Common weather signs include: light rain, moderate rain, heavy rain, sunny, cloudy, overcast, heavy rain, etc.

The functions of weather signs:

1. The impact of weather on industrial production is very extensive. Whether it is the selection of the factory site, the design of the building, or all aspects of raw material storage, manufacturing, product storage and transportation, they are all affected by meteorological conditions such as temperature, humidity, precipitation, wind, and insolation. Especially disastrous weather, such as tropical storms and typhoons, heavy rains and floods, power transmission line interruptions or damage to factories and equipment, flooded warehouses, and worker casualties and inability to go to work; droughts cause insufficient water supply.

2. Fires caused by lightning, etc.; freezing and cracking of water pipes and oil pipelines and other freezing damage caused by low temperature; high temperature and low humidity can easily induce fires and explosions; high temperature and high humidity can easily cause corrosion and mildew of raw materials, etc., as well as affect the health of workers. Physical health and production efficiency, etc., all directly or indirectly affect industrial production.
