Rivers in the Liaohe River Estuary area have been seriously polluted by discharges of wastewater containing petroleum pol- lutants and nutrients. In this paper, The Enhanced Stream Water Quality Model (QUAL2K) and its revised model as well as One-dimen

Based on a monthly dataset of precipitation time series (1961-2010) from 12 meteorological stations across the Three-River Headwater Region (THRHR) of Qinghai Province, China, the spatio-temporal vari
风沙活动和降雨是引发干旱-湿润过渡区水土流失和一些环境问题的主要根源。本文基于气象站记录的沙尘暴和降雨量资料,利用ArcGIS 9.2软件,采用累积曲线和累积距平百分率等方法分析了黄土高原地区近50年(1958-2007年)沙尘暴日数和降雨量的时空变化。结果表明:(1)年内分布不均,沙尘暴主要发生在春季,占到全年的54%,降雨主要集中在汛期,占到全年的71%;(2)近50年年沙尘暴日数呈明显减少趋
雷达资料可以直观地显示雷暴降水过程随时间变化风场的垂直结构以及各高度层风向风速随时间变化特征,能较好地监测到低空急流以及降水粒子的垂直速度。利用风廓线雷达探测资料对2010年7月12日塔中一次雷暴降水过程中的边界层三维风场进行分析研究。结果表明:雷暴降水过程低层风速增大,高层风速减小;上空存在低空急流,平均风速达17.1m.s-1;雷暴时段,下沉气流垂直速度3.0m.s-1左右;降水时段,降水粒子
The paper presents results of a study on the sediment supply and movement of highly turbid sediment plume within Malindi Bay in the Northern region of the Kenya coast. The current velocities, tidal el
利用NCEP/NCAR再分析春季逐月平均位势高度、风、温度、垂直速度等物理量的格点资料,通过图形分析技术进行天气系统识别,建立3类宁夏春季干旱多层次环流概念模型,并对各类型主要影响因子进行特征量对比计算,得出了宁夏春季干旱监测预测定量化指标。在如下条件下,宁夏易发生春季干旱:(1)500hPa东亚大槽位于120°—140°E,其中位于120°—130°E间时发生的干旱强度最大,偏东或偏西则强度减弱
Zhongshan HF radar, as one component of SuperDARN, has been established and in operation since April, 2010. Using data from the first two years of its operation, this paper investigates the radars per
The Energization and Radiation in Geospace (ERG) mission seeks to explore the dynamics of the radiation belts in the Earths inner magnetosphere with a space-borne probe (ERG satellite) in coordination
We report on the characteristics of nighttime medium-scale traveling ionospheric disturbances (MSTIDs) propagating northward observed with the SuperDARN Hokkaido HF radar, which has a field of view to
This is an empirical paper that measures and interprets the position of Chinese cities in the world city network in 2010. Building on a specification of the world city network as a′interlocking networ
Globalization and informatization have accelerated city networking process over the world, which makes research on city network a hot topic in the fields of urban geography and economic geography. Wit
