An essay on the interactions between climate and society     

Michael H  GLANTZ  Qian YE 《Frontiers of Earth Science》2008,2(3):356-363

There has been increasing concern about the lack of involvement by social scientists and humanists in a global change program, although many social scientists are already directly involved in various aspects of research on environmental change, and their research interests are clearly central to a global change research agenda. Based on a historical review, the role of social science disciplines as well as social science institutes in an emerging multidecadal global change program is discussed. Both “plan of action” and “plan of inaction” are suggested to avoid potential pitfalls due to the rush development of a social science program into the existing global climate change problem.  相似文献   

Climate changing characteristics of Zhangye City in Heihe River basin during 1968–2005     

Mingji Li  Yuxia Ma  Peiji Shi 《Frontiers of Earth Science》2008,2(2):243-248

At present, researches on climate change of the Heihe River basin mainly focus on the relationship between basin climate change and regional water resources, regional desertification and dynamic climatic seasons of sandstorm, but less on climate change of oasis region, where there are more intense and frequent human activities. Based on data of precipitation, temperature, strong wind and dust events frequencies obtained from the six meteorological stations of Zhangye region in Heihe River basin, the features of climate change during 1968–2005 were carefully studied. Results show that the regional temperature rise rate exceeded the average level of China. The annual precipitation changed a little, but the precipitation had a slowly increasing trend in spring and winter. Frequencies of strong wind and sandstorm days show obviously descending trends, which had a close correlation with the regional temperature rise and the precipitation increase in spring and winter. Meanwhile, further human economic activities and exploitations to the oasis in the inland valley of arid regions also affected the climate change of this region, which has a sensitive and fragile eco-environment. __________ Translated from Journal of Desert Research, 2007, 27(6): 1048–1054 [译自: 中国沙漠]  相似文献   

CSU－RAMS模式在区域气侯模拟中的应用   总被引：1，自引：0，他引：1  

万齐林  施永年 《热带气象学报》1996,(2)

将ＣＳＵ－ＲＡＭＳ（中尺度）数值模式改造成“区域气候数值模式”以及进行区域气候数值模拟的试验研究。说明将有限区域中尺度数值模式与ＧＣＭ模式嵌套应用到区域气候数值模拟研究上能够取得有意义的结果。它能在一定程度上改善ＧＣＭ模式的不足。可以更为细致地描述大气环流的变化特征,是了解区域气候变化的有效方法之一。  相似文献   

Influence of dimethylsulfide produced by marine algae on the global climate     

林荣根  刘新威 《中国海洋湖沼学报》1996,14(1):47-55

DMS (dimethylsulfide), a breakdown product of cellular solutes of many species of macroalgae andphytoplankton plays an important role in regulating global climate and counteracting partly the "greenhouse" effect.In this paper, the advance and prospects of DMS study are reviewed and discussed with respectto DMS sample storage, measurement and importance in regulating global climate and the acidity ofrain and aerosol.  相似文献   

辽宁避暑旅游气候适宜度评价     

侯亚红  息涛  明惠青  赵淼  关健华 《气象科技》2021,49(6):960-967

利用辽宁省59个国家气象站2008—2017年6—8月逐时地面观测资料，综合考虑夏季气候舒适度和高影响天气对避暑旅游的不利影响，确定辽宁避暑旅游气候适宜度评价方法，分析了辽宁避暑旅游适宜度时空分布，为公众及旅游相关部门了解当地避暑旅游气候资源提供参考。研究表明：①辽宁避暑旅游适宜度由西北到东南逐渐增强， 59个地市（县）中，很适宜避暑的有14个，适宜避暑的有22个，较适宜避暑的有16个。②夏季辽宁大部避暑旅游气候舒适度较好，辽东和辽南气候舒适度优于辽宁中部和西部。辽宁东部的本溪和沿海的丹东、大连、葫芦岛和锦州南部气候舒适度等级最高，避暑气候条件更好。③辽宁夏季暴雨高风险区在东南部的宽甸、丹东和凤城一带。高温高风险区在朝阳大部和锦州西部。大风高风险区在铁岭北部、彰武、锦州、营口和长海。雷暴高风险区在铁岭、抚顺东部、朝阳西部和庄河一带。④6月、8月是辽宁适合避暑旅游的月份，尤其是 6月，避暑旅游适宜度最高，适宜面积最大。8月份次之， 7月避暑旅游适宜度较差。  相似文献   

未来气候变化对云南柠檬气候适宜性的影响     

范丹华  杨弘伟  邵晨扬  王鹏云  朱勇 《气象科技》2021,49(6):968-974

气候变化影响柠檬生长、产量和品质，本文利用云南省125个国家气象站1981—2018年,月平均气温、月平均降水量、月日照时数，进行基准年代下云南柠檬气候适宜性分区；采用RCP2.6、RCP4.5、RCP8.5气候情景模式，研究2021—2030年、2031—2040年、2041—2050年云南柠檬气候适宜区的变化，探讨未来气候变化背景下，云南柠檬气候适宜性变化，以期对柠檬产业布局、规划、引种提供科学的指导。结果表明：21世纪中叶，RCP2.6情景下柠檬最适宜种植区增加了3成左右，RCP4.5情景下柠檬最适宜种植区增加了5成左右，RCP8.5情景下柠檬最适宜种植区增加了9成左右。但由于受降水因子的限制，中度适宜区到2041—2050年开始缩减，总的可适宜种植区（高度适宜区+中度适宜区）基本趋于稳定，这将给柠檬在云南的种植发展提供广阔空间。  相似文献   

碳中和目标下关键矿产在清洁能源转型中的作用、供需分析及其建议          下载免费PDF全文

王欢  马冰  贾凌霄  于洋  胡嘉修  王为 《中国地质》2021,48(6):1720-1733

在"碳中和"目标的驱动下，全球能源系统向清洁化、低碳化甚至无碳化发展已是大势所趋。针对向清洁能源转型的需求，采用了统计对比、分类汇总、综合分析等方法，分析研究了关键矿产在电池、电网、低碳发电和氢能等行业中的作用和需求。结合当前关键矿产产量的地理集中度高、项目开发周期长、资源质量下降等矿产供应和投资计划不能满足清洁能源转型的需求等问题，提出确保关键矿产多样性供应，推动价值链各环节的技术创新，扩大回收利用，增强供应链弹性和市场透明度，将更高的环境、社会和治理标准纳入主流程及加强生产者和消费者之间的国际合作等建议。  相似文献   

Global climatic change – the latest scientific understanding     

Bruce A. Callander 《GeoJournal》1997,42(1):55-63

IPCCs statement in its 1995 report (IPCC 1996) that a human influence was discernible in global climate has been widely quoted but often misunderstood. The character of the evidence underpinning this detection statement is explained so that its strengths and weaknesses can be better understood and the subtleties of its message better appreciated. To demonstrate the close linkage between the government-approved summary and the underlying chapters of the IPCC report the detailed evolution of the detection statement from first draft through to the form finally approved by the IPCC is described.  相似文献
