Abstract: Time-averaged vertically integrated 3D advections are inferred from heat and moisture budgets obtained from observations at the Surface Heat Budget of the Arctic Ocean (SHEBA) field experiment for April, May, June, and ...

Abstract: A persistent, weakly forced, horizontally extensive mixed-phase boundary layer cloud observed on 4?5 May 1998 during the Surface Heat Budget of the Arctic Ocean (SHEBA)/First International Satellite Cloud Climatology Project ...

Abstract: A new two-moment bulk microphysics scheme is implemented into the polar version of the fifth-generation Pennsylvania State University?NCAR Mesoscale Model (MM5) to simulate arctic mixed-phase boundary layer stratiform ...

Abstract: The GFDL ?SKYHI? general circulation model has been used to simulate the effect of the Antarctic ?ozone hole? phenomenon on the radiative and dynamical environment of the lower stratosphere. Both the polar ozone destruction ...

Abstract: An enhanced National Center for Atmospheric Research (NCAR) integrated sounding system (ISS) was deployed as part of the Vertical Transport and Mixing (VTMX) field experiment, which took place in October of 2000. The ...

Abstract: Winter storm-track activity over the Northern Hemisphere and its changes in a greenhouse gas scenario (the Special Report on Emission Scenarios A1B forcing) are computed from an ensemble of 23 single runs from 16 coupled ...

Abstract: The role of bromine compounds in the photochemistry of the natural and perturbed stratosphere has been reexamined using an expanded reaction scheme and the results of recent laboratory studies of several key reactions. The ...

Abstract: An overview is given of the First ISCCP Regional Experiment Arctic Clouds Experiment that was conductedduring April?July 1998. The principal goal of the field experiment was to gather the data needed to examine the impactof ...
