中国夏季降水异常空间模与副热带高压的关系

本文用1959～1994年6、7、8月全国范围47个5°×5°经纬度网格降水资料分析了夏季降水异常空间模的月际差异，并在此基础上用西太平洋副高指数及青藏高原指数#FKB#FS分析降水异常空间模与环流的关系，为检验环流指数与降水相关场的整体信度，还对8月份降水资料进行了Monte-Carlo检验。结果表明，夏季总降水异常的空间模在每一月份中并非表现得同样清楚，江淮流域与河套及华南的反相关在8月份表现得最清楚。而青藏高原中东部南北两侧的负相关在6月及8月很清楚，7月份次之。8月份西太平洋副高北界异常对江淮流域与河套及华南地区降水异常反相关的产生有很大作用。副高稳定偏北时，河套、华南易涝，江淮易旱。反之亦然。青藏高原指数#FKB#FS与逐月降水的相关分析表明，青藏高原上高压及低涡活动对高原中东部南北两侧负相关的产生有一定作用。当高压活动偏多时，北侧易旱、南侧易涝。并且6月及8月的作用较大，7月较小。另外，8月份副高活动对这一降水异常空间模的产生也有一定影响。

祁连山地区1310年以来湿润指数及其年际变幅的变化与突变分析

本文通过用树木年轮资料重建的祁连山地区5～7月份1310年以来的湿润指数序列，建立了一个反映该地区湿润指数年际变幅序列，对这两个序列分别进行了等级分类和干湿、强弱的时段分析，并用最大熵谱分析法对这两个序列的不同时段分别进行了周期分析。采用HK突变检验方法对这两个序列分别进行了突变分析，发现祁连山地区的湿润指数及其年际变幅存在明显的突变年份。

Assessment of hydrogeological conditions in basement aquifers of the Precambrian Oban massif, southeastern Nigeria

A combined analysis of lineament length density from radar imagery and surface resistivity data is used to assess the hydrogeological conditions in the Oban massif, Nigeria. The results show that the data guided the qualitative and quantitative estimation of some aquifer parameters. These include resistivity of the water bearing formations (280–740 ω m), thickness (5–140 m), limited hydraulic conductivity (8.53-13.18 m/day) and transmissivity (410.65–725.88 m²/day) data. In addition, the lineament length density for the area ranged between less than 0.2 to slightly more than 0.4. Site evaluation for the location of productive boreholes/wells using a groundwater potential index (GWPI) indicates that areas with a GWPI of greater than 35 are consistent with relatively high yield.     

应用灰色系统理论进行地震灾害等级划分和灾情分析比较

通过对地震时人员死亡、受伤、房屋破坏和直接经济损失４个灾害损失指标的函数转换，使得用不同的损失指标判别灾害等级的标准取得了统一．然后，应用灰色聚类方法划分地震灾害等级，并用灰色关联度排序方法对不同的灾情进行分析比较．同时还对１９６６～１９８３年我国大陆７次重要地震和１９９５年我国大陆１７次地震进行了灾害等级划分和不同灾情的分析比较．结果表明，该方法基本可定量准确地评价地震灾情

STUDY ON THE VARIATION IN THE CONFIGURATION OF SUBTROPICAL ANTICYCLONE AND ITS MECHANISM DURING SEASONAL TRANSITION-PART Ⅱ:SEASONAL TRANSITION INDICES OVER THE ASIAN MONSOON REGION

Based on the studies in Part Ⅰ (see Mao et al.2003),this paper further examines the relationship between the Asian summer monsoon onset and variation in meridional position of the warm temperature ridge with a zonal orientation in mid-upper troposphere.During the Asian monsoon bursting consequentially over the Bay of Bengal,South China Sea,and South Asia,in addition to the reversal of winds in the lower and upper troposphere and deep convection before and after the onset,the atmospheric meridional temperature gradient (MTG) in the vicinity of the ridge-surface of subtropical high (WEB defined in Part Ⅰ) exhibits a significant reversal.Since the establishment of temperature structure with higher over north than over south of the WEB in the mid-upper troposphere (200-500 hPa) characterizes the collective essential that the Asian summer monsoon bursts over different areas,the MTG in mid-upper troposphere,based on the thermodynamics associated with the seasonal transition,should be a reasonable index to measure the Asian monsoon onset.The definition for onset date is proposed,and the time series of onset date for different sections are determined.As compared with the onset dates determined by other indices such as 850-hPa zonal wind and OLR.correlation analyses indicate that the 850-hPa zonal wind is only regional index,but the MTG index is applicable universally to the Asian monsoon regime.     

AN APPARENT TEMPERATURE MODEL BASED ON THERMAL EQUILIBRIUM

In this paper,a comprehensive analysis and review of the advances in the research of human body comfort degree is made.Based on the studies of human thermal equilibrium theories contributed by previous researchers,different apparent temperature models corresponding to different environments are set up in accordance with the current situation and the characteristics of metabolism in different groups of people in China.After case studies and comparison with present dominant human body comfort degree statistical models,it is proved that the apparent temperature models have high rationality and wide adaptability.Furthermore,the comfort scaling standard according to apparent temperature is suggested,which is suitable for the middle latitude regions in China.
