Does wind power affect rainfall?

There are some studies on the impact of large-scale wind power plants on local climate, and the conclusions are somewhat confusing. Some increase rainfall, some reduce rainfall, some increase temperature, and some decrease temperature, so there is no conclusion yet.

This is related to the basis for comparison of current research methods. After all, there are too many factors that affect climate, and it is difficult to completely exclude other influences. Therefore, the comparison results are difficult to be reliable and will also be different from those in different places. The climate environment is related.

The main factors that affect rainfall are the water content of the clouds and temperature changes. If the water content is high enough, the clouds are thick enough and there are changes in temperature, rainfall will occur. The most basic principle of wind power generation is that a conductor cuts a magnetic field to generate current (that is, magnetism generates electricity), and the mechanical energy generated by the wind pushing the windmill is converted into electrical energy.

According to Baidu Wenku data, the wind field conditions for the construction of Caofeidian wind farm are as follows:

Meteorological conditions:

1. The quality of wind energy must be high . The primary condition for a wind farm site must be abundant wind energy resources. The annual average wind speed is above 5m/s, the effective wind hours at a height of 30m is above 6000h, and the effective wind energy density is above 240w/m^2. It is suitable for the construction of large wind farms.

2. The prevailing wind direction at the wind farm site is stable. Stable wind direction can not only increase wind energy utilization, but also extend the life of wind turbines.

3. The degree of turbulence in wind farms should be small.

4. There should be fewer natural disasters at wind power sites. Strong winds, hail, thunderstorms, earthquakes, etc. will all affect wind turbines.

Social and natural conditions: 1. The terrain of the wind power site should be relatively flat and the geological conditions should be good to facilitate civil construction.

2. Convenient transportation. It is necessary to consider whether the supply of equipment and the transportation of main construction materials of the proposed wind farm are convenient. Is it conducive to the construction and transportation of large cranes and flatbed trucks?

3. Wind farms should be as close as possible to the grid access point. For example: close to existing 10KV and 66KV substations and lines to reduce power loss and delivery project costs. Occupy as little cultivated land as possible to reduce ecological damage.

4. Surrounding environment. The construction of wind farms generally affects the normal life and migration of birds and birds. In order to protect the ecology, the site should try to avoid bird flight routes, migratory birds and animal habitats, etc., and stay away from nature reserves, military facilities, and densely populated areas.
