If morning air is cool and humid but afternoon air feels warm and dry, what may be the main reason?

Answer and explanation

Correct answer: Temperature rise lowers relative humidity

Correct answer: A. Relative humidity is not simply the amount of water vapour; it compares the actual vapour present with the maximum vapour the air could hold at that temperature. As temperature rises during the day, the saturation capacity of air increases. If the actual amount of vapour does not increase at the same rate, the relative humidity percentage falls, so the air may feel drier. B is wrong because warming does not necessarily remove all water vapour; the amount may remain or change only partly. C is obviously wrong because the atmosphere remains present. D is wrong because condensation nuclei do not normally disappear at noon; their presence is not the main explanation for ordinary daytime dryness. The phrase “feels warm and dry” usually points to increased temperature and reduced relative humidity, not zero moisture. Memory cue: warmer air has more capacity, so the same vapour gives a lower relative percentage.
