45 degree oblique weather
Better change 23.5 to 28, because I'm still free.
Suppose 45 degrees:
1, beyond 45 degrees, there will be no extreme day and night).
2. It became tropical from 45 south latitude to 45 north latitude. But this tropical area is not hot. The average temperature drops.
3. The cold zone has disappeared. (Baidu Encyclopedia Cold Zone Definition: Definition: Astronomical High Latitude Zone. Extreme days and nights are everywhere in the polar circle of the northern and southern hemispheres, that is, the circular zone with latitude higher than 66 33', and their duration increases with the increase of latitude. ), because extreme day and night will disappear.
4. Principle: The total energy emitted by the sun to the earth is constant. What changes is only the uniformity of distribution. Our current inclination is 23.26-the sun only shines from 23.26 in the south to 23.26 in the north all the year round-this small area is hot, such as Singapore, Australia and Hainan-it is warm all the year round. . From Hunan to Beijing, the four seasons are quite distinct. If it becomes 45 degrees-the sun always shines from south to north-it is also 23.26 degrees to 45 degrees a year, and the tropical area increases and the time remains the same. The time the sun stays in each small area is shortened, and the energy obtained at each point is reduced-the reduced part is distributed to high latitudes.
The advantage is that it is not so hot in the south and not so cold in the north (this is the key! ! ! ), the rainfall and weather temperature in the north and south of the Yangtze River are relatively more uniform-the desert has become an oasis-of course, tropical plants that need strong light cannot grow well-typhoons in Asia and hurricanes in Europe have been greatly reduced-the four seasons are no longer distinct-the earth is no longer colorful!
6. The biggest disaster is the melting of polar glaciers! ! ! Sea level rise! ! ! ! Coastal cities fall! ! ! !
7. If the solution becomes 90 degrees-then the other pole will never see the sun-the earth will die! ! ! !
