Different Impacts of Summer in the Northern and Southern Hemispheres on Climate Change | CBCGDF Climate Change Working Group
Summer in the Northern and Southern Hemispheres has distinct influences on climate change.
In the Northern Hemisphere summer, the large landmasses play a significant role. The extensive heating of the continents can lead to the formation of strong heat domes. For example, in North America and Asia, these heat domes can cause extreme heatwaves. The warm air masses can also affect the jet stream, causing it to become more wavy and leading to abnormal weather patterns such as droughts in some regions and heavy rainfall in others.
Conversely, in the Southern Hemisphere summer, the relatively larger ocean areas have a moderating effect. However, the Antarctic ozone hole can influence the climate during this time. The ozone depletion allows more ultraviolet radiation to reach the surface, which can heat the upper layers of the ocean and affect the local climate system. Also, the strong ocean currents in the Southern Hemisphere, like the Antarctic Circumpolar Current, can be affected by the summer conditions, which in turn can influence the global climate through heat transfer and the distribution of nutrients. In conclusion, the different geographical features in the two hemispheres during summer contribute to their diverse impacts on climate change.
