cold and heat of the world
relatively balanced. The equatorial region has a hot climate,
and if it weren't for typhoons to dissipate the heat, the tropics
would be hotter, the cold areas would be colder, and temperate
zones would disappear from the earth. In a word, when there are
too many typhoons or they are big, it is not good; however, at
the same time, the earth can’t function well without them.
