1. Formation environment: Tornadoes are mainly formed on land, which is the result of the interaction between strong convective airflow and unstable atmospheric conditions, while eddies are mainly formed in water, which is due to the influence of unstable water flow or topography.
2. Damage range: The damage range of tornado is wider than that of whirlpool. Tornado winds can reach hundreds of kilometers per hour, which is extremely destructive. It is easy to destroy buildings and uproot trees, causing power outages and traffic paralysis. Although the vortex has a fast velocity and a large gravity, its influence range is small, mainly affecting the water body and its surroundings.
3. Tornado is a strong small-scale air vortex, which occurs in thunderstorm weather. It is formed because the warm and humid air in the atmosphere meets the cold and dry air to form a rotating airflow, which gradually extends downward to the ground. Tornadoes are extremely destructive because of their high wind speed, which can reach hundreds of kilometers per hour.
