Multiscale simulation of upper ocean dynamics during monsoon intraseasonal oscillations
Abstract
The intraseasonal oscillations (ISO) in the monsoon constitute a large-scale coupled atmosphere-ocean phenomenon.The properties of the ocean surface layer that mediate the air-sea coupling depend crucially on finescale turbulence as well as the regional-scale circulation in the North Indian Ocean. We propose high-resolution simulations to characterize the multiscale processes that determine the upper ocean structure. Stand-alone LES with uniformly high resolution will be used in O(1-10) km horizontal domains and and the recently developedStratified Ocean Model with Adaptive Mesh Resolution (SOMAR-LES) that has two-way nested LES will be used in O (10-100) km horizontal domains. The simulations will help setup and interpret high-resolution observations of the surface layer. The pro"posed work will help clarify the distinct roles of Ekman dynamics, buoyancy inputs, eddies and fronts on turbulent upper-ocean proce"sses in the North Indian Ocean.
