Properties of nonuniform grids used in ocean general circulation models

ENSO Bred Vectors in Coupled Ocean–Atmosphere General Circulation Models

The breeding method has been implemented in the NASA Seasonal-to-Interannual Prediction Project (NSIPP) coupled general circulation model (CGCM) with the ultimate goal of improving operational seasonal to interannual climate predictions through ensemble forecasting and data assimilation. This is the first attempt to isolate the evolving ENSO instability and its corresponding global atmospheric ...

Transient Climate Response in Coupled Atmospheric–Ocean General Circulation Models

The equilibrium climate sensitivity (ECS) has a large uncertainty range among models participating in the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4) and has recently been presented as ‘‘inherently unpredictable.’’ One way to circumvent this problem is to consider the transient climate response (TCR). However, the TCR among AR4 models also differs by more tha...

Evaluating the performance of Atmosphere-Ocean Global Circulation Models (AOGCM) in simulating temperature variable in Ahwaz and Abadan stations

Climate changes caused by global warming has presented challenges to human society. Studying the Changes of climate variables in the future decades by using output data’s of Atmosphere-Ocean Global Circulation Models (AOGCM) is a way of perusing climate fluctuation in a region. In this study, the focus is on the AOGCM proceeds in simulating of variable temperature in Ahwaz and Abadan stations. ...
