[1] It is commonly believed that greenhouse-gas-induced global warming can weaken the east Asian winter monsoon but strengthen the summer monsoon, because of stronger warming over high-latitude land as compared to low-latitude oceans. In this study, we show that the surface wind speed associated with the east Asian monsoon has significantly weakened in both(More)
[1] We have applied a scalable and extensible geo-fluid model (SEGMENT) that considers soil mechanics, vegetation transpiration and root mechanical reinforcement, and hydrological processes to simulate two dimensional maps of the landslides occurrence following the 2008 Wenchuan earthquake. Modeled locations and areas generally agree with observations. The(More)
Understanding new particle formation and their subsequent growth in the troposphere has a critical impact on our ability to predict atmospheric composition and global climate change. High pre-existing particle loadings have been thought to suppress the formation of new atmospheric aerosol particles due to high condensation and coagulation sinks. Here, based(More)
Several river systems have their headwaters in the State of Colorado, namely the Colorado River, the Arkansas River, the San Juan River, the South Platte River, the Yampa-White River, the Gunnison River, and the Rio Grande. The management of water resources in these rivers is complex, controversial, and conflicting because of the growth and development in(More)
—Digital elevation model (DEM), as a useful data source for automatic delineation of flow paths, sub watersheds and flow networks for hydrologic modeling, watershed management and environmental assessment, has been much extensively utilized in the multiple-discipline studies. Variety of approaches to delineating flow networks, using different algorithms(More)
Total gaseous mercury (TGM) data from urban Nanjing, at the western edge of the Yangtze River Delta (YRD) region in China, over nine months, were analyzed for peak and background mercury concentrations. The background concentration of TGM was found to be 2.2 ng • m −3. In examining episodic influences of free tropospheric air masses on the surface TGM(More)
Arid and semi-arid areas comprise about 30% of earth surface. Changes in climate and climate variability will likely have a significant impact on these regions. Loess Plateau over Northwest China is a special semi-arid land surface and part of dust aerosol source. To improve understanding and observe the direct evident of the impact of human activity on(More)
