When will the weather get hot?

Geographically, because the earth revolves around the sun for one year, the direct position of the sun divides the earth into four seasons. The Tropic of Cancer is a round-trip restriction for direct sunlight. Around March 23 every year, the sun shines directly at the equator. At this time, it is the vernal equinox. On June 22nd, the so-called summer solstice sun shone directly on the Tropic of Cancer, which was the farthest place where the sun shone in the northern hemisphere. As for the polar day in the Arctic and the polar night in the Antarctic, it is 24 hours, day and night. Let's get down to business. In June, due to sunlight, the northern hemisphere began to get hot. It is reasonable that June should be the hottest time, so why is July and August the hottest? This is because the temperature of the earth is in July and August, and the heat of the earth itself begins to radiate. This is the hottest time, so summer is the hottest time. This time is the coldest time in the southern hemisphere. Because the sun does not shine directly there, the so-called autumnal equinox is around September 23, that is, the sun begins to move from north to south, and the sun shines on the equator again, and the temperature in the hemisphere is cold. February 22, 2008 is the winter solstice. The sun shines directly on the Tropic of Capricorn, and the southern hemisphere begins to get hot and the hemisphere begins to get cold. The reason is basically the same as above. March 23rd is another year, and this is the second year.

The sun moves from the southern hemisphere to the northern hemisphere. The southern hemisphere began to get cold and the northern hemisphere began to get hot. Because we are in the northern hemisphere, winter is the coldest time and summer is the hottest time. If we are in the southern hemisphere, it is coldest in summer and hottest in winter. There is another special case. If you live on the polar line, it will be very cold all year round. If you live in the Tropic of Capricorn, near the equator, it will be very hot all year round.
