Which of the following statements about tornadoes are correct?Tornadoe...
Statement:
1. Tornadoes usually spin anticlockwise in the northern hemisphere.
2. Tornadoes usually spin clockwise in the southern hemisphere.
Explanation:
Tornadoes are violent and destructive rotating columns of air that are associated with severe thunderstorms. They are often characterized by a visible condensation funnel and can cause significant damage and loss of life. The direction of rotation of tornadoes is influenced by the Coriolis effect, which is caused by the rotation of the Earth.
Tornadoes in the Northern Hemisphere:
In the northern hemisphere, tornadoes usually spin anticlockwise. This is because of the Coriolis effect, which causes moving air to be deflected to the right in the northern hemisphere. As a result, air in a spinning thunderstorm updraft is also deflected to the right, causing the tornado to rotate counterclockwise when viewed from above. Therefore, statement 1 is correct.
Tornadoes in the Southern Hemisphere:
In the southern hemisphere, tornadoes usually spin clockwise. This is again due to the Coriolis effect, but in this case, moving air is deflected to the left. As a result, the spinning updraft in a thunderstorm in the southern hemisphere is deflected to the left, causing the tornado to rotate clockwise when viewed from above. Therefore, statement 2 is correct.
Conclusion:
Based on the explanation above, both statements 1 and 2 are correct. Tornadoes usually spin anticlockwise in the northern hemisphere and clockwise in the southern hemisphere. Therefore, the correct answer is option 'B' - 2 and 3.
