The connection between El Niño/Southern Oscillation (ENSO) events and precipitation and temperature variability worldwide is increasingly well understood. ENSO has been linked to droughts and flooding in some regions. This paper uses the disaster history database of the U.S. Agency for International Development's Office of U.S. Foreign Disaster Assistance to examine the link between ENSO events and droughts or floods of sufficient magnitude to trigger international disasters. Worldwide, disasters triggered by droughts are twice as frequent during year two of ENSO warm events than during other years. No such relationship is apparent in the case of flood disasters. Drought disasters occur during year two of ENSO warm events significantly more frequently than in other years in Southern Africa and Southeast Asia. No regional pattern emerges from a comparable analysis of flood disasters. Those places likely to be affected by ENSO-triggered droughts can take proactive measures to mitigate the impacts. 相似文献

The Symposium was sponsored by the Association of Schools of Public Health, the U.S. Public Health Service and the Centers for Disease Control (CDC), the World Health Organization (WHO), the South Pacific Commission, and the East–West Center of the University of Hawaii. The full proceedings are being prepared for publication. The Symposium was supported in part by: The Pan American Health Organization and The Amoco Foundation. 相似文献

Accidents and sudden illness constitutes a major public health problem in many countries. Emergency medicine had developed as a vigorous new specialty in the U.S. and has fully integrated itself within the American medical and hospital system to provide improved emergency medical care. Emergency medicine plays a central role in disaster medical services, planning, and management and is the only specialty in American civilian medicine that includes disaster medicine as a primary field within its domain. Now that the basic framework of emergency medicine has been established, the American College of Emergency Physicians is implementing a nationwide training program on disaster planning and management for emergency physicians. 相似文献

现有参数化台风风场模型通常采用单一地表粗糙度假设,忽略地形和土地覆盖的影响,使得参数化台风风场模型不能真实反映台风风场。本文基于GTOPO30(Global Topographic Data of 30 arc seconds)全球数字高程数据和USGS(U.S.Geological Survey)全球土地覆盖数据,将地形地貌效应等效为地表粗糙长度,建立了受西北太平洋台风影响的东亚地区的地表粗糙长度空间分布;并对比验证了3个典型地貌的地表粗糙长度。然后,对参数化台风风场模型进行了适当修正,使其能耦合地形起伏对风场产生的抬升和沉降作用。以WRF(Weather Research and Forecasting)模式的模拟结果为基准,采用3个历史台风案例,考察了地形地貌对参数化台风风场模拟的影响。对比结果表明,考虑地形地貌效应可以显著提升参数化台风风场模型对台风空间结构的模拟能力。考虑地形地貌影响的参数化台风风场模型的模拟结果与实测结果吻合较好。 相似文献

In 2011, thunderstorms in the United States resulted in 550 deaths from tornadoes and more than $28 billion in property damage, according to data from the US National Oceanic and Atmospheric Administration, with the vast majority of economic losses resulting from tornadoes. This article normalizes U.S. tornado damage from 1950 to 2011, using several methods. A normalization provides an estimate of the damage that would occur if past events occurred under a common base year's societal conditions. We normalize for changes in inflation and wealth at the national level and changes in population, income and housing units at the county level. Under several methods, there has been a sharp decline in tornado damage. This decline corresponds with a decline in the reported frequency of the most intense (and thus most damaging) tornadoes since 1950. However, quantification of trends in tornado incidence is made difficult due to discontinuities in the reporting of events over time. The normalized damage results are suggestive that some part of this decline may reflect actual changes in tornado incidence, beyond changes in reporting practices. In historical context, 2011 stands out as one of the most damaging years of the past 61 years and provides an indication that maximum damage levels have the potential to increase should societal change lead to increasing exposure of wealth and property. 相似文献

应用地电阻率各向异性度S值计算公式和程序,对江苏地区4个地电台1980~1997年的地电阻率各向异性度S值进行了计算研究分析。 结果表明,S值这一新的电性参数在江苏南黄海2次6级以上地震前存在异常变化。 地电阻率各向异性度S值可以作为一种新的电性参数应用于地震综合预报研究。 在讨论中对S值的定义提出改进的公式,与同仁商榷。 相似文献

安徽地区地震活动周期表将公元288 年以来M≥4 .0 地震活动划分为与华北二至七周期相对应的六个地震周期,每周期分为与华北相似的初震段、前震段、主震段和余震段四个地震段。安徽地震周期超前于华北地震周期,每周期4 级以上地震从皖渐交界一带的皖东南地区开始活动,各阶段最大地震震中由南向北迁移。第七周期4 级以上地震活动至1979 年固镇5 级地震已结束,未来将进入第八周期初震段。近几年皖东南地区的广德县或旌德县可能发生4-3 级左右地震。 相似文献

对长江中下游 南黄海地震带地震活跃期、幕划分及其发展趋势进行了研究,对江苏及其邻区今后几年的地震大形势及重点危险区进行了判定。分析认为,长南带从1971年以来进入第二活跃期的第3幕,该幕地震活动将持续到2010年前后,最高活动水平为6.5级左右。今后几年江苏东部至南黄海海域发生5~6级或6级以上地震的可能性较大。 相似文献

In 1984 and 1985, Chad was affected by a large scale drought. In order to ensure rapid decision making for the allocation of food and because of the practical problems encountered when using the classical nutritional survey methods, a Nutritional Score System (N.S.S) was developed. This method was based on the use of social, economic and nutritional indicators and allowed comparison of nutritional status between communities. This paper discusses how the N.S.S. was developed and applied, and how it compared with the classical survey methods. 相似文献
