A Mathematical Model for Indian Ocean Circulation in Spherical Coordinate
In recent years, the Indian Ocean (IO) has been discovered to have a much larger impact on climate variability than previously thought. This paper reviews processes in which the IO is, or appears to be, actively involved. We begin the mathematical model with a pattern for summer monsoon winds. Three dimensional temperature and velocity fields are calculated analytically for the ocean forced by ...

متن کاملSupplementary material for: Mantle conveyor beneath the Tethyan collisional belt
The surface mechanical boundary conditions for most of our models are shear stress free (free slip), such that plate velocities are driven self-consistently by density contrasts within the mantle (Ricard and Vigny, 1989). The lithosphere in our models is defined rheologically as a relatively stiff layer from the surface to 100 km depth that is “broken” by weak zones of reduced viscosity, as in ...
متن کاملa new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
15 صفحه اولUpper mantle anisotropy: evidence from free oscillations
Isotropic earth models are unable to provide uniform fits to the gross Earth normal mode data set or, in many cases, to regional Loveand Rayleigh-wave data. Anisotropic inversion provides a good fit to the data and indicates that the upper 200 km of the mantle is anisotropic. The nature and magnitude of the required anisotropy, moreover, is similar to that found in body wave studies and in stud...
