[Eoas-seminar] COAPS Short Seminar Series - Monday at 11:00

[eoas-seminar at lists.fsu.edu]

These talks are usually scheduled for the first Monday of each month. 
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

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.
