why is it colder than before after the winter solstice in 2020? Although the sun is moving north after the winter solstice, the sun is still in the southern hemisphere, the solar height in the northern hemisphere is still very low, and the solar radiation in the northern hemisphere is still less than the ground radiation, so the heat obtained by the ground is still less than the heat lost by the ground radiation, and the ground temperature is still decreasing, The temperature is also falling, so it will continue to cool after the winter solstice, and it will be colder. Until the sun's straight point moves north to a certain position, that is, when the solar radiation in the northern hemisphere is greater than the ground radiation, the northern hemisphere begins to warm. From the 24 solar terms, we can see that there is a slight cold after the winter solstice, and then a severe cold. The severe cold is the coldest time of the year.
