Ocean models are used to investigate how variations in surface heat fluxes and ocean heat transports contribute to variations of tropical Atlantic SSTs on decadal timescales. The observed patterns of variability, deduced from reanalyses of the National Centers for Environmental Prediction (NCEP), are found to involve the ocean’s response to variations in the strength of the northeast and southe...

In this study, the processes affecting sea surface temperature variability over the 1992–98 period, encompassing the very strong 1997–98 El Niño event, are analyzed. A tropical Pacific Ocean general circulation model, forced by a combination of weekly ERS1–2 and TAO wind stresses, and climatological heat and freshwater fluxes, is first validated against observations. The model reproduces the ma...

We present new thermal equilibrium solutions for optically thin and optically thick disks incorporating magnetic fields. The purpose of this paper is to explain the bright hard state and the bright/slow transition observed in the rising phases of outbursts in black hole candidates. On the basis of the results of three-dimensional MHD simulations, we assume that magnetic fields inside the disk a...

Advection-enhanced heat and mass transport from a single droplet neutrally suspended in simple shear flow has been studied using high-fidelity numerical simulation. The capillary number ranges 0.01 to 0.5, which encompasses the entire range of small deformation, large breakup droplets. Reynolds is 1, including regions both weak strong advection. temperature concentration are modeled as passive ...

—Seasonal temperature variation at any location is most strongly regulated by the annual cycle of solar insolation, which is controlled by latitude and orbital parameters; other factors are continentality, albedo feedbacks, stratification and advection, and water depth. Seasonal minima, maxima, and range vary with change in mean annual temperature (MAT) across latitudes; seasonal variation in o...

We consider an exponentially fitted discontinuous Galerkin method for advection dominated problems and propose a block solver for the resulting linear systems. In the case of strong advection the solver is robust with respect to the advection direction and the number of unknowns.

In the present study, analytical solutions are obtained for two-dimensional advection dispersion equation for conservative solute transport in a semi-infinite heterogeneous porous medium with pulse type input point source of uniform nature. The change in dispersion parameter due to heterogeneity is considered as linear multiple of spatially dependent function and seepage velocity whereas seepag...
