Calculation method of solar angle of winter solstice in Shanghai

In China, the influence of climate on culture cannot be ignored. Throughout the formation and development of China culture, it is not difficult to find that in the process of cultural development, the climate constantly interferes with the pace and direction of culture. Specific atmosphere will produce specific changes in solar terms, food culture, clothing culture and so on. Then, from the perspective of Shanghai culture, let's calculate the solar altitude angle from winter solstice in Shanghai.

Shanghai has a subtropical humid monsoon climate with four distinct seasons, abundant sunshine and rainfall. Shanghai has a mild and humid climate, short spring and autumn, warm winter and cool summer. 65438+ 10 is the coldest month with an average temperature of about 4℃, and it is usually the hottest in July with an average temperature of about 28℃.

Calculation formula of solar altitude angle at noon in Shanghai;

H = 90°- Latitude difference between two places (two places refer to the latitude difference between Shanghai and the direct point of the sun)

1 If the latitude difference between the two places is in two hemispheres, add it, and if it is in the same hemisphere, subtract a big block.

The latitude of Shanghai is roughly 3 1 north latitude.

In winter solstice, the tropic of Capricorn is 90-(3 1+23 26') = 35 34'

According to the above method, we know that the solar altitude angle of the winter solstice in Shanghai is 35 34'. You got it?
