Is the winter solstice the coldest day of the year?
The winter solstice is not normally the coldest day of the year. There is actually a lag between the shortest day of the year and the coldest average temperatures, the National Weather Service reports.
"The coldest time usually comes a month or two later because even though the amount of solar heating is beginning to increase, it isn't yet enough to reverse the cooling," Schneider says. "This effect, called 'the lag of the seasons,' is similar to how when you turn down the heat while you're cooking — the pot won't immediately reach its coolest temperature."
Will shadows on the day of the solstice be longer?
Noontime shadows on Thursday will be longest for those of us in the Northern Hemisphere because the sun doesn't rise as high in the sky. The closer you are to the Arctic, the longer the shadows (and the shorter your day) will be.
Why doesn't the earliest sunset come on the shortest day?
The winter solstice may be the shortest day of the year, but that doesn't mean you'll have an early sunset. The exact date of the earliest sunset depends on your latitude, so it's not the same for everyone.
Ancient Chinese people divided 81 days after winter solstice(regarded as coldest time of the year) into 9 parts. Many used "double-nine" diagrams to count the days to spring, either by recording the weather or writing one stroke of a character on a daily basis.
China has developed an unique festive food culture throughout the years. Eating dumplings is a common folk custom for many Chinese on the day of winter solstice, especially those living in the north.
When midwinter comes, vital movement begins to decline and calm down. In this period, eating an appropriate amount of nuts, such as peanuts, walnuts, chestnuts, hazelnuts and almonds, is good for one's body.
