The 24 Solar Term·Frost's Descent
二十四节气·霜降
Frost's Descent, (Chinese: 霜降), the 18th solar term of the year, begins this year on Oct.24 and ends on Nov.7. This poetic term for fall's last solar term, is often deemed a prelude to winter as the weather becomes much colder than before and frost begins to appear. For the national average, the Frost's Descent is the period of year with the greatest difference in temperature between day and night.
天气渐寒始于霜降。霜降是二十四节气中的第十八个节气,也是秋季的最后一个节气,它的到来为冬季拉开了序幕。由于“霜”是天冷、昼夜温差变化大的表现,故“霜降”意为“气温骤降、昼夜温差增大”,与“降霜”无关。就全国平均而言,霜降,是一年之中昼夜温差最大的时节。
