COAPS Short Seminar Series
11:00 May 4th
Attend F2F (in 255 Research A) or Virtually (via Zoom)
https://fsu.zoom.us/j/92268262553

Meeting ID: 922 6826 2553
Talks are typically 12 minutes long with an additional 8 minutes for questions. This month our first talk will have the time for two typical talks.

Breaking Down the Effects of Current Feedback Coupling onto the Atmospheric Boundary Layer
By Kamran Chowdhury
Description: We use a paired current feedback (CFB) - no current feedback (NoCFB) modeling experiment to first capture thermal feedback of the ocean onto the atmosphere by itself (which is in both simulations), and then see what additional responses adding in current feedback does. The modeling experiment has a unique feature where the ocean is saved from the CFB run to the NoCFB run, allowing more effective comparison of a CFB and NoCFB atmosphere.

A Model-Based Study of Power Input to Hurricane Boundary-Layers
By Matt Weiberg
Description: Tropical cyclones act as massive atmospheric engines, drawing their power from the transfer of heat and moisture at the ocean surface. Despite advances in tracking where storms go, predicting rapid intensification remains a major challenge for forecasters. To better understand this explosive growth, we will use high-resolution computer simulations to examine exactly where and when energy enters the storm's inflow boundary layer. By measuring the power intake across different storm quadrants, we will identify which regions act as the primary fuel source and map how that internal structure evolves as the hurricane strengthens.

Ensemble versus time averaging: perspectives on mesoscale geostrophic eddy kinetic energy in the North Atlantic
By Luolin Sun
Description: Eddies are classically defined through Reynolds averaging—either via time averaging, as transient eddies, or ensemble averaging, as intrinsic ensemble eddies. Yet, a direct comparison between the transient and ensemble eddies have not been fully explored. We focus on the surface eddy kinetic energy defined via the two approaches, and examine their differences across spatial and temporal scales.
