The workshop is being organized<br>by James Cho, Brad Marston, Jin-Song von Storch, and Paul Williams. <div>The deadline for applications is January 31, 2012;<br>applications can be submitted via the ACP website at URL<br><<a href="http://aspenphys.org/">http://aspenphys.org/</a>><br><br>As workshop organizers, we would particularly like to<br>encourage you to apply. We as organizers cannot guarantee<br>your admission to the workshop, because admission is granted<br>by the Admissions Committee of the Center rather than by<br>the organizers. The Admissions Committee will endeavor to<br>accommodate as many applicants as possible, but they will<br>not be able to admit everyone who applies. The committee<br>will give preference to participants who will attend for<br>the full three weeks of the workshop.<br><br>Description: <br>Stochastic processes can be used to model systems in which<br>two or more spatio-temporal scales interact. Turbulent<br>flows, weather, and climate are prime examples. Typically,<br>the small/fast scale is treated as a random influence on<br>the large/slow scale. The workshop will focus on improved<br>understanding of geophysical and astrophysical flows made<br>possible by stochastic modeling. In particular, advances<br>in computing power and algorithms permit a direct comparison<br>of stochastic models to numerical simulations. The power<br>and limitations of the stochastic approach need to be better<br>established, however. The tension between simple and complex<br>models will be explored within the context of how stochastic<br>approaches can address the enormous range of spatial and <br>process scales inherent in flow and climate systems. The <br>workshop will bring together climate scientists, <br>astrophysicists, applied mathematicians, and physicists to<br>stimulate interdisciplinary research in these directions.<br><br>Aspen workshops are known for their informality. There<br>are no proceedings, and participants come to talk with one<br>another about exciting ideas and problems rather than to<br>talk at one another about work already completed. New<br>research is often initiated and even completed in Aspen,<br>and there are numerous examples of influential papers and <br>areas of research that can trace their origins to an Aspen <br>workshop. There will be no more than 3 formal sessions <br>(lasting no more than 3 hours each) scheduled per week. <br>Thus Aspen workshops are quite different from most other<br>workshops and conferences. Each participant will receive<br>a weekly stipend to be applied toward their housing expense.<br>No support is available for salary, travel expenses, or<br>registration fees.<br><br>The Center and the City of Aspen are very family-friendly. <br>The town and the surrounding mountains offer many opportunities<br>to enjoy Colorado. Participants are encouraged to bring<br>their families along.<br><br>Please also pass on this announcement to anyone you feel<br>would be interested. Thank you.<br><br>Kinds regards,<br><br>James Cho, Brad Marston, Jin-Song von Storch, and Paul Williams</div><div><br></div><div><br><br></div></body></html>
