快乐无国界

快乐无国界,闭上眼睛,一起快乐享受吧.暑期,老妈带我去日本。我们在上海搭乘了一艘豪华游轮,有十几层楼那么高。船上现代化设施齐全,书店、商场、影城、泳池、餐厅一应俱全。大开眼界的我,快活得像条鱼儿般东窜西钻。老妈焦急的呼唤声哪里追得上我飞奔的脚步声。面对我这匹脱缰的野马,老妈一个劲儿地摇头。不久,我便给老妈吃了颗定心丸,因为我遇见了他们——一对老夫妇.

Primary study on pattern of general circulation of atmosphere before uplift of the Tibetan Plateau in eastern Asia

The Tibetan Plateau is a key factor for the pattern of the general circulation of the atmosphere (GCA) in eastern Asia. The pattern of the GCA after the uplift of the plateau is well known, while the pattern of the GCA before the uplift of the plateau is lack of direct evidences. Based on the knowability of desert, a section recording wind directions across the Cretaceous northern hemisphere mid-low latitude desert belt is measured and the pattern of the GCA in the Cretaceous is revealed. The result shows that the eastern Asia was really controlled by the planetary circulation before the uplift of the plateau, i.e. westerlies in the north and northeast trades in the south. The convert belt between westerlies and trades had drifted northwards and southwards. The possibility of existence of paleo-monsoon is also dealt with and a possibly imposed paleo-monsoon is suggested.
