360:... The onset of a western disturbance is heralded by dense thunder clouds accompanied by heavy rain or snow. The weather conditions during winter are generally influenced by the distribution pattern of pressure in Central and West Asia. In winter, due to the shifting of the pressure belts, the westerlies blow from 20°N to 50°N latitude and Northern India comes under the influence of the winds and cyclones rising from the Mediterranean Sea. In the wake of the disturbance comes cold air and often accompanied by strong winds ...

winter season has great importance in agriculture, particularly for the rabi crops. Wheat among them is one of the most important crops, which helps to meet India's food security. An average of four to five western disturbances form during the winter season. The rainfall distribution and amount varies with every western disturbance.
544:... These states are: Punjab, Haryana, Himachal Pradesh, Jammu & Kashmir, Uttarakhand and Uttar Pradesh. These states receive some rainfall (precipitation) during the rabi season, brought about by western disturbances, which originate in the Mediterranean region. These showers are very beneficial for rabi crops ...
