On the basis of basic characteristics of Equatorial Pacific atmosphere and ocean, we designed a simple air-sea coupled model. Using this model,an ocean circulation was simulated. The east-west oscillation of sea temperature in Equatorial Pacific is related to this ocean circulation.展开更多

In the past eight years,China has seen the gap between eastern and western regions still widening while also taking on the arduous task of protecting nature,ecology and environment in the western region. How has western development fared in the past eight years? What difficulties and challenges are being encountered? The development of the western region poses the single greatest difficulty facing China's regional economic development,but how can we advance along a "sound and fast" development path? The establishment of economic zones in Chengdu and Chongqing,Guanzhong and North Bay has opened up new possibilities and expectations for western China's economic development.展开更多
