RISDevelopment of an Antarctic Regional Climate System Model. Part I: Sea Ice and Large-Scale Circulation
Publisher: American Meteorological Society
Abstract: A coupled atmosphere?ice regional model previously used for simulations in the Arctic has been implemented in the Antarctic. Three 14-month simulations were performed for 1988?89, with different oceanic specifications. The ...
Development of an Antarctic Regional Climate System Model. Part II: Station Validation and Surface Energy Balance
Publisher: American Meteorological Society
Abstract: In this, the second part of the analysis of an Antarctic regional climate system model, the model results and analyses are compared to a series of observational data from automated weather stations at a number of Antarctic ...
Changing Seasonal Predictability of Arctic Summer Sea Ice Area in a Warming Climate
Publisher: American Meteorological Society
Abstract: AbstractWe use a large ensemble set of simulations and initialized model forecasts to assess changes in the initial-value seasonal predictability of summer Arctic sea ice area from the late-twentieth to the mid-twenty-first ...
An Origami-Based Medical Support System to Mitigate Flexible Shaft Buckling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the development of an origami-inspired support system (the OriGuide) that enables the insertion of flexible instruments using medical robots. Varying parameters of a triangulated cylindrical origami ...
Twenty-First-Century Arctic Climate Change in CCSM4
Publisher: American Meteorological Society
Abstract: he authors summarize the twenty-first-century Arctic climate simulated by NCAR?s Community Climate System Model, version 4 (CCSM4). Under a strong radiative forcing scenario, the model simulates a much warmer, wetter, ...
Improved Sea Ice Shortwave Radiation Physics in CCSM4: The Impact of Melt Ponds and Aerosols on Arctic Sea Ice
Publisher: American Meteorological Society
Abstract: he Community Climate System Model, version 4 has revisions across all components. For sea ice, the most notable improvements are the incorporation of a new shortwave radiative transfer scheme and the capabilities that this ...
The Low-Resolution CCSM4
Publisher: American Meteorological Society
Abstract: he low-resolution version of the Community Climate System Model, version 4 (CCSM4) is a computationally efficient alternative to the intermediate and standard resolution versions of this fully coupled climate system model. ...
True to Milankovitch: Glacial Inception in the New Community Climate System Model
Publisher: American Meteorological Society
Abstract: he equilibrium solution of a fully coupled general circulation model with present-day orbital forcing is compared to the solution of the same model with the orbital forcing from 115 000 years ago. The difference in snow ...
The Influence of Local Feedbacks and Northward Heat Transport on the Equilibrium Arctic Climate Response to Increased Greenhouse Gas Forcing
Publisher: American Meteorological Society
Abstract: his study uses coupled climate model experiments to identify the influence of atmospheric physics [Community Atmosphere Model, versions 4 and 5 (CAM4; CAM5)] and ocean model complexity (slab ocean, full-depth ocean) on the ...
Late-Twentieth-Century Simulation of Arctic Sea Ice and Ocean Properties in the CCSM4
Publisher: American Meteorological Society
Abstract: o establish how well the new Community Climate System Model, version 4 (CCSM4) simulates the properties of the Arctic sea ice and ocean, results from six CCSM4 twentieth-century ensemble simulations are compared here with ...
