RISMJO-Related SST Variations over the Tropical Eastern Pacific during Northern Hemisphere Summer
Publisher: American Meteorological Society
Abstract: The Madden?Julian oscillation (MJO) significantly modulates eastern tropical Pacific sea surface temperatures (SSTs) during Northern Hemisphere summer. Typical SST variations during an MJO life cycle are 0.4°?0.5°C. ...
The Community Climate System Model, Version 2
Publisher: American Meteorological Society
Abstract: The Community Climate System Model, version 2 (CCSM2) is briefly described. A 1000-yr control simulation of the present day climate has been completed without flux adjustments. Minor modifications were made at year 350, ...
Intraseasonal Eastern Pacific Precipitation and SST Variations in a GCM Coupled to a Slab Ocean Model
Publisher: American Meteorological Society
Abstract: Coupling the NCAR Community Climate Model version 3.6 (CCM3.6) with relaxed Arakawa?Schubert convection to a slab ocean model (SOM) improves the simulation of eastern Pacific convection during a composite June?November ...
Using the Radiative Kernel Technique to Calculate Climate Feedbacks in NCAR’s Community Atmospheric Model
Publisher: American Meteorological Society
Abstract: Climate models differ in their responses to imposed forcings, such as increased greenhouse gas concentrations, due to different climate feedback strengths. Feedbacks in NCAR?s Community Atmospheric Model (CAM) are separated ...
Earth's Global Energy Budget
Publisher: American Meteorological Society
Abstract: An update is provided on the Earth's global annual mean energy budget in the light of new observations and analyses. In 1997, Kiehl and Trenberth provided a review of past estimates and performed a number of radiative ...
Response of Climate Simulation to a New Convective Parameterization in the National Center for Atmospheric Research Community Climate Model (CCM3)
Publisher: American Meteorological Society
Abstract: This study examines the response of the climate simulation by the National Center for Atmospheric Research Community Climate Model (CCM3) to the introduction of the Zhang and McFarlane convective parameterization in the ...
Response of Climate Simulation to a New Convective Parameterization in the National Center for Atmospheric Research Community Climate Model (CCM3)
Publisher: American Meteorological Society
Abstract: This study examines the response of the climate simulation by the National Center for Atmospheric Research Community Climate Model (CCM3) to the introduction of the Zhang and McFarlane convective parameterization in the ...
On Using Global Climate Model Simulations to Assess the Accuracy of MSU Retrieval Methods for Tropospheric Warming Trends
Publisher: American Meteorological Society
Abstract: Climate model simulations of the latter part of the twentieth century indicate a warming of the troposphere that is equal to or larger than the warming at the surface, while satellite observations from the Microwave Sounding ...
Effects of the South Asian Absorbing Haze on the Northeast Monsoon and Surface–Air Heat Exchange
Publisher: American Meteorological Society
Abstract: The effects of the south Asian haze on the regional climate are assessed using the National Center for Atmospheric Research Community Climate Model version 3 (CCM3) at the T42/L18 resolution. This haze, as documented during ...
Diagnosing Cloud Feedbacks in General Circulation Models
Publisher: American Meteorological Society
Abstract: In this study, it is shown that the NCAR and GFDL GCMs exhibit a marked difference in climate sensitivity of clouds and radiative fluxes in response to doubled CO2 and ±2-K SST perturbations. The GFDL model predicted a ...
