For the last 48 hours, both maximum and minimum temperatures are showing a decreasing trend over entire Northwest and Central India.
Earlier the minimum temperatures were in double digits all over Punjab, Haryana, Delhi and North Rajasthan. They have now decreased by 5 to 10 degrees in a span of 48 hours. At present, almost all the places are recording single digit minimums.
However, this trend is not likely to sustain for long. By February 6, a fresh Western Disturbance will start affecting weather in terms of temperatures, clouding and precipitation. During that time, temperatures will once again rise by 4 to 6 degree Celsius.
This means that the winter chill will vanish very soon. Warm weather which was experienced by North Indians throughout the winter is not good for Rabi crops, particularly wheat and mustard. These crops require lower minimums, below 5 degree Celsius, for a prolonged period. This has not been the case this time. Higher temperatures will lead to a decrease in the crop quality. Crops will mature early, leading to lesser yield and inferior quality of seeds.
Moreover, this warmth will continue throughout the month of February and most of March. Temperatures will remain above normal till March. Due to high temperatures, unseasonal rains are also possible during March. The harvesting season begins late March into early April and unseasonal rains will hamper the standing crops, decreasing production.
