Abstract: Solutions of the linearized balance equations over a sphere are presented and compared with the Laplace's tidal equations results obtained by Longuet-Higgins. On these lines, this study searches for a partial answer ...

Abstract: It is proposed that a possible mechanism for the occurrence of severe droughts over northeast Brazil is the establishment of a thermally direct local circulation which has its ascending branch at about 10°N and its descending ...

Abstract: Comparisons of performance of climate forecast methods require consistency in the predictand and a long common reference period. For Brazil's Nordeste, empirical methods developed at the University of Wisconsin use preseason ...

Abstract: Thermostatically controlled loads (TCLs) account for more than onethird of the U.S. electricity consumption. Various techniques have been used to model TCL populations. A highfidelity analytical model of heterogeneous TCL ...

Abstract: This paper derives linear quadratic regulator (LQR) results for boundarycontrolled parabolic partial differential equations (PDEs) via weak variations. Research on optimal control of PDEs has a rich 40year history. This ...

Abstract: This work introduces a new robust motion control algorithm using partial state feedback for a class of nonlinear systems in the presence of modelling uncertainties and external disturbances. The ...

Abstract: A baroclinic stability analysis is performed for a simple family of zonal shear profiles over a sphere, using a two-layer, quasi-geostrophic model. The stability properties and the structure of the most unstable waves are ...

Abstract: This study presents an evaluation of a seasonal climate forecast done with the International Research Institute for Climate Prediction (IRI) dynamical forecast system (regional model nested into a general circulation model) ...
