GFDL Informal Seminar

Mon, Jun 22, 2020, 10:30 am to 11:30 am

The ocean transports vast amounts of heat around the planet, helping to regulate regional climate. In this talk I will discuss a framework that relates the ocean's meridional heat transport to the diabatic processes of air-sea heat fluxes and mixing that move heat across temperature classes (i.e. the ocean's diathermal heat transport). Applied to global MOM5 and ACCESS-OM2 simulations the framework emphasizes the role of surface heat gain and mixing in the eastern tropical Pacific and the exchange of heat between the Indo-Pacific and Atlantic basins. Turbulent mixing (both explicitly parameterized and numerical) plays a key role by moving heat from the warm, shallow Indo-Pacific circulation to the deeper-reaching Atlantic circulation and to the cold isotherms that outcrop in the North Atlantic. I will also discuss the use of the framework for estimating numerical mixing in realistic global model simulations as well as its sensitivity to resolution and explicit physics parameterizations.
