It rains again in Xiamen. Why is there such extreme weather?

Recently, it began to hail again in Xiamen. So why is this extreme weather, and how is the hail formed? In fact, hail is caused by the evaporation of water on the surface of the earth and rising into the air, forming clouds, and then freezing into pieces when it meets cold air or when the air is extremely cold, forming hail. So, we can see the hail in the sky.

1. In case of hail, close the doors and windows and try not to go out. Because hail is granular or massive, it is easy to hurt pedestrians when it falls from the sky. Moreover, even if you travel, you should choose an umbrella with good quality, because an umbrella with poor quality or a thin umbrella will cause hail to break through the umbrella and hit your head.

Hail is not only a bad weather. Sandstorm is also an extreme weather. Under normal circumstances, sandstorms mainly appear in cities in the north, especially in cities near Inner Mongolia. Sandstorm is mainly due to the dry earth, and then it encounters windy weather, which causes the sand and gravel on the surface to be blown into the sky, thus forming the sandstorm weather we finally see. Then, when the sandstorm comes, it is necessary to reduce travel and close the doors and windows. If you travel, you should wear a mask and a protective mask. Because if you don't wear a mask, the sand in the air will be inhaled into our lungs, which will affect the health of the lungs and more often cause cough and dyspnea. Close the doors and windows when you are at home to prevent sand from drifting into the room and causing secondary pollution.

Whether it is hail weather or other bad weather, it indirectly reminds us to protect the environment and care for our homeland. Try to walk out at ordinary times to reduce air pollution. You can also plant some green trees, because green plants can effectively absorb carbon dioxide, release oxygen and purify our air.
