Project Type: Research

DESCRIPTION: We propose a project focused on studying tropical cyclones (TCs) in a new version of the NASA GISS climate model at 0.5 degree (50 km) horizontal grid spacing. Our project will have two components. In the first, we will experiment with physics and numeric parameters to develop a model that will be competitive for the study of tropical cyclones on the global scale. In the second, we will use the model for scientific studies of tropical cyclones and climate.

OUTCOMES: Improved the NASA GISS Climate model by making it able to simulate the Madden-Julian oscillation (MJO). Diagnosed MJO and tropical cyclones simulated by the model.
