Characteristics And Changes Analysis On Water Vapor Transportation In Xinjiang

Useing the U.S. Centers for Environmental Prediction and the EuropeanCenter for Environmental Prediction download NCEP2.5°×2.5°reanalysisdata and NCEP1°×1°reanalysis data and observation points in Xinjiang forradiosonde data and the measured ground-based observations of the groundstation data, through the analysis of water vapor transmission characteristics ofXinjiang, where the main to the water vapor transport in the process of watervapor content and vapor flu wascalculated, and basic meteorological statisticalmethods Mann-kendall and EOF method anbilinear interpolationsuddentheoretical formula, empirical formula and other methods of its characteristicsand change the analysis results show that:1、Xinjiang in the arid, semi-arid areas, the region covered mountains, lakes,glaciers, frozen soil, forest vegetation and desert, influenced by terrain, the centerof the high value of the water vapor content in this area.2、Xinjiang region of arid and semiarid area, from the direct impact of themonsoon, water vapor transport in the spatial distribution of the Tarim Basin andJunggar Basin to the high value area, the Altay, Tianshan and Kunlun Mountainsand the northern Xinjiang, Inner Mongolia and MongoliaThe regional water vaportransport for the low value area.3、From the space distribution of atmospheric water vapor content in Xinjiangsee, throughout the year in the spring, the water vapor content in the autumn thanin winter, summer, water vapor content value.4、the dynamic conditions, the moisture convergence and other factors,differences in the decision of precipitation in Xinjiang, and the water vaporcontent and precipitation spatial distribution of different, less precipitation in alarge water vapor content. Observation stations in the radiosonde data and NECPreanalysis data analysis was consistent with the Xinjiang water transportationconditions.5、Xinjiang, Siberia, Mongolia, the direction of the northwest wind vaporconveyor paths to reach the Atlantic westerly water vapor conveyor belt and theBay of Bengal to the southwest of the southern Xinjiang Wind vapor conveyorbelt; Xinjiang winter westerly water vapor conveyor-based, in southern XinjiangTarim Basin to the southwest warmthe impact of the wet gas flow based. Thedata analysis shows that theair vapor transport of the Xinjiang region in the1980s, mainly from themeridional transport of zonal transportation increase, while the1980s.
