What is the angle of the height of the sun at noon between the vernal equinox and the autumnal equinox?

At the vernal equinox and autumnal equinox, the altitude angle of the sun is 50, and it is 73 26 ′ in summer solstice and 26 34 ′ in winter solstice.

The solar altitude angle at noon changes regularly with different latitudes and seasonal changes. At the same latitude, the midday sun height angle changes with the seasons. For example, in Beijing (39 54' north latitude), the summer solstice is the highest and the winter solstice is the lowest, and the dichotomy is moderate. In the same season, the midday sun height angle varies with latitude. The higher the latitude in summer, the greater the angle of the sun. In winter, the higher the latitude, the smaller the angle of the sun.

From summer solstice, the sun shines directly on the Tropic of Cancer, and the solar altitude angle north of the Tropic of Cancer reaches the maximum value in a year, and the whole southern hemisphere reaches the minimum value in a year. On the contrary, when shooting the tropic of Capricorn directly, the solar altitude angle south of the tropic of Capricorn reaches the maximum in a year and the minimum in the whole northern hemisphere. On the solstice in winter, the height angle of the noon sun gradually decreases from the tropic of Capricorn to the north and south poles.
