Does India also experiences Tornadoes ?
When I was a child I used to watch a show 'storm-chasers' which used to be telecasted on Discovery channel and watching that I used to get excited that I will also do the same whenever I will be getting a chance to do that around my place but sadly from that age until now I never saw any tornado nor heard of any tornado hitting India.
2 days back a news started circulating everywhere that a tornado wrecked havoc in USA after ripping through 6 states of America with Kentucky facing most of the brunt with having wind speeds gusting upto 320kmph and killing atleast 100. With this sad news many had a curiosity that "whether India also experiences tornadoes or not ?"
Does it occur in India ?
It does happen in India but on a relatively lower and lesser intense scale than in US
For instance major recorded tornadoes are as follows:
- Calcutta--1838--215 fatalities
- Assam-- 1963 --- 139 fatalities
- New Dehli -- 1978 -- 700 fatalities
- Odisha -- 1978 -- 150 fatalities
- West Bengal -- 1993 -- 145 fatalities
- West Bengal and Odisha -- 1998 -- 120 fatalities (2000 injuries)
- Odisha -- 2009 -- 20 fatalities -- 150 injured -- 300 homes, 11 villages destroyed.
- Ranchi, Jharkhand -- 2013 --
reference :list of tornadoes in Asia
but for tornadoes to occur all climatic conditions needs to happen simultaneously
A tornado forms when
1. Humid air is trapped beneath cold, dry air.
2. A “cap” between the two air bodies is disturbed by wind or a weather front.
3. Lower air rises and expands toward the reduced pressure aloft, punching a hole in the cap.
4. Moisture condenses, releasing latent heat which warms the air, causing it to rise by convection at up to 150 mph. The cloud has now formed a thunderstorm.
5. The thunderstorm may die out in intense rain and/or hail, or it may spawn a tornado.
6. Interactions between air at various altitudes, humidities and temperatures cause rain, lightning, air circulation and a strong, rotating updraft, now called a “mesocyclone.” This rotation is almost always counter-clockwise (seen from above) in the Northern Hemisphere.
7. A tornado may form below the mesocyclone. As the spinning air column narrows, it rotates faster and the fcloud extends higher into the storm.

So if the conditions do fall into place then it will give rise to a tornado which gets unlikely in a vast country like India. Only a certain area and a certain time period gives rise to these conditions therby making tornadoes a rare occurence in India.
So next time you see someone making claims something relating about tornadoes and India...make their facts straight :)
