Its direct effects are physical or mechanical while indirect effects are physiological .
Wind modifies the humidity .
Dry winds diffuse dwarfing of plants .
Wind helps in pollination , dispersal of fruits and seeds and prevents frost damage .
Sometimes shrubs and trees are planted to protect the field against wind .
Such structures are known as wind breaks or shelter belt .
These plants are planted at 90degree to the wind velocity.
It affects both plants and animals in the following ways
1- Strong winds cause soil erosion so reducing soil fertility .
These also cause desertification by shifting of sand particles to fertile areas .
2- These cause lodging of plants like wheat , rice , maize , oat , sugarcane , etc .
3- These increase the rates of evaporation and transpiration leading to desiccation which cause dwarfism in the plants .
