DESCRIPTION

关于极端天气气候指数定义 的一些思考. 翟盘茂. 问 题. 为什么要定义极端事件指数? 如何定义极端事件? 如何衡量气候是否更加极端化了? 极端事件与气象灾害有什么差异? 极端事件指数研究的未来思考?. 为什么定义极端指数?. 1 、气候变化研究需要. 气候变化信号检测 极端事件变化成因研究 与模式结果比较 预估. 2 、事件监测、预警与影响(灾害)评估. 如何定义极端事件?. 当某地的气候状态严重偏离其平均态时,就 可以认为是不易发生的事件。在统计意义上,不容易发生的(值)事件就可以称为极端(值)事件。. 按照当地的某种观测资料的 - PowerPoint PPT Presentation

  • Extreme Event

    Extreme event is generally defined as the occurrence of a value of a weather or climate variable above (or below) a threshold value near the upper (or lower) ends (tails) of the range of observed values of the variable . (SREX)

  • Tmax35C50mm

  • Absolute thresholds can also be used to identify extreme events (e.g., specific critical temperatures for health impacts).

  • Temperature Extreme Indices

  • Tmax 95th percentile Tmin95th percentile

  • Temperature Extreme Indices

  • abc

  • Changes in extremes of temperature are also consistent with warming of the climate200(X)

  • 40mm10mm

  • Definitions of thresholds vary, but values with less than a 10%, 5% or 1% or even lower chance of occurrence during a specified reference period (generally 1961-1990) are often used.

  • Joint CCl/CLIVAR/JCOMM Expert Team (ET) on Climate Change Detection and Indices (ETCCDI)

    27 Core indicesFor moderate extremes

  • many more for snow, drought, etc. return values for more rare extremes (based on GEV analysis for consecutive 20yr periods) factsheets for significant weather events from the past (impacting energy, health, disasters, water, etc.)

  • POT peaks-over-threshold is used to represent the behaviour of exceedances above a high threshold and the threshold crossing process. Under suitable conditions, and using a high enough threshold, extremes identified in this way will have a generalized Pareto, or GP, distribution (see, for example, Smith, 2002).

    block maximum method. Statistical theory indicates that the Generalized Extreme Value, or GEV, distribution is appropriate for the block maxima when blocks are sufficiently large. In its general form, the GEV distribution has three parameters: location, scale, and shape.
