What is the altitude angle of the sun at noon in Zhengzhou? It would be better if there was a calculation process. Besides, where can I find this thing? Please ask the master for advice.

This is geographical knowledge. The midday sun height angle refers to the angle between the sunlight and the ground at noon on a certain day. It is related to several factors, such as local latitude and direct sunlight (related to the season).

For example:

The latitude of Zhengzhou is 34:44 north latitude, which means 34 degrees 44 minutes north latitude. At the vernal equinox (March 20 or 2 1), the direct point of the sun is at the equator of the earth, that is, the latitude is 0.

Then the noon sun altitude angle in Zhengzhou on this day is 90 degrees-34 degrees 44 minutes, which is 55 degrees 16 minutes.
