Why does temperature vary more in Northern Hemisphere & temperatures generally vary less in Southern Hemisphere than in northern hemisphere?
The combination of more direct rays of sunlight and more hours of daylight causes the hemisphere tilted toward the sun to receive more solar radiation and to have warmer temperatures. When the Northern Hemisphere is tilted toward the sun, latitudes between the equator and 90°N (the North Pole) are experiencing summer. Now, which of these hemispheres is most likely to have the greater annual temperature range? Yes, the Northern Hemisphere because it has more land area in summers will be warmer and winters cooler in the Northern Hemisphere when compared to those of the Southern Hemisphere.
Yes, the Northern Hemisphere because it has more land area. As summers will be warmer and winters cooler in the Northern Hemisphere when compared to those of the Southern Hemisphere. In Earth's present-day climate, the annually-averaged surface air temperature in the Northern Hemisphere (NH) is ? 1.5°C higher than in the Southern Hemisphere (SH). This interhemispheric temperature difference has been known for a long time, and scientists have pondered over its origin for centuries. The Southern hemisphere is more uniformly water than the Northern hemisphere. Large landmasses in the Northern hemisphere cause isotherms to bend toward the equator in winter and poles in summer as they change their temperature much more than the water. Most of the area of the southern hemisphere is ocean. The oceans warm up in the summer and retain heat during the winter. The northern hemisphere has much more land mass which loses its heat quickly. In the northern hemisphere, landmasses are cooler than the oceans. As the air is warmer over the oceans than over landmasses in the northern hemisphere, the isotherms bend towards the north (poles) when they cross the oceans and to the south (equator) over the continents. Frequently suggested causes include differences in seasonal insolation, the larger area of tropical land in the NH, albedo differences between the Earth's polar regions, and northward heat transport by the ocean circulation. The one exception to this pattern is the climate zones called the continental climates, which are not found at higher latitudes in the Southern Hemisphere. This is because the Southern Hemisphere land masses are not wide enough to produce a continental climate.
We find that the interhemispheric temperature difference is predominantly caused by meridional heat transport in the oceans, with an additional contribution from the albedo difference between Antarctica and the Arctic. The Southern Hemisphere has more water, which buffers temperature change. The Northern Hemisphere because it has more land area. As a result, summers will be warmer and winters cooler in the Northern Hemisphere when compared to those of the Southern Hemisphere.Most of the area of the southern hemisphere is ocean. The oceans warm up in the summer and retain heat during the winter. The northern hemisphere has much more land mass which loses its heat quickly. Generally, the Northern Hemisphere will experience different climate conditions than the Southern Hemisphere. For instance, one hemisphere will experience the cold conditions of winter while the other hemisphere experiences the warmer conditions of summer. The Southern Ocean has a large capacity to take up heat and store it in its waters, which leads to a smaller warming at the surface. The southern, water-dominated hemisphere thus reacts with a certain lag to global warming as compared to the northern, land-dominated hemisphere.
