Why is summer in the southern hemisphere hotter than that in the northern hemisphere and winter colder than that in the northern hemisphere?

The statement of this question is completely wrong. In fact, the summer in the southern hemisphere is colder than that in the northern hemisphere, while the winter in the southern hemisphere is hotter than that in the northern hemisphere.

The reason for this problem may be that there are many and complicated factors affecting climate, including perihelion and apohelion of the earth, rotation and revolution of the earth, atmospheric circulation, topography, ocean currents and so on. At different time and place, these factors will interact in different ways, thus making the climate in different places show different characteristics.

The climate difference between the northern and southern hemispheres is mainly influenced by geographical location, seasons and ocean currents. The seasons in the southern hemisphere are opposite to those in the northern hemisphere. When it is summer in the northern hemisphere, it is winter. At this time, the northern hemisphere receives more solar radiation energy and the weather is hot, while the southern hemisphere receives less solar radiation energy and the weather is cold.

At the same time, the southern hemisphere has a vast ocean area, and its specific heat capacity is much larger than that of land, so seawater has a strong regulating effect on temperature. In summer, the specific heat capacity of seawater in the southern hemisphere is large, and the heating rate is slow, while the specific heat capacity of land is small, which makes the summer in the southern hemisphere cooler than that in the northern hemisphere. In winter, the sea water in the southern hemisphere has large specific heat capacity and slow cooling rate, while the land has small specific heat capacity and fast cooling rate, which makes the winter in the southern hemisphere warmer than that in the northern hemisphere.

In addition, Antarctica is one of the coldest regions in the world, and its extreme low temperature may be caused by its location in the polar region, lack of sunlight and wide coverage of ice and snow. The cold air from Antarctica spreads to the middle and high latitudes in the southern hemisphere with the wind direction and ocean currents, which makes the temperature in these areas lower. In contrast, the climate in the Arctic is relatively warm, and its extreme low temperature is mainly caused by the geographical location of the Arctic.

In a word, the climate characteristics of the northern and southern hemispheres are influenced by many factors, which interact and influence each other. On the basis of understanding these factors, we can better understand the climate differences and characteristics between the northern and southern hemispheres.
