个人认为南极是 study 气候变化的一个综合实验室
那里有变化的洋流,下层的地热,高空的臭氧,再加上复杂的地形的多重影响。
南极98%是陆地,水上的冰是每年几乎都要融化再生:
引用:
Antarctic land ice is the ice which has accumulated over thousands of years on the Antarctica landmass through snowfall. This land ice therefore is actually stored ocean water that once evaporated and then fell as precipitation on the land. Antarctic sea ice is entirely different as it is ice which forms in salt water during the winter and almost entirely melts again in the summer.
文章也承认:暖流的影响还不是很明朗,但是可能与平流层臭氧的减少西风增强有关。
“The influx in warm water onto the continental shelf in this region is not entirely understood but is probably at least partly linked to increased westerly winds that have occured as a result of reduced stratospheric ozone levels since the mid-20th Century”
