With reference to tornado, consider the following statements:1. It is ...

Recently, a deadly tornado struck the Mainaguri area of Jalpaiguri district of West Bengal for 10 minutes and killed five people and injured over a 100.

It is a land-based vertical column of violently rotating air that forms from a thunderstorm to the ground. It can have wind speeds in the range of 105-322 kilometres per hour.
The rotating column is physically connected to the cloud base or wall cloud and is often visible as a cloud-filled "condensation funnel". If the air is dry enough, the tornado may only appear as a swirl of dirt on the ground without a visible connection to the cloud above.
The tornado over the sea is called water spouts.
Formation: Any collision of warm, moist air with dry, cool air in the presence of a low pressure system like a trough causes thunderstorms and tornadoes.
Geographical distribution:
It occurs most commonly on continents in the mid-latitudes (between 20 and 60 degrees north and south), where they are frequently associated with thunderstorms that develop in regions where cold polar air meets warm tropical air.
Tornadoes are the most common in the United States, Argentina and Bangladesh.
The Enhanced Fujita scale is used to measure tornado strength. It is used to assign tornado a 'rating' based on estimated wind speeds and related damage.

Hence only statements 1 and 3 are correct.
