The storms, which are considered an annual weather pattern in the region, surprised authorities this time, given the destruction caused.
Rajasthan and Uttar Pradesh were battered by dust storms which claimed more than 100 lives, damaging crops and destroying structures in several parts of the two states.
The storms, which are considered an annual weather pattern in the region, surprised authorities this time, given the destruction caused. But the bad news isn't over. The Meteorological Department has predicted that the storms would reoccur in the next 72 hours.
Here's why the storms were so deadly this year around.
What made the annual dust storm so deadly?
The dust storm is not this intense and it does not cover such a large area. However, unusually warm weather prevailing in the region, availability of moisture and an unstable atmosphere turned the storm causing a trail of destruction, meteorologists told Hindustan Times.
Mentioning the cause of the disastrous storm that swept the western state of Rajasthan and northern state of UP, officials explained that storms need moisture, warm temperatures, and an agitated atmosphere to push warm moist air upwards, where storm clouds are formed.
This is what happened in Rajasthan and UP. A cyclonic circulation over formed over Haryana and the high temperatures prevailing in adjoining areas meant that air close to land was pushed upwards where storm clouds were formed.
The moisture provided by winds blowing from the Bay of Bengal, created a system of low pressure leading to the massive thunderstorms.
Met says more to comeThe Met department has issued a warning that more such storms would occur in the next three days. In a statement, it said that besides the two states, West Bengal, Uttarakhand, Punjab, Haryana, Jammu and Kashmir, Assam, Meghalaya, Nagaland, Mizoram, Tripura, Manipur, Odisha and Kerala are expected to experience thunderstorms and heavy showers.
