Weather in Gongshu District of Hangzhou 15 days.

Strong convective weather such as hail in Hangzhou will have a very bad impact on the local ecological environment. The weather in Hangzhou is very warm now, and flowers, trees and crops are in an important growth stage. Such strong convective weather will cause great losses to agricultural production. It will also cause the local temperature to drop sharply, which will affect people's health and normal travel. It will also adversely affect the migration of local birds and migratory birds and cause changes in the biological chain.

Effect of gale and hail on crops The weather in Hangzhou is sunny and the temperature is suitable this season. However, a series of hailstorms made the local people feel the changes of the four seasons in one day, which also made people feel scared and strange. The bad weather in Hangzhou this time is rare, and the impact of such strong convective weather on the local ecological environment is not optimistic. In the basic seasonal stages such as spring ploughing, primary crops will cause great losses, and the wind and hail will blow the crops to pieces, which will greatly affect the normal growth of crops, and the loss is also heartbreaking. The influence of crops will directly bring trouble to people's daily life. Fruit trees and vegetables will also be affected. This season is the time when fruit trees bloom, and windy weather will blow away the flowers, which will affect the subsequent fruiting rate. The same vegetables will also be damaged by hail, which will affect the harvest and people's daily consumption.

The sudden arrival of temperature changes, strong winds and hail weather also directly affects the normal travel of people living in Hangzhou. However, after sunny days are affected by strong winds and hail, the local temperature will change greatly, and the rapid cooling will also affect people's health to varying degrees. It was very hot at noon, so I asked someone to turn on the air conditioner to cool down. The storm and hail in the afternoon caught people off guard, and they found thick clothes in winter to keep out the cold. It has brought great troubles to people's lives, especially children and the elderly, who need to pay special attention to their physical condition. The impact of such strong convective weather on the local ecological environment also requires people who often go out to pay more attention to safety.

The influence of birds The normal environment in Hangzhou is already blooming in spring, but the sudden strong wind and hail have also caused many local birds to freeze to death, and the same migratory birds will be badly affected when they migrate or return to the local area. However, the role of birds in the ecological environment can not be ignored. At the same time, the impact of local strong convective weather will cause many pests and diseases, affecting the ecological balance for a period of time. The increase of pests will cause the slow survival and diseases of plants, affect the local ecological environment and bring inconvenience to people's lives.
