Principle objective of this lecture is to present on What is Relative Humidity. Relative Humidity is the amount of water vapour present in air expressed as a percentage of the amount needed for saturation at the same temperature. Here also briefly describe on what is the uneven heating and cooling of the land and sea and four main parts of the water cycle. The relative humidity is the percent of saturation humidity, generally calculated in relation to saturated vapor density.
