What is the angle at which the sun shines on the ground in winter?

At sunrise, the angle between the sun and the ground is 0/ 180, and at noon, the angle between the sun and the ground is 90, but this is called the noon sun height angle, which is determined by the latitude position of the place and the position of the direct point of the sun. At sunset, the angle between sun and ground is 0/ 180.

1, the specific date is different, and the angle of the sun shining on the ground in the same place is also different.

2. The specific latitude position is different, and the angle at which the sun shines on the ground at the same time is also different.

Therefore, the sun will not shine on the ground at the same angle all winter. Depending on the specific time and place, it is more troublesome to calculate, so there is no need to be so specific.

Law of activity

The direct point of the sun moves westward every hour, passing through longitude 15 degrees every hour. In the calculation of geography problems, we can roughly take the latitude of moving 0.25 degrees every day.

At the vernal equinox, the direct point of the sun is on the equator, and then it moves northward until it reaches the Tropic of Cancer on June 22nd (that is, the summer solstice). 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 23 (autumnal equinox). At the autumnal equinox, the direct point of the sun is at the equator, and then it continues to move southward until it reaches the tropic of Capricorn (that is, the winter solstice) on February 22, 65438. On the solstice in winter, the direct point of the sun is on the tropic of cancer, then it moves northward and returns to the equator on March 2 1 day (that is, the vernal equinox).
