Dew is not formed on a strong windy night because

Dew is not formed on a strong windy night primarily because the rate of evaporation is fast. Wind increases the movement of air, which in turn enhances the rate of evaporation by carrying away the thin layer of moisture near the ground. As a result, any moisture that condenses on surfaces at night due to cooling temperatures is quickly evaporated by the wind, preventing the formation of dew. This phenomenon is particularly noticeable on windy nights when the air movement is strong enough to disrupt the delicate balance between condensation and evaporation needed for dew formation. Additionally, wind can also mix and disperse the air, reducing the relative humidity near the ground, which further inhibits dew formation. Therefore, the correct answer is [A] the rate of evaporation is fast. Understanding this effect of wind on dew formation is essential in meteorology and agriculture, particularly for predicting overnight condensation and its impact on crops and outdoor activities.
