Recent studies revealed that the tropical Atlantic Ocean has experienced the most pronounced warming trend over the 20th century. Since many extreme climate events affecting the U.S.—such as hurricanes, severe precipitation and drought—are influenced by the conditions in the tropical Atlantic, the ability to simulate accurately the climate mean and variability in that region is crucial. Unfortunately, almost all global climate models exhibit large biases in their simulations of the tropical Atlantic climate, and their resolution is too coarse to resolve some of the processes responsible for such biases.
We are developing a comprehensive high-resolution coupled regional climate model (CRCM) for the Atlantic sector to address the tropical bias issue. Currently based on the coupling between NCAR’s WRF (atmosphere) and Rutgers/UCLA ROMS (ocean), the model will be extended to include the coupling with CLM (land) within the general framework of CPL7.
Details regarding the implementation of the coupled model will be discussed along with current results.
Dr. Raffaele Montuoro is Senior Lead IT Consultant with the Texas A&M University Supercomputing Facility in College Station, TX. He joined Texas A&M University in 2004, after working as IT consultant for Eutelsat SA in Paris, France. Dr. Montuoro holds a PhD in Theoretical Chemistry from the Scuola Normale Superiore di Pisa, Italy, and has developed innovative numerical models used for accurate calculations of photoionization phenomena. In 2010, some of his recent work in code optimization has been featured in the national press. Dr. Montuoro is currently collaborating with investigators at Texas A&M and PNNL to create a comprehensive high-resolution coupled regional climate model for simulations over the Atlantic Ocean.
