Do you think whether the West Lake is frozen or not can be used as a criterion to measure whether it is cold or not?

I think whether the West Lake is frozen or not can be used as a criterion to measure whether it is cold or not. Because it doesn't mean that the lake can freeze when the temperature reaches zero, and it can't freeze when the temperature reaches zero. Only the continuous low temperature will cause the lake to freeze. The lower the temperature, the thicker the ice layer.

Recently, various places have been hit by cold waves, and even the Hangzhou Meteorological Observatory has issued cold warning and low-temperature orange warning signals. There is ice on the surface of the West Lake, and even the chairs and vegetation around the lake are hung with ice.

We know that in theory, the lake begins to freeze when the temperature reaches 0℃, but when the temperature reaches 0℃, the water temperature has not reached 0℃. So whether the water surface will freeze is related to the duration of low temperature. Of course, if the temperature is lower and lasts longer, the ice will be thicker. The temperature in Hangzhou has been below 0℃, with the lowest temperature reaching -7℃ and the lowest temperature in mountainous areas reaching-1 1? This is the lowest temperature in Hangzhou since winter, which eventually led to the freezing of the West Lake. Don't say that the West Lake is frozen, even everyone's towels are frozen. Although it is not the first time that the West Lake freezes, it has been stuck at zero before, so it is a very thin layer of ice, which basically melts quickly and can be ignored.

In the history of Hangzhou, 1997, 199 1 and 2008, the freezing was very serious, and the lowest temperature in Hangzhou was -8.6℃. It is said that skating can be done on the West Lake. Moreover, the West Lake froze in 1977, and a thick layer of ice was formed after more than days of low-temperature freezing in 10. It should be an old saying that Rome was not built in a day. Many friends said that this scene is very familiar and unfamiliar. The last time it happened was when they were young, which gave them a sense of childhood familiarity. But because it hasn't happened for so long, it feels strange. When they saw the ice, they remembered the scene of pushing it down with a bamboo pole when they were children. It seems that the ice in the West Lake really shows that Hangzhou is getting cold this time.
