✦ Synopsis

In this paper, a fully implicit numerical model of the three-dimensional thermohaline ocean circulation is presented. With this numerical model it is possible to follow branches of steady states in parameter space and monitor their linear stability. Also, transient flows can be computed allowing much larger time steps than those possible with explicit schemes. By using recently developed solvers for linear systems of equations and for generalized eigenvalue problems, results for reasonable spatial resolution can be obtained. Bifurcation diagrams and transient flows are computed for typical flows in a single hemispheric basin situation, with focus on (i) the performance of the methodology and (ii) the new type of information which can be obtained on these flows.

## Abstract We present a three‐dimensional (3D) semi‐classical ensemble Monte Carlo model newly developed to simulate a variety of nanoelectronic devices. The characteristics of the 3D model are compared with the widely used two‐dimensional (2D) models. The advantages of our model, in terms of accu

We present a three-dimensional cloud model designed for the study of formation and evolution of moist convective storms on the giant planets. This is a finite-difference model that solves the dynamic and thermodynamic equations forward in time under the anelastic approximation including microphysics
