It ranges from 450 mm in the e. to 100 mm in the n.-w. There are frequent failures of rain, leading to famine and large-scale migration of men and livestock. There is considerable seasonal and diurnal variation in temperature. The mean maximum temperatures in summer is 40°C but highest recorded temperatures reach up to 48 to 50°C. High temperatures and parched earth cause strong dust storms on several days during summer. In winter the mean minimum temperatures range between 3° and 8°C and lowest temperatures recorded are −4°C. Chilly winds blow during this season and frost occurs frequently. - [Previous: v1.c14.s2.3](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c14.s2.3) - [Next: v1.c14.s2.5](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c14.s2.5) - [Up: v1.c14.s2](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c14.s2) --- Source: [https://indike.org/pramana/ins.reference.ghosh-1989.v1.c14.s2.4](https://indike.org/pramana/ins.reference.ghosh-1989.v1.c14.s2.4) · Pramāṇa
