Humidity in Rajasthan

Humidity in Rajasthan – Introduction
  • Humidity – Humidity is the amount of water vapor present in the air. Water vapor is the gaseous state of water and is invisible to the human eye. Humidity indicates the likelihood of precipitation, dew, or fog. The amount of water vapor that is needed to achieve saturation increases as the temperature increases.
  • Relative Humidity – Relative Humidity is percentage of the water vapor present in the air to the maximum water vapor which can be hold by air. If relative humidity is less, means there is less amount of water vapor present in the air. Hence, there is very less possibility of rain in that area. If relative humidity is high, means there is high amount of water vapor present in the air. Hence, there is very high possibility of rain in that area.
  • Average Humidity – The average humidity is the average of relative humidity over the years. This gives a clear picture of the climate, rainfall and the relative humidity.
Humidity in Rajasthan – Relative humidity in Rajasthan
  • In the months of summer season, March to June, the relative humidity is generally very low in the State of Rajasthan. The relative humidity in the summer seasons remains about 30-40% all over the Rajasthan. Due to this low humidity, there is no rainfall in the summer season.
  • However, in the months of rainy season, July to September, the relative humidity is rises to 70% in the west Rajasthan and 75% in the East Rajasthan. Due to this high relative humidity, there is high amount of rainfall in this time.
  • There is high variation in the relative humidity of a day in a particular region in Rajasthan except the monsoon season.
  • The variation in the relative humidity is low during the monsoon in the East Rajasthan. However, in the western Rajasthan, the variation is much higher. The relative humidity drops to 22-27% in the afternoon due to high temperature. This makes this region a dry and arid region.
  • The relative humidity in the arid region of western Rajasthan is also very high. However, due to unfavorable circulation of the atmosphere, low precipitation occurs in this region as compared to semi-arid and sub-humid regions of the Rajasthan.
Humidity in Rajasthan – Average humidity in Rajasthan
  • The annual average of relative humidity of Rajasthan was 61% in 1980. Now, the annual average of relative humidity of Rajasthan was 49% in 2010. There is a gradual decline in the annual average of relative humidity of Rajasthan over the last 30 years.
  • The main reason in this decline is the deforestation and other activities.
