Mixing and general circulation dynamics : theory and observations
… studies the role of cross-isopycnal mixing in general circulation dynamics, from both the theoretical and observational points of view. The first two chapters discuss some theoretical aspects of cross-isopycnal mixing in the oceans. In chapter one, an integral constraint relating the interior …

Adaptive error estimation in linearized ocean general circulation models
… data from the ATOC project, and the MIT General Circulation Model (GCM). A reduced state linear model that describes large scale internal (baroclinic) error dynamics is used. The MT method, closely related to the maximum likelihood methods of Belanger (1974) and Dee (1995), is shown to be …

Zonally symmetric monsoon dynamics in a general circulation model
The MIT general circulation model is used with simplified setup to study steady zonally averaged monsoon circulations. Two dimensional model runs are made with a zonally symmetric continent north of 15N and a slab ocean of uniform sea surface temperature to study the applicability of axisymmetric …

General Circulation Model Regional Predictions Using MOS techniques: Seasonal Forecasting
Ocean and atmospheric Coupled Global Climate Models (CGCMs) have been widely used to provide more accurate and coherent seasonal forecasts. However, they still show some limitations. Model Output Statistics (MOS) approaches may improve performance if observed and forecast values are available for a …

The representation of cloud cover in atmospheric general circulation models
… one of the most crucial and uncertain aspects in General Circulation Models (GCMs) of the atmosphere, which are used for both Numerical Weather Prediction and the simulation of climate. It is therefore important to constantly monitor and improve the performance of cloud parametrizations in those …

Catchment Scale Downscaling of Hydroclimatic Variables from General Circulation Model Outputs
… considered the dominant cause of climate change. General Circulation Models (GCMs) are used for the projection of climate into future, accounting for the GHG concentrations. However, the coarse spatial resolution of GCM outputs does not permit their direct use in catchment scale studies. Therefore …

On the maintenance of blocking anticyclones in a general circulation model
… appear in perpetual January simulations of a general circulation model are examined. Blocks in three geographical regions are studied: the North Pacific, the North Atlantic and Western North America. Local time-averaged balances of vorticity and heat are evaluated for composite cases of …

The Role of diapycnal mixing in coupled atmosphere-ocean general circulation models
… important role in the meridional overturning<br/>circulation (MOC). Previous idealised experiments and simplified theory suggest that the strength of<br/>the MOC and the ocean heat transport scale with the v. This study investigates the dependence of<br/>the MOC and other parameters on v using …

Sensitivity of a general circulation inverse model to sub-grid scale parametrization coefficients
Ocean modellers seek to understand the circulation of the oceans, or portions thereof, by developing models of the ocean they can solve. This tractability constraint forces ocean modellers to make choices. Naturally, they hope to make intelligent choices, but whenever a new model is being developed …
