General circulation models (GCMs) of the global atmosphere are a key tool for climate research. They represent atmospheric dynamics, physics, and chemistry with mathematical equations, which are then solved on a threedimensional grid that spans the globe. Computer capabilities currently limit the grid resolutions in the global GCMs that are used to simulate Earth’s climate and make warming pred...

This paper summarizes the ocean surface net energy flux simulated by fifteen atmospheric general circulation models constrained by realistically-varying sea surface temperatures and sea ice as part of the Atmospheric Model Intercomparison Project. In general, the simulated energy fluxes are within the very large observational uncertainties. However, the annual mean oceanic meridional heat trans...

Understanding the effects of climate variability and extremes on crop growth and development represents a necessary step to assess the resilience of agricultural systems to changing climate conditions. This study investigates the links between the large-scale atmospheric circulation and crop yields in Europe, providing the basis to develop seasonal crop yield forecasting and thus enabling a mor...

—Uncertainties in the surface wind field have long been recognized as a major limitation in the interpretation of results obtained by oceanic circulation models. It is especially true in the tropical oceans, where the response to wind forcing is very strong on short time scales. The purpose of this paper is to show that these uncertainties can be greatly reduced by using spaceborne wind sensors...

. introduction global warming and its result, climate change is an important subject investigated especially in the recent decades by researchers throughout the world. in these studies, at first, climatic parameters changes are investigated. considering many uncertainties in the parameters estimation, it is better to choose a method in order to study and analyze the uncertainty band due to diff...
