Abstract:
The East Asian summer monsoon brings a large amount of precipitation in East China every year, which is the main source of water resources for China. At the same time, it often causes the severe flooding disasters. The Chinese meteorologists and hydrologists have realized that the moisture transport intensity, the extent and persistence of summer monsoon may play a crucial role in extreme rainstorm processes. This branch of moisture transport belt may be termed as the East Asian summer monsoon moisture transport belt. It can be categorized in the atmospheric river (AR) coined internationally, but it is not a fully same conception, due to its unique regional feature of the East Asian summer monsoon. The monsoon moisture transport belt is a main producer of excessively heavy rainfalls and disastrous floods in this region. Based on the data of the past hundred years, this paper made an update review of the characteristics and formation reasons of the East Asian summer monsoon moisture transport belt. Taking the five strongest continuous heavy rain processes in the Haihe River, Yellow River, Huaihe River and Yangtze River in the past hundred years as examples, the important role of the monsoonal moisture transport belt is analyzed. Finally, it is proposed that climate warming can affect the global water cycle through four aspects, including holding more water vapor in the atmosphere, changes of the atmospheric circulations and radiation forcing with climate warming as well as the regional impact of aerosols.

Abstract:
The water vapor transport in the atmosphere is important for the global water cycle, climate system, and ecological environment. The water vapor transport over China is a critical influential factor for the spatial pattern of drought and flood in China. The interannual and interdecadal variability of the water vapor transport over China is affected by the El Niño-Southern Oscillation, sea surface temperature, North Atlantic Oscillation, and Pacific Decadal Oscillation. This paper reviewed recent studies regarding the interannual and interdecadal variability of water vapor transport over China, including the water vapor transport associated with the interannual and interdecadal variability of precipitation in eastern China, the water vapor transport associated with the interdecadal variation of Mei-Yu features, the influences of tropical sea surface temperatures on the water vapor transport over China, and so on. Moreover, the recent advances in water vapor transport over the Tibetan Plateau are also reviewed.

Abstract:
Remote sensing is widely used and plays an irreplaceable role in integrated watershed management and watershed science. This paper focuses on the definition, progress and prospective of watershed remote sensing, and provides a systematic summary of relevant watershed remote sensing data products. Watershed remote sensing studies the analysis capabilities for underlying structure, water cycle, water resources, water hazards and watershed ecology and provides related remote sensing data products. These products are gradually becoming continuously updated public products and services that can meet the requirements for timeliness, completeness, continuity and high accuracy of monitoring information for integrated watershed management. The combination of Watershed remote sensing and cloud computing could reduce the bottleneck of the generation of watershed remote sensing data products. Combined with and cloud services, the difficulty and cost of watershed remote sensing data products application can be reduced, which will be the mainstream direction of watershed remote sensing towards practicality, thus providing comprehensive information support for integrated watershed management.

Abstract:
Air humidity is one of the most important meteorological elements, which is closely related to the temperature and precipitation. Long-term trend of air humidity reflects the change of climate system. According to the third national report on climate change of China, relative humidity over China has demonstrated a sharp decrease around the year 2003, probably due to the substitution of manual stations with automatic stations around the same year. Further research that involves using more data on homogenous relative humidity is required. This study includes daily temperature, precipitation, and relative humidity data corrected by the Meteorological Information Center of China Meteorological Administration and showing good homogeneity at 824 meteorological stations over China during the period from 1961 to 2010. Linear regression analysis, Mann-Kendall trend test and partial correlation analysis methods were used to detect long-term trends of the vapour pressure and relative humidity over China and the impact of temperature and precipitation changes on the trends. The results indicated the following: ① Annual average vapour pressure nationwide is increasing generally, with 90.3% of the stations showing increasing trends. In terms of seasons, vapour pressure mainly exhibits an increasing trend in different seasons across the country, with exception of a decreasing trend in the Loess Plateau and Yunnan-Guizhou Plateau areas and the lower reaches of the Yangtze River basin in spring and summer and in South China in autumn. ② Annual average relative humidity nationwide is generally decreasing, with 64.1% of the stations showing decreasing trends. Stations with increasing trends are mainly distributed as follows:from northern Hebei to northern Liaoning, from southern Shaanxi to Huang Huai, western Sichuan, and most areas of the Northwestern District of China. In terms of seasons, in spring, summer and autumn, the relative humidity in most areas of central and eastern China decreases on the whole, whereas, in winter, most areas show increasing trends except Northeast China and Yunnan which show decreasing trends. ③ The annual average vapour pressure nationwide is mainly positively correlated with the temperature and precipitation, where the positive correlation with the temperature is stronger than that with the precipitation. The annual mean relative humidity is generally negatively correlated with the temperature whereas it is mainly positively correlated with the precipitation.

Abstract:
In this article, we reviewed the history of the development of hydrological science in People's Republic of China for the past 70 years. We also discussed the basic scientific questions of hydrology and its current frontier, which include the hydrosphere and its interface with other spheres of the earth, the hydrological cycle system and the disturbance of human activities to it, the hydro-observation and the methodology of hydrology research, the application of hydrological knowledge, etc. Based on these studies, we suggest to divide the hydrological science into five sub-disciplines:General hydrology, Hydro-meteorology, Land-hydrology, Eco-hydrology, and Applied hydrology.
