Earth System Model
Entry ID: GFDL_ESM


Summary
Abstract: ESM2.1, evolved directly from GFDL’s successful CM2.1 climate model (Delworth et al. 2006 ). Building on this, we produced two new models representing ocean physics with alternative numerical frameworks to explore the implications of some of the fundamental assumptions embedded in these models. The models differ mainly in the physical ocean component. In one model, ESM2M, pressure-based vertical coordinates are used along the developmental path of GFDL’s Modular Ocean Model version 4.1. In the other, ESM2G, an independently developed isopycnal model using the Generalized Ocean Layer Dynamics (GOLD) code base was used.

Comparison between these two models allows us to assess the sensitivity of the coupled climate-carbon system to our assumptions about ocean formulation. Both ESM2M and ESM2G utilize a more advanced land model, LM3, than was available in ESM2.1 including a variety of enhancements (Milly et al., in prep). While the models demonstrate similar overall scale fidelity, they have important differences in both their thermocline characteristics, deep circulation, ventilation patterns and El Nino variability that suggest critical roles for details of ocean configuration in the coupled carbon climate system.
