作者： Zhili Wang1, Hua Zhang2, Zaizhi Wang2, Xiaoye Zhang1 and Sunling Gong11 Chinese Academy of meteorological Sciences, No. 46 Zhongguancun Nandajie Haidian District, Beijing, china, 100081 2 National Climate Center, china meteorological administration, No. 46 Zhongguancun Nandajie Haidian District, Beijing, china, 100081

Aerosol indirect effects (AIEs) on global climate are quantitatively investigated by introducing aerosol-cloud interaction parameterizations for stratus clouds into an AGCM (BCCGCM2.0.1) developed by the National Climate Center of the china meteorological administration coupling with the Canadian Aerosol Module (CAM). The study yields a global annual mean of -1.57 W m-2 for the first indirect radiative forcing. The second indirect effect leads to global annual mean changes in net shortwave flux of -0.58 W m-2 at the top of the atmosphere (TOA). The total AIE reduces the global annual means of net shortwave flux at the TOA and of surface temperature by 2.27 W m-2 and 0.12 K, respectively. Change in surface temperature induced by the total AIE is clearly larger in the Northern Hemisphere (-0.21 K) than in the Southern Hemisphere, where changes are negligible. The interhemispheric asymmetry in surface cooling results in significant differences in changes of the interhemispheric annual mean precipitation rate, which could lead to a tendency for the ITCZ to weaken and broaden. In summer, the northeasterly or northerly flows in most areas of east and south china and over the nearby oceans are enhanced due to the total AIE, which weakens the transport of warm and moist air carried by the East Asian summer monsoon, and decreases the summer monsoon precipitation in east and south china.

Because of the large number and remoteness, satellite data, including microwave data and optical imagery, have commonly been used in alpine glaciers surveys. Using remote sensing and Geographical Information System （GIS） techniques, the paper presents the results of a multitemporal satellite glacier extent mapping and glacier changes by glacier sizes in the Mt. Qomolangma region at the northern slopes of the middle Himalayas over the Tibetan Plateau. Glaciers in this region have both retreated and advanced in the past 35 years, with retreat dominating. The glacier retreat area was 3.23 km2 （or o.75 km^2 yr^-1 during 1974 and 1976, 8.68 km^2 （or 0.36 km^2 yr^-1 during 1976 and 1992, 1.44 km^2 （or 0.12 km^2 yr^-1） during 1992-2ooo. 1.14 km^2 （or 0.22 km^2 yr^-1 during 2000-2003, and 0.52 km^2 （or 0.07 km^2 yr^-1 during 2003-2008, respectively. While supra-glacier lakes on the debris-terminus of the Rongbuk Glacier were enlarged dramatically at the same time, from 0.05 km^2 in 1974 increased to 0.71 km^2 in 2008, which was more than 13 times larger in the last 35 years. In addition, glacier changes also showed spatial differences, for example, glacier retreat rate was the fastest at glacier termini between 5400 and 5700 m a.s.l than at other elevations. The result also shows that glaciers in the middle Himalayas retreat almost at a same pace with those in the western Himalayas.

Coastal water environment is essentially enhanced by ocean color which is basically decided by substances concentration in water such as chlorophyll, suspended material and yellow substance. It is very difficult, even not possible, to detect water color by expensive ship routing, because of its temporal and spatial variety of feature and scales in the very complicated dynamical system of coastal water. With the development of satellite technique in the last 20 a, space sensors can be applied to detect ocean color by measuring the spectra of water leaving *** is proven that ocean color remote sensing is a powerful tool for understanding the process of oceanic biology and physics. Since the 1980s, great attention has been paid to the advanced remote sensing technique in china, especially to development of satellite programs for the coastal water environment. On 7 September 1988, china launched her first polar orbit satellite FY-1A for meteorological and oceanographic application (water color and temperature) and the second satellite FY-1B two years later. In May 1999, china launched her second generation environment satellite FY-1C with higher sensitivies, more channels and stable operation. The special ocean color satellite HY-1 is planned to be in the orbit in 2001, whose main purpose is to detect the coastal water environment of china seas. china is also developing a very advantageous sensor termed as Chinese moderate imaging spectra radiometer (CMODIS) with 91 channels, which will be a good candidate of the third generation satellite FY-3 in 2003. The technical system of ocean color remote sensing was developed by the Second institute of Oceanography (SIO), State Oceanic administration (SOA) in 1997. The system included data receiving, processing, distribution, calibration, validation and application units. The Hangzhou Station of SIO, SOA has the capability to receive FY-1 and AVHRR data since 1989. It was also a SeaWiFS scientific research statio
