What causes storms?
Well, the earth is unevenly heated; we generally have warm air in the tropics and cold air over the polar regions. This creates a contrast in temperatures over the globe between the equator and the poles. Weather, in the form of low and high pressure systems, acts to rearrange these temperatures in an ongoing effort to balance out this temperature difference between the hot and cold regions on the earth, a re-distribution of heat.
So, during the each respective hemisphere’s winter, we have the largest contrast in temperatures between the poles and the equator. In turn this large temperature contrast cranks out the strongest storms. Conversely, in the summer, the pole to equator temperature gradient is comparatively weaker and thus we see less storm activity in the summer hemisphere.
