正The dramatic changes in the Arctic climate system during recent decades are one of the most prominent features of global climate change.Two most striking and fundamental characteristics are the amplified near-surface warming at a rate twice the global average since the mid 20th century(e.g.,Blunden and Arndt,2012;Huang et al.,2017),and the rapid  相似文献

<正>The Antarctic, including the continent of Antarctica and the Southern Ocean, is a critically important part of the Earth system. Research in Antarctic meteorology and climate has always been a challenging endeavor. Studying and predicting weather patterns in the Antarctic are important for understanding their role in local-to-global processes and facilitating field  相似文献

Tropical cyclones(TCs) are one of the most destructive natural phenomena on Earth in terms of human-life and economic losses. It is currently a matter of prodigious public and scientific interest how TC activity has changed and will change in a warming climate. This special issue focuses on a challenging subject raised in the Intergovernmental Panel on Climate Change(IPCC) report and numerous research papers.  相似文献

<正>The Arctic climate system has changed rapidly during recent decades with a two-four times faster warming rate than the global average subject to the uncertainties of analysis datasets and approaches. These changes have apparently resulted in broader and sizeable impacts within the Arctic, in the low/mid-latitudes, and globally. The importance of these changes and impacts makes the Arctic stand out within the global climate systems,  相似文献

天气和气候之间的桥梁——分数阶导数   总被引:2,自引:1,他引:2  
天气和气候虽然遵从流体力学规律,但是却显示出随机性,研究天气和气候之间的关系必须引入分数阶的导数和积分,从物理上讲不外乎说明天气和气候的随机程度是不相同的。为此提出气候的q(0≤q≤1)阶微商是天气,扩展了Hasselmann的结果。实际资料分析表明,气候距平具有长程相关,比天气有更好的记忆性。气候距平的概率密度分布函数有较长的尾巴,较长的尾巴反映了极值气候所发生的频率。  相似文献

Climate change will injure vulnerable communities. In response, coordinated global action has emerged to mitigate climate change, to gauge and map climate-related risks, and to plan for adaptation, which in turn has opened new avenues of funding, power, knowledge and opportunity. The identification of climate risks, analysis and diffusion of ‘impact’ scenarios, incorporation of carbon into economic regimes, and interventions to enhance adaptive capacity will necessarily be experienced differently by different groups. As climate-related crises produce winners and losers, so may discourses and plans made to avert such crises. In the process both the bio-physical events and the social responses shape and reshape social stratification and the distribution of risk. They produce new inequalities and needs for new kinds of responses to guard against injustice. From the emergence of desalination water projects and contested water access, to relocation planning in the Arctic and the South Pacific due to sea-level rise, to increasingly centralized forest management; mitigation and adaptation responses and interventions create their own critical outcomes. This essay and the articles in this special issue examine some new opportunities and risks associated with climate-change discourses and interventions. This special issue shows that vulnerable communities may be at risk of material injury following climate change or climate change intervention; and, be further insulted and injured by lack of representation and recognition, and by misrecognition as simplified, stereotyped victims in local, national and international climate conversations. Using a mixture of theoretical insight and case study research, this collection of articles explores the injuries of climate change as it applies to both direct physical stress scenarios and exposure to adaptation and mitigation policies and planning, as well as the discursive insults of being discounted, stereotyped, or ignored.  相似文献

<正>A mesoscale convective system (MCS) is an organized cluster of thunderstorms known to be the most important convective mode in causing disastrous high-impact weather, such as heavy rainfall, hail, damaging winds, and tornadoes. The small spatial scale and fast temporal evolution of MCSs make their observation and prediction very challenging. East Asia is home to the world’s most prominent monsoon, setting the stage for various severe convective weather events. MCSs and their associated ...  相似文献

极端天气和气候事件的变化   总被引:4,自引:0,他引:4       下载免费PDF全文
自1950年以来的观测证据表明,有些极端天气和气候事件已经发生了变化。全球尺度上,人为影响可能已经导致极端日最低和最高温度升高;由于平均海平面上升,人类活动可能已对沿海极端高水位事件的增加产生了影响;具有中等信度的是,人为影响已导致全球强降水增加;由于热带气旋历史记录的不确定性、缺乏对热带气旋与气候变化之间关联的物理机制的完整认识及热带气旋自然变率的程度,将可检测到的热带气旋活动变化归因于人为影响仅具有低信度。将单一的极端事件变化归因于人为气候变化具有挑战性。对极端事件变化预估的信度取决于事件的类型、区域和季节、观测资料的数量和质量、基本物理过程的认知水平及模式对其模拟的可靠性。  相似文献
