Abstract

This study examines tropical cyclones (TCs) that are simulated by CMIP6 HighResMIP global climate models (GCMs). Previous studies have examined GCM-simulated TC structures, often focusing on wind structures and upper-level warm-core anomalies. However, not many studies have evaluated TC rainfall structures in GCM simulations. In this work, we perform an observation-based evaluation of GCM-simulated TCs by comparing against the multiple satellite-based rainfall retrievals. This process-oriented diagnosis can help determine which GCMs produce more realistic TCs than others in terms of key TC processes. Preliminary results indicate that GCM-simulated TCs in CMIP6 HighResMIP simulations tend to overestimate the inner-core rainfall in comparison to the satellite-derived rainfall at comparable intensity.
