History

Under the Köppen climate classification the greater part of Rajasthan falls under Hot Desert (BWh) and remaining portions of the state falls under Hot Semi Arid (BSh); the climate of the state ranges from arid to semi-arid. Rajasthan receives low and variable rainfalls and thereby is prone to droughts. As Rajasthan is the dry and hot state, Unbelievable hailstorm covered Nagaur, Rajasthan in a thin snow-like icy blanket in December 2019. Later on, it is clarified that this is not a snowfall but a hailstorm, endorse by western disturbances. The climate has changed in winters like never before. [1]
