The horizonial resolution is 5° lat. ×5° long. with the integration region from 25°S to 55°N and from 5°W eastward to 175°W. The model was spun up with perpetual June boundary conditions and forcing starting with June zonal mean heights and geostrophic wind field. In order to investigate the effects of SST (sea surface tempefuture) over the equatorial Western Pacific and the Indian Ocean on the Asian summer monsoon, four sets of numerical experments with positive anomalies over the equatorial Western Pacific, and positive and negative anomalies over the Western Indian Ocean, and zonal mean SST (the control case) are performed. The experimental results show that the South Asian low in the lower troposphere and the anticyclone over the South Asia in the uppet troposphere intensified when positive SST anomalies over the equatorial Western Pacific is included. A statistical test method for simulations is proposed. Finally, the influence mechanism of the SST anomalies over the equatorial oceans is discussed. It is worth stressing that the effects of the SST over the equatorial oceans on the Asian summer monsoon can arise as a result of interaction of SST anomalies, atmospheric flow field and heat sources and sinks in the atmosphere.展开更多

Both the method and the program, verified by a numerical frictional experiment composed of two blocks, are correct and reliable. Simultaneously, using this program, the present velocity field of the eastern Asia area, which is induced by the collision of the Indian shield against the Asian plate, is investigated. The primary result shows that the velocity field in magnitude is largest near the colliding boundary and attenuates fast away from it. The Tibet plateau moves northeast, the North China plain and the southeastern Asia moves eastward and southeastward, respectively. The attenuation of the velocity field across Qilianshan is nonlinear, its direction changes from the northeast nearly to the east, its gradient is 0.05 mma-1km-1 and 0.007 mma-1km-1 to the southwest and the northeast of Qilianshan, respectively. The attenuation of the velocity field is almost linear across the Longmenshan fault, its gradient is 0.01 mma-1km-1 and its direction is toward the southeast. The remarkable deformation caused by collision extends to the east longitude 115 and to the north latitude 45. The velocity field obtained by the method is basically consistent with the data from the Global Positioning System. The relative slip rate along the Bangong-Nujiang-Lancangjiang fault is 0.5 mm/a, the Jinshajiang fault, 0.8 mm/a, while the Tanlu fault hardly moves. It is shown that the method proposed in this paper could be employed to study the geodynamic problems with faults.展开更多

Objective criteria for choosing the most appropriate climate parameter（s） to be reconstructed at a specific site are thus lacking. Using a novel approach for testing the statistical significance of a quantitative reconstruction using random environmental data, in combination with the advantageous large environmental gradients, abundant vegetation types and comprehensive modem pollen databases in China, we describe a new procedure for pollen-based quantitative paleoclimatic reconstructions. First, the most significant environmental variable controlling the fossil pollen assemblage changes is identified. Second, a calibration set to infer changes in this targeted variable is built up, by limiting the modem ranges of other environmental variables. Finally, the pollen-based quantitative reconstruction is obtained and its statistical significance assessed. This novel procedure was used to reconstruct the mean annual precipitation （Pann） from Gonghai Lake in the Lvliang Mountains, and Tianchi Lake in the Liupan Mountains, on the eastern and western fringe of the Chinese Loess Plateau, respectively. Both Pann. reconstructions are statistically significant （p〈0.001）, and a sound and stable correlation relationship exists in their common period, showing a rapid precipitation decrease since 3300 cal yr BP. Thus, we propose that this procedure has great potential for reducing the uncertainties associated with pollen-based quantitative paleoclimatic reconstructions in China.展开更多
