      Risbey, James S.; Kandlikar, Milind (American Meteorological Society, 2002)
      The problem of detection of climate change and attribution of causes of change has been formalized as a series of discrete probability judgements in an expert elicitation protocol. Here results are presented from the ...
    • Recent Changes in Frost Days and the Frost-Free Season in the United States 

      Easterling, David R. (American Meteorological Society, 2002)
      One of the signals expected with greenhouse warming is a change in what are now considered extreme temperatures. In this paper one type of extreme is examined for the 1948-99 period, that is, a change in the number of days ...
    • The Weather Risk Management Industry's Climate Forecast and Data Needs: A Workshop Report

      The National Oceanic and Atmospheric Administration (NOAA), the Risk Prediction Initiative, and the Weather Risk Management Association jointly sponsored a workshop that examined a variety of issues related to climate ...
    • The Quantification of Drought: An Evaluation of Drought Indices 

      Keyantash, John; Dracup, John A. (American Meteorological Society, 2002)
      Indices for objectively quantifying the severity of meteorological, agricultural, and hydrological forms of drought are discussed. Indices for each drought form are judged according to six weighted evaluation criteria: ...

    • A Review of Twentieth-Century Drought Indices Used in the United States 

      Heim, Richard R. (American Meteorological Society, 2002)
      The monitoring and analysis of drought have long suffered from the lack of an adequate definition of the phenomenon. As a result, drought indices have slowly evolved during the last two centuries from simplistic approaches ...
