Wind energy has been rapidly developed in China during the past decades and the installed capacity has been the largest in the world. In the future, utilization of wind power is still expected to carry out in China mainly with a large-scale centralized layout. Here, we examine the potential climatic impacts of large-scale windfarms associated with deployment scale in China using numerical experiments, in which four deployment scenarios were designed. These four scenarios represented relatively small- (484 GW), medium- (2165 GW) and large-scale (3490 GW and 5412 GW) installed wind power capacities, respectively. Results showed that turbulent kinetic energy, wind velocity, and air temperature varied consistently within those windfarms with the largest changes in turbine hub heights. Moreover, the above relatively large- scale windfarms could induce regional wanning with a maximum of above 0.8 °C in North China. This regional warming may be linked to an anomalous circulation pattern with a negative pressure anomaly center in Northeast China and a positive pressure anomaly center in the middle and lower reaches of the Yangtze-Huaihe River Basin.

There is scientific progress in the evaluation methods of recent Earth system models(ESMs).Methods range from single variable to multi-variables,multi-processes,multi-phenomena quantitative evaluations in five layers(spheres)of the Earth system,from climatic mean assessment to climate change(such as trends,periodicity,interdecadal variability),extreme values,abnormal characters and quantitative evaluations of phenomena,from qualitative assessment to quantitative calculation of reliability and uncertainty for model *** started considering independence and similarity between models in multi-model use,as well as the quantitative evaluation of climate prediction and projection efect and the quantitative uncertainty contribution *** this manuscript,the simulations and projections by both CMIP5 and CMIP3 that have been published after 2007 are reviewed and summarized.

Most model generated projections of climate change for the future decades only consider anthro- pogenic activities. It is hard to think about the effects of solar activity and volcano effects, because the pre- dictions of both solar activity and volcano effects are difficult. But as we know, the sun is the source of en- ergy for the Earth＇s climate system, and observations show it to be a variable star.

Wormhole-like mesostructured H3PW12O40/TiO2 composite catalyst was prepared by the combination of sol-gel chemistry and solvothermal treatment technique in the presence of a triblock copolymer surfactant. Results of Raman spectra, XRD, BJH pore distribution and TEM image indicate that the composite possess a three- dimensionally interconnected pore mesostructure with a high porosity and large pore size. Keggin units were homogeneously dispersed throughout the composite. This composite can catalyze the photodegradation of crystal violet （CV） under visible-light. The photocatalytic activity is much higher than that of pure TiO2 or H3PW12O40/TiO2 composite prepared in the absence of the surfactant.

The United Nations world urbanization prospects 2009 report points out, that at present more than 50% of the world＇s population is living in urban area, and it is expected that by 2050 this figure will reach 70% [UN, 2009]. Therefore, there is need to pay more attention to the impacts of urban heat island effects on future climate change.
