What is the biggest tornado in the world?

The biggest tornado in the world is 1925, the strongest tornado in America.

On March 1925 and 18, a strong tornado appeared in the United States, moving at a speed of 96.6 kilometers per hour, passing through the "three-state tornado" in southeastern Missouri, southern Illinois and northern Indiana, with a journey of 354 kilometers, causing a large number of property losses, causing 689 deaths and as many as 1980 injuries. This is the biggest tornado ever in the world.

Tornadoes are recorded on all continents except Antarctica. Tornadoes mainly occur in mid-latitude areas, among which the United States is the most frequent, known as the "tornado kingdom" and known as the "hometown of tornadoes", and its tornadoes account for about 75% of the total number of tornadoes in the world. Florida and south-central plains in the United States are high-incidence areas of tornadoes, and the south-central plains are called "tornado corridors".

Tornadoes often bring incalculable losses to human beings. Modern science knows very little about tornadoes. The aerodynamics they used to explain the causes of tornadoes-the turbulence of air forms rotation, and the mutual stretching of cold and warm airflow makes the rotating air column a tornado-can't explain the abnormal phenomena in tornadoes at all.
