Abstract: A hemispheric general circulation model, with fixed zonally averaged cloud cover, was used to investigate the climatic impact of increased albedo of low-level clouds caused by atmospheric pollution. The albedo of these ...

Abstract: The role of nonlinear interactions in the climatic system in contributing to variability at both spatial and temporal levels is poorly understood. To gain some insight into the possible role of nonlinearities an elementary ...

Abstract: As a continuation of the previous experiments in this series, the 18-vertical-level general circulation model was used to investigate the large-scale diffusion of a further two tracers in the stratosphere. In the present ...

Abstract: It is shown that when rate constants confirmed by recent laboratory studies are used in photochemical O3 calculations unacceptably high O3 concentrations and total O3 amounts are obtained. In order to account for this ...

Abstract: A primitive equation general circulation model has been developed to simulate the atmosphere from the surface to 100 km. The model was based on the semispectral technique and has 15 zonal wavenumbers and 40 grid points ...

Abstract: The hydrologic cycle has been included in a stereographic model of the Northern Hemisphere previously used as a dry model. The model had 18 vertical levels distributed between the surface and 37.5 km and was run out for ...

Abstract: In view of the possible climatic importance of volcanic eruptions an initial attempt has been made to simulate the particulate impact of a large eruption on the general circulation via its interaction with the incoming ...

Abstract: Hindcasts for the period 1972?92 have been made using the two-tiered method. This involved forcing a global atmospheric model with sea surface temperature anomalies for the low-latitude Pacific Ocean generated with the ...

Abstract: A new type of global general circulation model has been developed consisting of a finite difference representation in a single meridional-height plane, with the zonal variance of the atmospheric fields being treated by ...

Abstract: The Commonwealth Scientific and Industrial Research Organisation (CSIRO) Mark 2 global coupled climatic model has been used to generate a 10 000-yr simulation of ?present? climate. The resultant dataset has been used to ...
