长江三角洲地区水和热通量的时空变化特征及影响因子

文中利用改进的K B模式和牛顿扩散方法及 196 1年以来的长江三角洲 (2 8～ 33°N ,118～ 12 3°E)地区的 4 8个测站的常规气象资料 ,估计了该地区近 4 0a来的蒸散量和感热通量。结合该地区的气温、太阳辐射等气候资料和 196 0年以来该区域土地资源利用变化等有关信息对该地区的潜热通量和感热通量的时 空间变化特征及其可能成因进行了综合分析。结果认为该地区自 2 0世纪 70年代开始平均蒸散量有逐渐减小的趋势 ,与 1980年相比 ,1998年区域年平均蒸散量减小了 2 4mm。区域平均感热通量与蒸散量相比在此期间变化并不明显。通过对该地区的云量、太阳辐射及土地利用变化资料分析认为 ,造成该地区平均蒸散量减少趋势的的原因之一是用于蒸发的能量即太阳辐射的减少 ,而造成太阳辐射减少的可能原因为云量及大气透明度的变化所至 ;原因之二是该地区地表覆盖条件的改变。近 2 0a来 ,该地区的水田、旱地及水域面积占总面积的比率分别减少 1.35 3% ,4 .4 4 2 %和2 .5 97% ,而城镇建设、工矿及其它建设用地面积则增加 3.345 %。耕地及水面的减小和城镇及建设用地面积的增加从整体上使区域平均蒸发量减少。     

西藏地区旱涝等级划分及时空分布特征

利用西藏22个站点1969-1998年逐日降水资料，采用d指数旱涝等级方法。按夏季（5-9月），初夏（5-6月），盛夏（7-8月）时段进行了旱涝等级划分。采用EOF分析方法对全区22个站点旱涝等级展开分解，得出西藏地区的旱涝时空分布特征，主要类型和周期，而且对西藏地区夏季（5-9月）的旱涝做了预测。     

一种短期气候预测集成技术的应用研究

以递归正权综合决策方案为基础，结合实际情况，首先对多种预报方法进行筛选，选取预报效果较好并且较为稳定的几种方法参与集成，并将集成结果写成Micaps数据格式，最终以图形方式显示出来。评分结果表明：该集成方法对温度预报和灾害指数预报较权重平均集成法效果好；而对月雨量预报和季度雨量、温度预报则与权重平均方法相当；但是对季度雨量、温度预报来说，集成后预测精度有明显提高。同时，将集成结果通过Micaps工作平台以图形方式显示，不仅客观、定量，而且更一目了然．     

NWP在颠簸预报中的应用

颠簸是航空气上重要预告内容之一，历史上由于颠簸引起的飞行事故及征候占有一定的比例，颠簸预报也是气象预报的难点，颠簸对飞行的影响至关重要，轻则引起航行中的飞机摆动偏航，重则造成飞机解体，近年来随着太原机场卫星广播传真数值预报产品的使用，我们也在逐步尝试使用数值产品分析颠簸，使颠簸的预报有了明显提高。     

Damaging properties of ground motions and prediction of maximum response of structures based on momentary energy response

Dynamic damaging potential of ground motions must be evaluated by the response behaviour of structures, and it is necessary to indicate what properties of ground motions are most appropriate for evaluation. For that purpose, the behaviour of energy input process and hysteretic energy dissipation are investigated in this study. It is found that the momentary input energy that is an index for the intensity of input energy is related to the characteristics of earthquakes such as cyclic or impulsive, and to the response displacement of structures immediately. On the basis of these results, a procedure is proposed to predict inelastic response displacement of structures by corresponding earthquake input energy to structural dissipated damping and hysteretic energy. In this procedure the earthquake response of structures is recognized as an input and dissipation process of energy, and therefore structural properties and damaging properties of ground motions can be taken into account more generally. Lastly, the studies of the pseudodynamic loading test of reinforced concrete structure specimens subjected to ground motions with different time duration are shown. The purpose of this test is to estimate the damaging properties of ground motions and the accuracy of the proposed prediction procedure. Copyright © 2002 John Wiley & Sons, Ltd.     

神头泉流量变化规律研究--灰色系统理论的具体应用

在分析神头泉流量衰减特征的前提下，利用灰色系统理论建立了描述神头泉流量变化规律的数学模型。以1985年为界，神头泉的流量变化过程可分为两个阶段，GM（1，1）模型与灰色预测校正模型则分别用于对这两个阶段的流量变化特征进行刻画。神头泉2000－2004年的流量预测值表明，在神头泉域保证90年代中期的高降水量和朔州市各地下水用户对泉域内的地下水不进行超采的基础上，神头泉的流量在未来的一段时间内会维持1993年以来的增长趋势。     

非常规综合物化探油气预测研究

非常规综合物化探方法油气预测研究中存在的主要问题为：缺乏系统与综合的基础性理论研究，异常形成的机理还不十分清楚，在参数的优化组合及异常的求取上尚有诸多不足。针对后一种情况，选择松辽盆地东岭构造作为实验区进行了有益的探索。选取低能吸附烃、放射性测氡及土壤热释光三类参数进行了优化组合，分别计算了综合指标MAE与MAC及组合熵，然后对各值采用泛克里格法求取异常，取得了良好的效果。下一步研究应从异常形成的机理入手，建立三维非常规综合物化探油气预测模式，以提高油气预测成功率。     

Labour markets in transition. The experiences of women in two border regions of East Germany

The political turning point in the former GDR and the transformation processes that have been observed since then have significantly affected economic and social structures in the new Federal States. Gender roles, however, were subjected to even more dramatic changes. Whilst many women experienced the employment policies of the GDR era as beneficial, social researchers often designate them as the losers of unification nowadays. This is largely because the abundance of State support measures for employed women and mothers has been drastically reduced and women as a group have been hit hardest by the crisis on the East German labour market. Using two cases (Mecklenburg-Westpommerania and Thuringia), this paper aims to illustrate the impact of the transformation process on the everyday (working) lives of women. We are particularly concerned with a comparative analysis of how women experience and deal with regional disparities in East Germany.

Drought in Bulgaria and atmospheric synoptic conditions over Europe

Drought in Bulgaria is analyzed from the multiple viewpoints of statistical occurrence, spatial patterns, and synoptic conditions. A new index of drought, the SD (spatial-dryness) index, characterizes drought by both intensity and spatial extent. The occurrence of the SD index is analyzed using global gridded data sets. Examination of transitional probabilities of multiple months and years with drought occurrence suggests persistence is sufficiently frequent to be important for climate-related environmental planning. Finally, it is shown that specific seasonal synoptic patterns are associated with wet and dry conditions in Bulgaria.
