Cheers, Allison ============ TITLE Understanding the Post-landfall Evolution of Tropical Cyclone Wind Field: From Idealized World to Real World ABSTRACT 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. 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. ??????????????????

The first talk normally starts at 11:00AM.? Each talk is typically 12 minutes long (similar to many professional meetings), with 8 minutes for questions. These talks will be presented via Zoom, with the following connection information: https://fsu.zoom.us/j/98491660566?pwd=NzBxNzN4LzdsbSs4R3B6RzliOGhhdz09 Meeting ID: 984 9166 0566 Passcode: 478314 Dec. 6th: Anna Smoot: Impact of surface currents on the atmosphere in the Gulf of Mexico Description: An initial proposal of how to investigate the atmosphere's response to changes in surface currents near the Mississippi River in the Gulf of Mexico using high-resolution aircraft observations from NASA and the WRF model. This presentation will examine the background and relevance of the problem, the approach of proposed study, and projected outcomes. David Zierden:Temperature Trends and Extreme Heat Description: We will examine trends in temperature at the global and national level and relate them to the occurrence of extreme heat (and cold) across Florida and the Southeast. Increasing temperature and changing extremes are impacting natural and developed landscapes as well as agriculture and human health. Zhaohua Wu: Waves in a Spatially Varying Mean Flow Description: How hydrodynamical waves change in space and time in a spatially varying mean flow has been a long-lasting pursue in the field of fluid mechanics and its related fields, such as atmospheric sciences and physical oceanography. Although pioneers from Cambridge school, such as G. B. Whitham and F. P. Bretherton, have identified conservative quantities, such as "adiabatic invariant" and "wave action" under wave packet assumptions in 1960s, the applicability of these conservative quantities in the real world is hindered by the conceptual mismatch between waves being a field and conservative quantities being associated with 'particles'.?On the other hand, due to the previous lack of adequate mathematical tools to analyze real world waves, the Fourier transform-based global analysis methods have led to?numerous misidentifications and misinterpretations of local wave activities, leading to a gap between theoretical understandings and observation of waves. Thus, filling this gap has been a long-lasting and is also an urgent challenge. -------------- next part -------------- An HTML attachment was scrubbed...
