Detailed explanation-1: -Increased movement of the air around a plant will result in a higher transpiration rate. If there is no wind, the air around the leaf is still and transpiration raises the humidity around each leaf. Wind moves saturated air, close to the leaf, away replacing it with less saturated air.

Detailed explanation-2: -Air movement such as wind can aid with transpiration. When the air is still or there is no wind, humidity may buildup around the plant from transpiration eventually decreasing the amount of water being released. When there is wind present, this causes the air to be replaced constantly allowing the plant to transpire.

Detailed explanation-3: -Light intensity: The transpiration rate is increased due to the increase in light intensity. During daytime in the sunlight, the rate of transpiration is faster. This is because the stomata remains open to allow the inward diffusion of carbon dioxide for photosynthesis.

Detailed explanation-4: -Temperature: A rise in temperature increases the water loss by transpiration. Transpiration increases with an increase in temperature to a certain point. Stomata close when the temperature falls to very low or increases to very high ultimately ceasing the process of transpiration.
