Heavy snow in solar terms is suitable for eating.

It is suitable for eating mutton because of the heavy snow in solar terms.

"Twenty-four solar terms" said: heavy snow, November Festival, has always been heavy snow, because snow is the product of cold, representing cold and rainy weather. This solar term is characterized by a significant drop in temperature, and strong cold air can often bring rainfall or snowfall. The name heavy snow is a metaphor, which reflects the climate change during this solar term. The cold current is active, the temperature drops and the precipitation increases. It's not that it snows heavily in this solar term, but that it will get colder and colder after the solar term.

The heavy snow in the sense of solar terms is not necessarily related to the heavy snow described in the weather forecast. Snow solar term is a climate concept, which represents the climate characteristics during the snow solar term. The heavy snow in the weather forecast refers to the snow with high snowfall intensity. According to meteorology, the snowfall with poor visibility, horizontal visible distance less than 500 meters, ground snow depth equal to or greater than 5 cm, or snowfall between 5.0 and 9.9 mm within 24 hours is called heavy snow.

Meteorological change

The meaning of solar terms and heavy snow is different from that of weather and heavy snow. In fact, the snow in solar terms is often not as big as light snow. The solar terms with the largest snowfall in the whole year are not light snow and heavy snow, such as the middle and lower reaches of the Yellow River. The solar terms with the largest snowfall in the whole year are neither light snow, heavy snow nor slight cold (because the temperature was low at that time and there was less water vapor in the atmosphere), but spring rain.

The reason why heavy snow is not the biggest is similar to light snow, that is, the coldest period of the year has passed in late February of the Gregorian calendar. In early spring, the warm air in the south began to be active and the water vapor began to be rich. At this time, the cold air force in the north is still very strong, and the warm air flow rises strongly and persistently on the back of the dense cold air flow, which may lead to heavy snow. There is no necessary connection between solar terms and heavy snow.
