Changes in the Extremes of the Climate Simulated by CCC GCM2 under CO2 Doubling
Publisher: American Meteorological Society
Abstract: Changes due to CO2 doubling in the extremes of the surface climate as simulated by the second-generation circulation model of the Canadian Centre for Climate Modelling and Analysis are studied in two 20-yr equilibrium ...
On the ROC Score of Probability Forecasts
Publisher: American Meteorological Society
Abstract: The relative operating characteristic (ROC) is a measure of the quality of probability forecasts that relates the hit rate to the corresponding false-alarm rate. This paper examines some aspects of the ROC curve for ...
Improved Seasonal Probability Forecasts
Publisher: American Meteorological Society
Abstract: A simple statistical model of seasonal variability is used to explore the properties of probability forecasts and their accuracy measures. Two methods of estimating probabilistic information from an ensemble of deterministic ...
Estimating Extremes in Transient Climate Change Simulations
Publisher: American Meteorological Society
Abstract: Changes in temperature and precipitation extremes are examined in transient climate change simulations performed with the second-generation coupled global climate model of the Canadian Centre for Climate Modelling and ...
Climate Predictions with Multimodel Ensembles
Publisher: American Meteorological Society
Abstract: Several methods of combining individual forecasts from a group of climate models to produce an ensemble forecast are considered. These methods are applied to an ensemble of 500-hPa geopotential height forecasts derived ...
Changes in the Extremes in an Ensemble of Transient Climate Simulations with a Coupled Atmosphere–Ocean GCM
Publisher: American Meteorological Society
Abstract: The extremes of surface temperature, precipitation, and wind speed and their changes under projected changes in radiative forcing are examined in an ensemble of three transient climate change simulations for the years ...
Increasing Trend of Synoptic Activity and Its Relationship with Extreme Rain Events over Central India
Publisher: American Meteorological Society
Abstract: The nature of the increasing frequency of extreme rainfall events (ERE) in central India is investigated by relating their occurrence to synoptic activity. Using a long record of the paths and intensities of monsoon synoptic ...
Representation of Snow in the Canadian Seasonal to Interannual Prediction System. Part II: Potential Predictability and Hindcast Skill
Publisher: American Meteorological Society
Abstract: his paper examines potential predictability (PP) and actual skill for snow water equivalent (SWE) in the Canadian Seasonal to Interannual Prediction System (CanSIPS). A significant PP is found for SWE, with potentially ...
Intercomparison of Near-Surface Temperature and Precipitation Extremes in AMIP-2 Simulations, Reanalyses, and Observations
Publisher: American Meteorological Society
Abstract: The extremes of near-surface temperature and 24-h and 5-day mean precipitation rates are examined in simulations performed with atmospheric general circulation models (AGCMs) participating in the second phase of the ...
Detectability of Anthropogenic Changes in Annual Temperature and Precipitation Extremes
Publisher: American Meteorological Society
Abstract: This paper discusses a study of temperature and precipitation indices that may be suitable for the early detection of anthropogenic change in climatic extremes. Anthropogenic changes in daily minimum and maximum temperature ...
