Question

Humidity is the amount of moisture present in the air and relative humidity is the ratio between the amount of water vapour present in the air and the maximum capacity of the air to hold the water
Then explain the following statement :
"Humidity determines the amount of precipitation and relative humidity tells us about its possibility. How ?"

Answer 1

Relative humidity tells us about the precipitation because more moisture that air holds gives rise to more precipitation as The relative humidity determines the amount and rate of evaporation. If moisture is added by evaporation, the relative humidity will increase which increase the humidity and hence precipitation.
