冬至：歲末寒至，情暖人間

在漫長(cháng)的歷史歲月里，冬至有著(zhù)諸多不同的稱(chēng)謂。古時(shí)，它曾被稱(chēng)作 “日短” 或 “日短至”，因為這一天是北半球一年中白天最短、夜晚最長(cháng)的日子。還有 “南至” 之稱(chēng)，是由于冬至時(shí)太陽(yáng)直射南回歸線(xiàn)，陽(yáng)光對北半球最為傾斜。此外，像 “長(cháng)至節”“亞歲” 等也是冬至的雅稱(chēng)，“長(cháng)至” 寓意著(zhù)白晝漸長(cháng)，陽(yáng)氣開(kāi)始回升；“亞歲” 則體現出其重要性?xún)H次于除夕，是個(gè)非常關(guān)鍵的時(shí)節。

到了漢武帝時(shí)期，冬至正式定名，并且成為了天文年的起算點(diǎn)。正如漢代史學(xué)家司馬遷在《史記?天官書(shū)》中所記載的 “歲始或冬至日，產(chǎn)氣始萌”，以及在《律書(shū)》里提到的 “氣始冬至，周而復生”，都彰顯出冬至在天文歷法方面的重要意義。

冬至的氣候特征

冬至標志著(zhù)即將進(jìn)入寒冷時(shí)節，民間也由此開(kāi)始 “數九” 計算寒天。但實(shí)際上，冬至之前一般不會(huì )很冷，因為地表尚有 “積熱”，真正的嚴寒是在冬至之后。盡管冬至后太陽(yáng)高度角逐漸升高，可每天散失的熱量大于接收的熱量，氣溫仍會(huì )不斷下降，我國各地氣候也隨之進(jìn)入最為寒冷的階段。

在我國北方地區，冬至后氣溫逐步降到 - 10℃以下，黑龍江北部和內蒙古東部多年平均氣溫低于 - 20℃，大興安嶺以北地區低于 - 25℃，氣候嚴寒，積雪較深；華北地區、秦嶺以南地區則處于 0℃-5℃之間，0℃等溫線(xiàn)穿過(guò)山東丘陵南部 - 秦嶺 - 橫斷山脈一帶；華南和云南南部氣溫相對較高，在 10℃-19℃之間，不過(guò)氣溫同樣會(huì )持續降低。

同時(shí)，冬至時(shí)節寒潮活動(dòng)頻繁，北方地區寒冷加劇，南方也能明顯感受到寒意，大部分地區的最低氣溫都會(huì )下降到冰點(diǎn)以下。并且由于冬季空氣濕度較低，天氣往往比較干燥，人們的皮膚容易干裂，需要做好保濕工作。此外，這個(gè)時(shí)節還多伴有陰冷多霧、多風(fēng)少雨的情況，陽(yáng)光照射時(shí)間短暫，氣溫低，在江河湖海等水體附近，水汽容易凝結成霧，導致能見(jiàn)度降低，而雨水相對較少，氣壓差異增大，風(fēng)力相對較強，北方多為偏北風(fēng)和偏東風(fēng)，南方則以東南風(fēng)和東北風(fēng)為主。

冬至的傳統習俗

（一）北方習俗

冬至時(shí)節，北方有著(zhù)諸多別具特色的傳統習俗，其中最具代表性的當屬吃餃子了。北方地區流傳著(zhù) “冬至不端餃子碗，凍掉耳朵沒(méi)人管” 的說(shuō)法，餃子在這一天可是餐桌上必不可少的美食。

而且呀，餃子里包不同的餡料還蘊含著(zhù)各種各樣美好的寓意呢。比如西紅柿雞蛋餃子，西紅柿雞蛋搭配在一起，味道獨具風(fēng)味，寓意著(zhù)紅紅火火，為生活增添一抹亮色；白菜豬肉餃子也是經(jīng)典餡料，“白菜” 與 “百財” 諧音，象征著(zhù)財源滾滾進(jìn)家門(mén)，承載著(zhù)人們對財富的美好期許；牛肉洋蔥餃子很受歡迎，牛肉有著(zhù)牛氣沖天的寓意，吃著(zhù)這餃子，仿佛來(lái)年做什么都干勁十足；寒冷的冬至，來(lái)上一份羊肉胡蘿卜餃子再合適不過(guò)了，它寓意著(zhù)喜氣洋洋，給這個(gè)節氣增添了幾分歡快的氛圍；還有韭菜豬肉餃子，韭菜寓意長(cháng)長(cháng)久久，飽含著(zhù)人們對親情、友情、愛(ài)情長(cháng)久的祝愿。

除了吃餃子，在部分北方地區還有宰羊的習俗，冬至時(shí)吃羊肉既能滋補身體，又可以抵御嚴寒，一家人圍坐在一起，品嘗著(zhù)鮮美的羊肉，其樂(lè )融融，盡顯冬至的熱鬧與溫馨。這些獨特的習俗展現出了北方冬至濃郁的風(fēng)情，承載著(zhù)人們對美好生活的向往與期盼。

（二）南方習俗

南方人過(guò)冬至同樣有著(zhù)豐富多彩且極具地方特色的習俗。吃湯圓便是南方大部分地區的傳統食俗，“湯圓” 是用糯米粉制成的圓形甜品，“圓” 意味著(zhù) “團圓”“圓滿(mǎn)”，所以冬至吃湯圓又叫 “冬至團”，民間還有 “吃了湯圓大一歲” 的說(shuō)法，大家在這一天會(huì )自己做或者去市場(chǎng)上買(mǎi)湯圓來(lái)吃，希望家庭幸福美滿(mǎn)，團團圓圓。除了湯圓，像冬至米團、冬至長(cháng)線(xiàn)面等也常常出現在南方人的冬至餐桌上，每一樣都承載著(zhù)濃濃的節日氛圍。
