从 2 0世纪初开始 ,在夏季日照变化显著的北半球高纬地区 ,可以发现日照和气候之间的联系 ,通常认为夏至期间在 6 5°N的大气层顶部 (TOA)的日照反映了使全球气候变化的太阳引力。这里与Berger等 ( 1 981 )的结论进行商讨 ,他们将两个半球不同纬度大气层顶部日照的月变化与Hays Beginning in the early 2000s, the link between sunlight and climate can be found in the high latitudes of the northern hemisphere, where the summer sunshine varies significantly, and it is generally assumed that the sunshine over the TOA at 6 5 ° N during the summer solstice reflects a shift in the global climate Changing solar attraction. Here we discuss Berger et al.’s (1981) conclusion. They compare the monthly change of the sunshine at the top of the two latitudes with the latitude of the Hays
