<b class="">ABSTRACT</b></div>
<div style="font-family: Candara, Optima, sans-serif; font-size: 16px;" class="">
Post-landfall tropical cyclones (TCs) bring significant hazards, considered as the major environmental challenge for U.S. coastal and even inland regions. This hazard risk could be amplified given the potential that landfalling TCs move and decay more slowly
in a warming climate. However, the lack of physical understanding of post-landfall TC greatly inhibits our ability to predict and mitigate hazards in both short-term and long-term risk assessment.</div>
<div style="font-family: Candara, Optima, sans-serif; font-size: 16px;" class="">
<span style="font-size: 12pt;" class="">Here in the presentation, I will introduce how we advance the understanding of the post-landfall TC wind field. In my previous work, I investigated the inland evolution of the complete TC wind field by idealizing the
complicated landfall process as a transient response of a mature axisymmetric storm to instantaneous surface forcings associated with landfall. In the idealized landfall experiment, the surface beneath a mature storm is roughened or/and dried, each over a
range of magnitude. I systematically tested the response and analyzed how each forcing ultimately causes the storm to weaken but via different mechanistic pathways. This part of the work provides a mechanistic foundation for understanding the inland evolution
of real storms in nature, and generates a dataset of idealized landfall experiments to test existing TC theories. For TCs over the ocean, existing theoretical predictions for the intensity and wind field have been advanced and tested with observations but
not yet applied to post-landfall storms. As a natural next step, I explored the extent to which existing theory formed for TCs over the ocean can explain the response of the intensity and full wind field to idealized landfalls and how we can modify existing
theory for inland TCs. This part of the work indicates the potential for existing theory to predict how the TC wind field evolves after landfall. Accounting for the complexities in real-world landfalls, my current work is testing theoretical understandings
against various observations and assessing NOAA T-SHiELD real-time post-landfall forecast for U.S. landfalling TCs. This work would help us link physical understanding to real-world cases and evaluate the performance of the leading operational model on TC
post-landfall evolution, which is essential for improving the forecasts on any timescale and the inland TC risk assessments.</span></div>
