查询词典 climate change

Reference crop evapotranspiration (ET0) and new wetness index were both calculated and analyzed according to Penman-Monteith scheme recommended by FAO with routine meteorological data from 616 weather stations in China from 1975 to 2004. In terms of grades of wetness index from Chinese Climate Classification Criterion, China is classified into severe arid, arid, semi-arid, semi-humid and humid zones, respectively, which are compared with the demarcations from rainfall-based indices in order to reveal the similarity and difference in association with the two schemes under current global climate warming. Besides, the spatio-temporal analysis of climate wetness over the country in the past thirty years was performed.

Based on the results simulated by PRECIS (Providing Regional Climates for Impacts Studies), which is developed in the Hadley Centre for Climate Prediction and Research, changes of surface air temperature and precipitation under SRES B2 scenario in South China during 2071~2100 are analyzed. It is shown that, compared to baseline (1961~1990), surface air temperature in 2071~2100 would increase by 2~4℃, precipitation in summer would increase in the north part to 22°N, while the precipitation in winter would decrease in the whole areas of South China. The climate trend of the surface air temperature would be positive, however the climate trend of the precipitation would be negative, the occurrence frequency of extremely high temperature events and extremely heavy precipitation events would increase.

利用英国Hadley气候预测和研究中心的区域气候模式系统PRECIS，模拟分析基于政府间气候变化专门委员会 2000年发布的《排放情景特别报告》中设计的B2情景下华南区域2071~2100年的温度和降水量的可能变化，结果显示：2071~2100年均地面温度相对于气候基准时段（1961~1990年）上升约2~4℃；华南区域未来夏季降水量在22°N以北区域较气候基准时段增加，而以南区域减少；冬季降水则表现为华南区域较气候基准时段减少。2071~2100年华南区域的温度气候趋势系数为正值，年均降水气候趋势系数为负值。2071~2100年的高温事件和强降水事件的发生频率均比气候基准时段明显增加。

P in Shule River Alluvial Fan Oasis in Gansu subsidized by CNSF. Through field geological and environmental observations and sampling, quartz OSL dating, organic carbon ~(14)C dating, as well as analysis of TOC,grain size and Pollen assemblage of the samples from ten sediment profiles in front fine grain sediment zone of the Shule River Fan, the results obtained as follows:(1)The vegetation evolution history on Shule River Alluvial Fan and circumjacent since about 13 ka B.P. could be divided into 6 phases: about 12.1-13.1ka, a sparse coniferous and broadleaf trees - shrub grassland, cold and wet climate; 9.2-12.1ka, shrub grassland, temperature rising but precipitation and humidity getting down; 5.8-9.2ka, sparse forest with the most flourish shrub grassland under the optimal climate; 4.3-5.8ka, coniferous and broadleaf mixed forests -shrub grassland, temperature rising slightly and getting dry; 4.3-2.8ka, grass vegetation and climate became more dry; 2.8-2.3ka, coniferous forests -shrub grassland, precipitation and temperature getting down, but a higher relative humidity.

本文依托于&甘肃疏勒河冲积扇5万年来古天气环境与古水文演化&项目，以疏勒河冲积扇为研究对象，通过对疏勒河冲积扇扇缘细土带全新世古天气和古水文演变进行了20余个剖面的观测和取样、石英OSL和~(14)C测年、粒度组成和TOC分析以及孢粉鉴定，获得了以下成果和熟悉：(1)距今约13ka年来冲积扇和周边植被演化经历了6个阶段：约13.1～12.1ka，以针叶林为主的针阔混交林～灌丛草原，天气冷湿；12.1～9.2ka，灌丛草原，气温升高，降水量较低；9.2～5.8ka，疏林灌木草原，植被茂盛，温度和降水最佳；5.8～4.3ka，以针叶树为主的针阔混交林～灌丛草原，气温较高，降水减少；4.3～2.8ka，草原植被，天气变干；2.8～2.3ka，针叶林～灌木草原，降水减少，温度降低，相对湿度有所增加。

Abrupt climate change is one of most important manifestation of climate change, is a integrative science of physics and climatology.

A positive correlation was found between the solar activity and NO3- concentration in recent 1500 years. A long-standing issue of the nature of the solar activity during the Maunder Minimum was solved. An about 36a cycle was found in the solar activity. Low solar activity and weak geomagnetic field were responsible for the 36Cl peak at about 37ka BP. Climate change recorded in this ice core lagged insolation about 4ka during the last glacial maximum, about 1ka during the last deglaciation, and nearly 0ka during the Holocene.δ18O record also suggests that the variation in temperature on the Tibetan Plateau had some similar features to that in both Northern and Southern Hemispheres during the last deglaciation to some extent, which indicate that the tropics maybe play an important role on global climate change.

揭示出近1500a来古里雅冰芯中NO3-浓度变化可以反映太阳活动的强弱变化；回答了长期争议的并直接关系到太阳发电机理论是否正确的Maunder极小期太阳活动特征问题；发现太阳活动可能存在36a左右的周期；证实了37kaBP左右古里雅冰芯记录中宇宙成因同位素36Cl含量峰值的存在，指出这一时期的宇宙成因同位素峰值事件具有全球性，弱的太阳活动和弱的地磁场是这一事件发生的原因所在；揭示出古里雅冰芯记录到的"8.2ka BP事件"，认为这一全球性事件发生的主要原因与弱的热盐环流和弱的太阳活动有关；发现古里雅冰芯记录的末次冰盛期和末次冰消期气候变化均在一定程度上滞后于太阳辐射变化，而全新世气候变化大致与太阳辐射变化同步；发现末次冰消期高原地区气候变化不仅具有北半球气候变化的某些特征，同时还具有南半球气候变化的某些特征，这说明热带地区可能对全球气候存在重要的影响。
