RISRepresenting Extremes in a Daily Gridded Precipitation Analysis over the United States: Impacts of Station Density, Resolution, and Gridding Methods
Publisher: American Meteorological Society
Abstract: his study focuses on errors in extreme precipitation in gridded station products incurred during the upscaling of station measurements to a grid, referred to as representativeness errors. Gridded precipitation station ...
Patterns of Sea Ice Retreat in the Transition to a Seasonally Ice-Free Arctic
Publisher: American Meteorological Society
Abstract: he patterns of sea ice retreat in the Arctic Ocean are investigated using two global climate models (GCMs) that have profound differences in their large-scale mean winter atmospheric circulation and sea ice drift patterns. ...
A Regional Seasonal Forecast Model of Arctic Minimum Sea Ice Extent: Reflected Solar Radiation versus Late Winter Coastal Divergence
Publisher: American Meteorological Society
The Impact of Stratospheric Circulation Extremes on Minimum Arctic Sea Ice Extent
Publisher: American Meteorological Society
Abstract: AbstractGiven the rapidly changing Arctic climate, there is an urgent need for improved seasonal predictions of Arctic sea ice. Yet, Arctic sea ice prediction is inherently complex. Among other factors, wintertime atmospheric ...
The Influence of Cloud and Surface Properties on the Arctic Ocean Shortwave Radiation Budget in Coupled Models
Publisher: American Meteorological Society
Abstract: The impact of Arctic sea ice concentrations, surface albedo, cloud fraction, and cloud ice and liquid water paths on the surface shortwave (SW) radiation budget is analyzed in the twentieth-century simulations of three ...
How Well Are the Distribution and Extreme Values of Daily Precipitation over North America Represented in the Community Climate System Model? A Comparison to Reanalysis, Satellite, and Gridded Station Data
Publisher: American Meteorological Society
Abstract: n intercomparison of the distribution and extreme values of daily precipitation between the National Center for Atmospheric Research Community Climate System Model, version 4 (CCSM4) and several observational/reanalysis ...
The Granular Sea Ice Model in Spherical Coordinates and Its Application to a Global Climate Model
Publisher: American Meteorological Society
Abstract: The granular sea ice model (GRAN) from Tremblay and Mysak is converted from Cartesian to spherical coordinates. In this conversion, the metric terms in the divergence of the deviatoric stress and in the strain rates are ...
