气象资料三维化技术中的插值问题

通过对不同源气象资料及数字地理信息资料的插值，实现了不同气象资料与地理信息资料分辨率的协调；从而将多种信息叠加到一起，实现了多源资料的二维、三维仿真显示。这对于模拟真实的大气空间结构、理解地形及植被对大气运动的影响、辨识各种天气系统及多种信息的融合等有积极意义。     

上海“8.5”特大暴雨的成因和特点

利用WSR－88D多普勒雷达资料，通过分析2001年8月5日到8月6日产生于上海地区的特大暴雨过程的雷达回波特征，研究探讨这次过程的降水成因和降水特点。发现副热带高压边缘偏南气流的风速辐合、螺旋雨带中强回波短带的合并加强、风的垂直切变产生的辐合以及热带系统的高效率降水作用是这次暴雨过程的降水成因和降水特点。并提出了预报这类暴雨系统需要注意的要点：强降水回波的发生和发展加强往往和风场中的局地强辐合区相联系，利用多普勒雷达连续演变的风场资料，可及时了解辐合区的形成和演变过程，提前作出强降水可能性的预测。     

The newest observational evidence on asymmetrical deformation of the Earth

IntroductionWhat is the shape of the Earth? Does it change continuously? It is a scientific question since the ancient times and is still being observed and explored at present. In 250 BC, Greek scholar Eratosthene supposed the shape of the Earth to be spherical according to the observations to the Sun and estimated the perimeter of the Earth to be 4 000 km (King-Hele, 1976) according to the camel-walking distance. Until the 16th century, the Earth was considered to be a very symmetrical …     

2001年四川省雅江-康定6.0级地震烈度考察及发震构造背景雏议

2001年2月23日四川省发生的6.0级地震，其宏观震中位于雅江县与康定县之间的高山峡谷地带．极震区烈度可达Ⅷ 度，Ⅷ 度区、Ⅶ 度区和Ⅵ 度区面积分别为180km2，1472 km2和3998 km2，等震线分布总体形态呈椭圆形，长轴近南北向．震区建筑物普遍受损，极震区山地灾害较为严重．初步分析认为，此次地震的发生与理塘断裂和玉农希断裂的长期活动有关，主干断裂活动造成的地壳应力调整和集中，最终在块体内部的次级断裂上释放而产生地震．

Wind erosion from military training lands in the Mojave Desert, California, U.S.A.

Military training activities reduce vegetation cover, disturb crusts, and degrade soil aggregates, making the land more vulnerable to wind erosion. The objective of this study was to quantify wind erosion rates for typical conditions at the Marine Corps Air Ground Combat Center, Twentynine Palms, CA, U.S.A. Five Big Spring Number Eight (BSNE) sampler stations were installed at each of five sites. Each BSNE station consisted of five BSNE samplers with the lowest sampler at 0·05 m and the highest sampler at 1·0 m above the soil surface. Once a month, sediment was collected from the samplers for analysis. Occurrence of saltating soil aggregates was recorded every hour using Sensits, one at each site. The site with the most erosion had a sediment discharge of 311 kg m⁻¹ over a period of 17 months. Other sites eroded much less because of significant rock cover or the presence of a crust. Hourly sediment discharge was estimated combining hourly Sensit count and monthly sediment discharge measured using BSNE samplers. More simultaneously measured data are needed to better characterize the relationship between these two and reconstruct a detailed time-series of wind erosion. This measured time-series can then be used for comparison with simulation results from process-based wind erosion models such as the Wind Erosion Prediction System (WEPS), once it has been adapted to the unique aspects of military lands.

鞍山市铁矿矿山地质灾害形成条件及对策研究

矿山地质灾害较其它地质灾害相比有其独特性。在鞍山铁矿区，排土场沉降不仅与采矿引起的地下水位下降有直接的联系，还与松散细粒土层、活动断裂有关；滑坡、泥石流地质灾害与地形地貌、水源条件及构造有一定的关系，更重要的是采矿活动产生的废石废渣为其提供了大量的物源；尾矿库灾害主要表现为：洪水漫顶、尾矿砂液化破坏、尾矿坝渗漏及管涌溃堤、尾矿坝滑塌破坏等。本文简要分析了鞍山市铁矿山主要存在的地质灾害类型(排土场地面沉降、滑坡、泥石流及尾矿库地质灾害)和形成条件并提出了防治地质灾害的对策。
