中文摘要
小行星9510440 本项目将检验热带太阳日射和高纬度冰川作用之间存在非线性联系的假设,这种联系导致了一万年时间尺度上的气候变化。 两个时间段将检查相同的太阳强迫,但不同水平的冰川作用,以比较这两个边界条件的影响。 这项研究可能为控制全球气候变化提供重要的见解。 ***
英文摘要
9510440 Ravelo This project will test the hypothesis that there are nonlinear linkages between tropical solar insolation and high- latitude glaciation resulting in climate variations on the 10,000- year time scale. Two time periods will be examined with the same solar forcing, but different levels of glaciation, in order to compare effects of these two boundary conditions. The study may provide a crucial insight into the controls on global climate change. ***
