Abstract: A large number of uncoupled integrations with an idealized general circulation model are carried out to investigate the linearity of the atmospheric quasi-equilibrium response to North Atlantic sea surface temperature (SST) ...

Abstract: This observational study investigates the impact of North Atlantic synoptic-scale wave breaking on the North Atlantic Oscillation (NAO) and its connection with the stratosphere in winter, as derived from the 40-yr ECMWF ...

Abstract: Dynamical stratosphere?troposphere coupling through a response of baroclinic waves to lower stratospheric flow conditions is investigated from an initial value approach. A series of adiabatic and frictionless nonlinear ...

Abstract: A reduced-gravity double-gyre ocean model is used to study the influence of an additive stochastic wind stress component on the regime behavior of the wind-driven circulation. The variance of the stochastic component ...

Abstract: The effect of vegetation extremes on the general circulation is estimated by two atmospheric GCM simulations using global desert and forest boundary conditions over land. The difference between the climates of a ?green ...

Abstract: The impact of an unsteady wind forcing on oceanic low-frequency variability is conceptually studied using a reduced-gravity shallow-water model. A time-averaged wind forcing and a simple ocean?atmosphere coupling is completed ...

Abstract: A tangent linear adjoint for a low-resolution dynamical model of the atmosphere is used to derive the optimal forcing perturbations for all state variables such that after a specified lead time the model response has a ...

Abstract: The observed low-frequency variability of the zonally averaged atmospheric circulation in the winter hemisphere is found to be amenable to an interpretation where the subtropical jet is flanked by a secondary midlatitude ...

Abstract: everal studies show that the anomalous long-lasting Russian heat wave during the summer of 2010, linked to a long-persistent blocking high, appears mainly as a result of natural atmospheric variability. This study analyzes ...

Abstract: he impact of mountains and ice sheets on the large-scale circulation of the world?s oceans is investigated in a series of simulations with a new coupled ocean?atmosphere model [Oregon State University?University of Victoria ...
