Which hemisphere does the sun shine directly at the vernal equinox, summer solstice, autumn equinox and winter solstice?

Direct sunlight at the vernal equinox, summer solstice, autumn equinox and winter solstice is as follows:

1, at the vernal equinox, the direct point of the sun is at the equator, and then it moves northward until it reaches the Tropic of Cancer on June 22 (that is, the summer solstice).

2. On the summer solstice, the direct point of the sun is on the tropic of cancer, and then it moves south until it reaches the equator on September 23rd (autumnal equinox).

3. At the autumnal equinox, the direct point of the sun is on the equator, and then it continues to move south until it reaches the Tropic of Capricorn (that is, the winter solstice) on February 22, 65438.

4. On the winter solstice, the direct point of the sun is on the tropic of Capricorn, then it moves northward and returns to the equator on March 2 1 day (that is, the vernal equinox). The cycle of this repeated regression movement is 365 days, 5: 48: 46, that is, about 365.2422 days, which is called the tropic of cancer.

Law of direct sunlight

Direct sunlight is based on the four seasons of the earth, and different phenomena and influences will appear on the earth due to the movement of the sun's rotation. So we usually say that direct sunlight is the main reason for seasonal changes.

On the day of vernal equinox, the sun shines directly on the equator of the earth, which is the vernal equinox in the northern hemisphere and the autumnal equinox in the southern hemisphere. In March, the equatorial direct sunlight in the northern hemisphere began to move northward; In June, on the tropic of cancer in the northern hemisphere; It began to move south of the equator in September; In June, in the southern hemisphere, on the tropic of cancer.
