Why has the weather changed from India to Pakistan and Afghanistan? What is this 1,000-km-long rain band? Scientists are also puzzled.

News Topical, Digital Desk : Rain and hailstorms have been lashing North India, including Delhi-NCR, for the past two days. Unseasonal rain, thunderstorms, and hailstorms are being experienced not only in India but also in Pakistan and Afghanistan.

The rain has caused the mercury to drop to 7 degrees, and a chill is once again evident. Unseasonal rain, especially in March, at the start of summer, is not a common occurrence; it is a significant indicator of changing climate patterns. Scientists are also puzzled by the unseasonal rain.

Why has the weather pattern changed?

An unusual weather phenomenon is occurring across parts of India, Pakistan, and Afghanistan due to an active western disturbance. According to the Meteorological Department, this is an upper-air cyclonic circulation currently active over northern Pakistan.

1000 km long rain band

Additionally, a low-pressure western disturbance, formed in a straight line, is creating a 1,000-kilometer-long rain band from Afghanistan through Pakistan to India. Western disturbances typically occur during the winter months of December and February, originating in the Mediterranean Sea and moving northeastward, bringing snowfall and cold waves.

But this time, this disturbance became active in March, causing not only rain but also strong winds, hailstorms, and light to moderate snowfall in some areas. This is the reason why temperatures are dropping.

A Western Disturbance is expected to bring thunderstorms, hailstorms, and strong winds to northwest India. Heavy to very heavy rainfall is expected over Sub-Himalayan West Bengal and Sikkim, and intense rainfall over South Karnataka, Andhra Pradesh, Kerala, and Tamil Nadu.

What is the source of moisture?

Now the question is where is this unusual western disturbance getting its moisture? Let us tell you that this system is receiving its moisture from the oceans. The source of moisture required for this unusual western disturbance is evaporation over the Mediterranean Sea, the Caspian Sea, the Black Sea, and the Persian Gulf.
