Investigating interactions between the tropical cyclone inner core and near environment and their impacts on intensity change
Abstract
Funds are provided to conduct research to investigate how environmental factors (e.g., vertical shear, midlevel RH, low-level equivalent potential temperature, SST) affect the TC inner-core latent heating structure and distribution, which are important modulators of rapid intensification (RI) processes. How those environmental impacts are communicated from the TC near-environment to the inner core and how they vary across multiple time scales (e.g., diurnal, convective, mesoscale) is key to understanding and predicting their effect on inner-core RI processes. To test the overarching hypothesis, observations from a variety of manned (e.g., NOAA P-3 Orions and G-IV) and unmanned platforms will be collected during the TCRI field campaigns. These observations will provide data for investigating the kinematic and thermodynamic characteristics of the target regions to gain an understanding of sources of uncertainty and sensitivity in NWP models, and why they affect TC intensification and RI.
