Scientific Program: Coherent structures are ubiquitous
in atmosphere and ocean, and clarifying their mechanism is
directly related to delineating important aspects of
geophysical turbulence. The purpose of this workshop is to
survey the functions and features of coherent structures in
geophysical turbulence by exchanging ideas from the theory,
experiment/observation and computation. The following three
topics are planned to be discussed in the workshop:
In the past few years great progresses have been made in identifying new instability mechanisms of coherent structures in stratified and rotating flows (elliptic, hyperbolic, helical centrifuge, inertial and zigzag instabilities). We consider how these instabilities may affect the mechanisms of vortices and waves in rotating stratified flows.
Having a clear insight on the energy cascade mechanism in relation with coherent structures in geophysical turbulence is very crucial to build well-defined and reliable turbulence models for the weather and climate forecast.
Stirring and mixing are important in understanding the overall transport mechanisms in geo fluid dynamics as well as in engineering fluid dynamics. Transport of various geophysical quantities such as moisture, heat, salinity is a key ingredient for better prediction of atmosphere and ocean beyond the transport of energy and momentum for basic turbulence.
