Climatology of the SKYHI troposphere-stratosphere-mesosphere general circulation model

Abstract

The long-term mean climatology obtained from integrations conducted with different resolutions of the GFDL "SKYHI' finite-difference general circulation model is examined. A number of improvements that have been made recently in the model are also described. The versions considered have 3° × 3.6°, 2° × 2.4°, and 1° × 1.2° latitude-longitude resolution, and in each case the model is run with 40 levels from the ground to 0.0096 mb. The integrations all employ a fixed climatological cycle of sea surface temperature. Over 25 years of integration with the 3° model and shorter integrations with the higher-resolution versions are analyzed. Attention is focused on the December-February and June-August periods. -from Authors
