Modeling high-impact weather and climate: Lessons from a tropical cyclone perspective

This challenge is driving fresh approaches to assess high-impact weather and climate. Recent lessons learned in modeling high-impact weather and climate are presented using the case of tropical cyclones as an illustrative example.

Through examples using the Nested Regional Climate Model to dynamically downscale large-scale climate data, the need to treat bias in the driving data is illustrated. Domain size, location, and resolution are also shown to be critical and should be guided by the need to: include relevant regional climate physical processes; resolve key impact parameters; and to accurately simulate the response to changes in external forcing.
