RISStatistical Considerations for Climate Experiments. Part II: Multivariate Tests
Publisher: American Meteorological Society
Abstract: Several multivariate tests for differences of the mean which are based upon resampling schemes are examined in a series of Monte Carlo experiments. We examine the power of these tests under two sets of experimental situations: ...
A Potential Predictability Study Conducted with an Atmospheric General Circulation Model
Publisher: American Meteorological Society
Abstract: This paper describes a potential predictability study on the results of a 20.5 year simulation conducted with the Canadian Climate Centre (CCC) General Circulation Model (GCM). The CCC GCM is an atmosphere GCM with surface ...
The Interpretation and Estimation of Effective Sample Size
Publisher: American Meteorological Society
Abstract: Statistical and dynamical relationships between observed values of a geophysical system or model effectively reduce the number of independent data. This reduction is expressible in terms of the covariance structure of the ...
Statistical Considerations for Climate Experiments. Part I: Scalar Tests
Publisher: American Meteorological Society
Abstract: Statistical tests used in model intercomparisons or model/climate comparisons may be either ?scalar? or ?multivariate? tests. The former are employed when testing a hypothesis about a single variable observed at a single ...
A Comparison of Climates Simulated by a General Circulation Model when Run in the Annual Cycle and Perpetual Modes
Publisher: American Meteorological Society
Abstract: A comparison is made between the climate simulated by the Canadian Climate Centre (CCC) General Circulation Model when run its usual ?annual cycle?mode, in which the solar declination angle varies annually, and the climate ...
The Enhanced PNA-Like Climate Response to Pacific Interannual and Decadal Variability
Publisher: American Meteorological Society
Abstract: This study provides further evidence of the impacts of tropical Pacific interannual [El Niño?Southern Oscillation (ENSO)] and Northern Pacific decadal?interdecadal [North Pacific index (NPI)] variability on the Pacific?North ...
An Evaluation of Block-Maximum-Based Estimation of Very Long Return Period Precipitation Extremes with a Large Ensemble Climate Simulation
Publisher: American Meteorological Society
Abstract: The recurring devastation caused by extreme events underscores the need for reliable estimates of their intensity and frequency. Operational frequency and intensity estimates are very often obtained from generalized extreme ...
Probable Maximum Precipitation: Its Estimation and Uncertainty Quantification Using Bivariate Extreme Value Analysis
Publisher: American Meteorological Society
Abstract: AbstractProbable maximum precipitation (PMP) is the key parameter used to estimate the probable maximum flood (PMF), both of which are important for dam safety and civil engineering purposes. The usual operational procedure ...
Attribution of Arctic Sea Ice Decline from 1953 to 2012 to Influences from Natural, Greenhouse Gas, and Anthropogenic Aerosol Forcing
Publisher: American Meteorological Society
Abstract: AbstractThe paper presents results from a climate change detection and attribution study on the decline of Arctic sea ice extent in September for the 1953?2012 period. For this period three independently derived observational ...
PDRMIP: A Precipitation Driver and Response Model Intercomparison Project, Protocol and preliminary results
Publisher: American Meteorological Society
Abstract: s the global temperature increases with changing climate, precipitation rates and patterns are affected through a wide range of physical mechanisms. The globally averaged intensity of extreme precipitation also changes ...
