- Mid-latitude atmosphere-ocean coupled interactions
Is interannual variability in mid-latitude marine climate due to a
coupled interaction between atmosphere and ocean, or are they non-interacting
random fluctuations? What sets the geographic shapes of these fluctuations,
and their behavior in time? In my thesis work, I developed simple models
of mutually-coupled atmosphere-ocean interaction, and compared them with
alternative "one-way" passive response mechanisms, and with observed data.
I also investigated the atmospheric stationary wave patterns most responsive
to forcing by sea-surface temperature anomalies or other processes.
Future work will compare the coupled dynamics of these simple models with
patterns observed in coupled GCMs.
- Dynamics of "Snowball Earth"
There is geological evidence that 700 million years ago, the Earth
might have been globally glaciated. However, many coupled GCMs are unable
to realize such a state. Are the GCMs in error, or have the observations
been misinterpreted? I am currently studying the ability of thick layers
of sea ice to flow glacially, thus carrying ice into lower latitudes. Future
work will investigate the ability of atmospheric methane fluctuations to
create or terminate snowball conditions.
- Europan Ocean Dynamics
Analysis of Voyager and Galileo data suggests that Jupiter's moon Europa
probably has a thick layer of liquid water beneath its icy crust. If this
layer exists, it is warmed by geothermal heat from below, a situation radically
different than in the Earth's ocean. The ocean dynamics may be similar
to that of "Snowball Earth". What are the global and local features of
the circulation of such an ocean? How is heat transported within the ocean
and communicated to the icy surface layer? How does fluid motion and heat transport
affect the surface geology?
- Early Mars
Several billion years ago, Mars seems to have had liquid water running
over its surface, implying that it was far warmer than today. This warming
might have been achieved by a thick blanket of carbon dioxide, in both gaseous
form and in optically-thick dry ice clouds. How does such an unusual atmosphere
move, transport and release heat and moisture, and interact with the surface?
