根據中國天(tian)氣網消息，因為(wei)(wei)北(bei)方水汽和天(tian)空云量較(jiao)少(shao)，更容易得(de)太陽青睞。2022年(nian)全(quan)(quan)國日照時間最(zui)(zui)長十大城(cheng)市(shi)(shi)(shi)(shi)均(jun)為(wei)(wei)北(bei)方城(cheng)市(shi)(shi)(shi)(shi)，其(qi)中包頭市(shi)(shi)(shi)(shi)摘得(de)榜(bang)首；2022年(nian)全(quan)(quan)國日照時間最(zui)(zui)短十大城(cheng)市(shi)(shi)(shi)(shi)均(jun)為(wei)(wei)南方城(cheng)市(shi)(shi)(shi)(shi)，成都(dou)市(shi)(shi)(shi)(shi)排名首位。

以一天平均有12小時(shi)最(zui)(zui)大日(ri)照(zhao)時(shi)數換(huan)算，北方日(ri)照(zhao)時(shi)間(jian)最(zui)(zui)長十大城(cheng)市(shi)的日(ri)照(zhao)總(zong)時(shi)長約為南方這十個日(ri)照(zhao)時(shi)間(jian)最(zui)(zui)短城(cheng)市(shi)日(ri)照(zhao)總(zong)時(shi)長的兩倍(bei)。
