This winter season witnessed intense rainfall over the National Capital Region with the Indian Meteorological Department today saying the capital city received 261 per cent more rainfall than normal.
The IMD said three western disturbances affected northwest India in the current winter season up to February 20 and that more westerly system is likely to take effect from February 25 primarily over Western Himalayan region.
During the past three months, the rains were witnessed in Jammu and Kashmir, Himachal Pradesh and Uttarakhand with heavy falls at one or two places.
"Plains of northwest India including Delhi experienced fairly wide spread moderate rainfall. High impact weather phenomenon like hail storms was also reported," an IMD release said.
The active wet spells caused enhanced frequency of fog at IGI Airport and other airports of plains of northwest India during February.
The IMD also said Delhi received 261 per cent more rainfall, Gurgaon 270 per cent, Ghaziabad 192 per cent, Meerut 252 per cent, Gautam Budh Nagar 204 per cent, Bulandshahar 238 per cent, Baghpat 294 per cent, Panipat 222 per cent, Sonepat 248 per cent, Mewat 448 per cent and Palwal 412 per cent.
"During the current winter season, the WDs which moved across northwest India have been very active. On most occasions these westerly systems interacted with the moist air masses (from Arabian Sea and Bay of Bengal) which converged over Delhi and adjoining areas leading to enhanced rainfall activity," the IMD said.
Another important reason for active wet spells has been the prevalence of stronger than normal westerly winds in upper levels along Delhi latitude particularly during the current month, it said.
