Why is transpiration affected by light, air relative humidity and wind?

The stomatal opening is regulated by light, and then the light will increase the temperature of the leaf surface, and the water in the stomata will spread into the air more quickly. Transpiration will reduce the leaf temperature. When the temperature is too high, the stomata will automatically close and the transpiration rate will slow down.

Air humidity and wind affect the diffusion speed of water into the air in pores. The greater the humidity, the slower the water diffusion rate and the lower the transpiration rate, and vice versa. The influence of the wind is the same.
