Delhi-NCR has been witnessing wide variations in the temperatures ever since the beginning of February, particularly the minimum temperatures.
Till February 3, national capital has been witnessing near normal temperatures around 9°C. Thereafter, the mercury increased significantly between February 4-6 and settled 5-6 degrees above the normal average temperature.
This sudden and recurring variation in the temperatures is governed by change in wind direction. An active Western Disturbance had started affecting Jammu and Kashmir around February 4, due to which cold northerly winds were replaced by relatively warm and humid southwesterly winds.
These winds were instrumental in rising the temperatures. But as soon as Western Disturbance moved away eastwards, the normal flow of cold winds from north once commenced again. Thus, the night temperatures which were earlier settling several notches above the average mean once again started to drop.
On February 7, Delhi recorded minimum temperature of 8.6°C, which was in fact one degree below normal.
Now, both the day and night temperatures are likely to be near normal, predicts Skymet Weather. According to weathermen, a fresh Western Disturbance is approaching Western Himalayas and will start affecting Jammu and Kashmir by the evening or night hours of Tuesday.
With this, we can once again expect a marginal rise in minimum temperatures during the next 24 hours. But since the Western Disturbance is moving at a fast pace, night temperatures will drop by 1-2 degrees once more on February 9 and February 10.
