CLIMATOLOGICAL CHARACTERISTICS FOR THE ONSET OF ASIAN SUMMER MONSOON AS REVEALED BY HIRS-Tb12 AND DROUGHT AND FLOODS IN EASTERN CHINA

As shown in comparison and study of the HIRS-Tb12 data and conventional data, temperature, humidity and vertical motion are structured differently in the Southern and Northern Hemispheres, which are well depicted with the HIRS-Tb12 data. When high pressures rapidly decrease over the regions of South China Sea and Arabian Sea with the HIRS-Tb12 less than 200 W/m2, monsoons will set off in the South China Sea, Arabian Sea and Bay of Bengal, respectively. From a year of significant drought to one of significant floods, the trend of evolution is significantly different in the downdraft areas of the subtropical highs between the two hemispheres.

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. This revised version was published online in July 2006 with corrections to the Cover Date.     

Documentary and Geological Records of Tsunamis in the Aegean Sea Region of Greece and their Potential Value to Risk Assessment and Disaster Management

Understanding the nature and impacts of tsunamis within the Aegean Sea region ofGreece is of importance to both the academic community and those organisationsconcerned with tsunami disaster management. In order to determine hazard and riskand consequently pre-plan mitigative strategies, it is necessary to analyse historical(documentary) and geological records of former tsunami events. Therefore, firstlythis paper provides a summary of the written sources of information on Aegeantsunamis paying particular attention to published catalogues. From the availabledata, it is noted that a large number of events have been reported during the last3500 years. Secondly, the paper provides a review of the published on-shore(terrestrial) geological records of tsunamis within the region. From this analysisit is seen that little geological evidence has been identified for the large numberof tsunamis reported in the catalogues. Thirdly, the paper considers the reliabilityof the written and geological records and how problems of accuracy, coverage,extent and reliability, may have potential implications for the estimation of hazardand risk. The paper concludes by making recommendations for disaster managers,geologists and historians to work closely together.     

四川省房屋建筑易损性研究

研究房屋建筑易损性特征是防震减灾工作必不可少的环节之一，本文通过对多年工作的系统总结，得出四川省不同地区的房屋建筑易损性矩阵，全省房屋建筑抗震性能总体水平不高，这是造成地震灾害加重的主要原因之一，随着经济发展实力的提高，适当提高全省房屋建筑抗震设防水平可大大减轻特别是中强地震所造成的经济损失。     

城市地区抗御地震灾害风险评估项目综述

城市地区抗御地震灾害风险评估项目系联合国在上世纪末为减轻地震灾害所实施的规模宏大，影响甚远的国际性研究项目，其宗旨是为了提高社会公众防灾意识，有效地减轻城市地区的地震灾害。这一历时2年的项目在有限的经费支持下，取得了令人瞩目的成绩。结合自贡市开展这个项目的实践。综合介绍和总结了该项目的情况及经验。     

城市震害高危害小区的研究和GIS的实现技术

论述了在城市地震灾害中如何考虑诸方面因素来评价城市的灾害轻重分布情况。中建立坑危害小区分析模型，设想将城市划分等面积网格，给每个单元网格赋予灾害指数，以确定城市中受灾较为严重的区域，为求灾指挥提供决策信息。同时，将高危害小区的模型研究结果转化为计算机技术可以实现的GIS模型。该研究结果已应用于泰安市防震减灾示范研究项目中。     

企业地震预警系统应用研究

在充分调研国外地震预警系统现状的基础上，进行了地震预警系统的研究，研制了相应的数据分析软件。采用数字化观测技术、GIS技术等高新技术，在中国石油天然气股份有限公司大连分公司建立了地震预警试验系统，并将该地震预警系统与地震应急系统相连，为今后开展类似工作积累了经验。     

吉林省发展绿色食品的农业生态环境优势分析

发展绿色食品生产是吉林省实施“生态省”建设工程的主导产业之一，本文按照绿色食品产地环境质量标准要求，客观评价了吉林省发展绿色食品的产地环境条件，得出吉林省具有发展绿色食品生产的显著农业生态环境优势。基于吉林省良好的农业生态环境质量，结合区域自然条件和资源优势，将全省分为东部山区、中部松辽平原区、西部松嫩平原区和大、中城市郊区四种区域类型，并分别提出了其发展绿色食品生产的宏观策略。
