(KXAN) — The ongoing research into Mother Nature’s storms has yielded interesting results thanks to research done by scientists. A recent study from the University of Chicago gave us another one. The southern hemisphere is more stormy than the northern one.
The Southern Hemisphere covers most of South America, about a third of Africa, as well as Antarctica and some Asian islands.
Research done in this area has shown that the circulation of the oceans, combined with the large mountainous areas of the Northern Hemisphere, helps make the Southern Hemisphere more stormy. And yes, this increase could also be due to climate change projections.
The oceans carry energy from the depths of the bottom to the surface. Since water sinks in the Arctic and rises near Antarctica, there is a difference in energy between north and south. In the southern hemisphere, the mass of the ocean is greater than in the northern. There was a slight increase in the average wave height. Satellite observations and more than 80 ocean boys show a clear 8% increase in wind speed in the southern oceans. This number is noticeably smaller in the equatorial Atlantic and the Pacific along with the North Atlantic. The data were collected over more than 30 years.
Another element that comes into play is the mountain, or better yet, the topography. The study found that the larger the mountain range, the more disrupted the airflow, which reduces the impact of storms. Thus, the more mountain ranges in the Northern Hemisphere, the fewer storms.
What was interesting about this study was that the scientists were able to raze every mountain to the ground. This resulted in a 50% reduction in the difference between the two hemispheres. This is one of the most interesting aspects of this study.
Finally, the study concluded that models predicting climate change have shown that storms are intensifying in the Southern Hemisphere, while only marginal changes are observed in the Northern Hemisphere.
