This is why the Southern Hemisphere has more storms than the Northern Hemisphere

There are several reasons why there are more storms in the southern hemisphere than in the northern hemisphere. One of the main reasons is that most of the Earth is covered with water and the distribution of this water varies between the two hemispheres. In the Southern Hemisphere, there is much more water than in the Northern Hemisphere, which can create more conditions for the development of storms.

Look at the main factors that make the difference between the South and the North:

Researcher Tiffany Shaw, with the University of Chicago, has highlighted two main factors for the occurrence of these storms, namely:

The Coriolis effect is greater in the Southern Hemisphere than in the Northern Hemisphere, due to the greater distance from the axis Earth’s rotation. The Coriolis effect is the force created by the Earth’s rotation, which deflects winds to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

This wind deflection leads to a greater convergence of warm, moist air in the Southern Hemisphere, which can lead to increased storm formation.

The Hadley circulation is a wind pattern that occurs between the equator and subtropical latitudes in both hemispheres. In the Southern Hemisphere, the Hadley circulation is more intense than in the Northern Hemisphere, which means that there is more warm, moist air being transported from the tropics to higher latitudes.

Moving warm, moist air could create more storms in the Southern Hemisphere.

Another factor that can contribute to more storms is terrain. The mountains and elevations in the Southern Hemisphere are different from those in the Northern Hemisphere, and this can affect air circulation and create favorable conditions for storms.

Moreover, the position of South America and Australiawhich are located in the southern hemisphere, can contribute to the formation of thunderstorms on these continents.
