The Western disturbance and its induced cyclonic circulation over Rajasthan and adjoining areas have moved away, leading to clear weather conditions. Whenever a Western Disturbance approaches the Western Himalayas and induces a cyclonic circulation over Northern Plains, wind direction tends to change from north westerly to easterly, leading to increase in minimums.
Similar was the case recently, wherein the minimum temperature of Delhi increased by almost 7 degrees Celsius in just about 48 hours from a mere 6 degrees on February 7 to a double digit of 12.8 degrees on February 9.
However, now, minimums in Delhi, Punjab, Haryana and Rajasthan have dropped once again by 3-5 degrees after the passage of Western Disturbance and weakening of the induced Cyclonic Circulation. In case of Delhi, the fall in temperatures was around 4 degrees in 24 hours, from 12.8 degrees yesterday to 9.1 degrees Celsius today morning.
In fact, minimums of many districts of Rajasthan and Haryana have once again come down in single digit. Now, the weather is expected to remain clear and day temperatures are expected to increase leading to relief from cold conditions during the day time. However, mornings and nights will continue to remain cold.
