Solar latitude of light snow solar terms

In this way, the solar meridian of each solar term is 15 more than that of the previous solar term, while the solar meridian of the vernal equinox is 0, so the solar meridian of Qingming is 15. By analogy, the relationship between the solar declination (which can be understood as where the direct point of the sun is, the solar declination in the northern hemisphere is+and the solar declination in the southern hemisphere is-) and the solar meridian is SIN δ =. For example, when the longitude of the sun is 3 15 in beginning of spring, then sin δ = sin2326'16 ÷ * sin315, then δ=- 16 20' 6. 18÷ that is.
