[Eoas-seminar] COAPS Short Seminar Series - Monday Sept. 12th at 11:00AM - revised

[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

Oct. 3rd:

Kyra Britton: Application of High-Resolution Winter Seasonal Climate 
Forecasts for Streamflow Prediction in Central Florida

Description: Current global climate models typically run at a resolution 
of 100 km, which is too coarse to adequately resolve the coastlines and 
watersheds of Florida. Previous researchers created a reforecast of five 
environmental variables for a period of 22 years by dynamically 
downscaling a global model, thus giving more accurate regional data for 
temperature, evaporation, surface and root level soil moisture, and 
surface temperature. In this project, I attempt to define the 
relationship between these five reforecasted variables and the 
streamflow of several watersheds in Central Florida using statistical 
techniques, with the end goal of creating a streamflow forecast that 
will assist water utility managers in decision making


        Xiaobiao Xu: Importance of vertical resolution in an isopycnic
        ocean model

Description: In contrast to the large volume of studies focused on the 
importance of the horizontal resolution in oceanic general circulation 
models, the importance of vertical resolution has been largely 
overlooked. This study documents the sensitivity of modeled large-scale 
circulation to its vertical resolution used in an isopycnic model, at 
two horizontal resolutions of 1/12º and 1/50º, respectively. The results 
show that (1) at 1/12º, the large-scale circulation is not very 
sensitive to its vertical resolution and the number of layers required 
to obtain a reliable large-scale circulation in isopycnic model is less 
than that in a level model. (2) when the horizontal resolution is 
increased from eddying (1/12º) to submesocale eddy enabling (1/50º), the 
sensitivity of model solution to vertical resolution varies and the 
vertical resolution needs to be increased accordingly.

Mark Bourassa (and Jackie May): Importance of Resolution in 
Current-Related Air-Sea Coupling

The Navy's coupled ocean/atmosphere model is used to show that model 
resolution impacts the sign of the vorticity of surface winds.  Physics 
contributing to the model's boundary-layer vorticity is examined to 
interpret this result. The coupling between currents and wind stress 
will be reviewed as part of this explanation, then extended to include 
vorticity. Modeling results are used to show the impacts of the related 
changes in atmospheric boundary-layer processes.
