What happens when it hails in leap February?

The temperature is too low in February.

Hail in leap February is not common, because leap month is equivalent to destroying the periodicity of the lunar calendar. Hail usually appears in hot and rainy summer and spring. If there is really hail in February, it may have a great impact, such as damage to crops, damaged houses, traffic jams and so on. At the same time, it will also arouse people's attention and research on weather and climate change, and explore its causes in order to better understand weather and hydrology.

Leap moon is actually very common. It is the lunar calendar that absorbs the solar terms of the trunk calendar as a supplement to the calendar and adjusts it to conform to the tropic year through the leap method, forming a combined calendar of yin and yang. By "setting leap", the average length of a Gregorian calendar year can be equal to about a solar year, which is roughly consistent with the natural season and avoids being out of touch with the four seasons.

According to the agricultural proverb summarized by the ancients above, the temperature will be lower than normal this spring, and it will be drier in autumn. The low temperature in spring will have a certain impact on sowing. Because of the low temperature, seeds can not emerge after sowing, and the seeds are easy to rot. Therefore, we should postpone sowing. But we know that crops need a certain accumulated temperature from germination to maturity, and the accumulated temperature is not enough, which affects grain plumpness and final yield. Therefore, if the best sowing date is missed. Only early-maturing varieties can be changed.
