"Ice clouds as nonlinear oscillators”
Abstract: Ice clouds are, as all clouds, important components of the
Earth-Atmosphere system, e.g., influencing the energy budget of the
system via interaction with radiation. However, our understanding of ice
clouds in the low temperature regime (T<235K) is still limited. For
investigating ice clouds in a mathematically consistent way, we derive a
three dimensional system of ordinary differential equations and use
methods from theory of dynamical systems to analyze this system.
Surprisingly, the system results into a nonlinear oscillator with two
Hopf bifurcations and some other symmetries. Although the model is quite
simple, the agreement with real measurements is quite good, so it might
be used for further investigations, e.g., in terms of coupled
oscillators or nonlinear forcings.

Edriss Titi (DAMTP, U. Cambridge)
“The Navier-Stokes, Euler and Other Related Geophysical Equations"
Abstract: In this talk I will present the most recent advances
concerning the questions of global regularity of solutions to the
three-dimensional Navier–Stokes and Euler equations of incompressible
fluids. Furthermore, I will also present recent global regularity (and
finite time blow-up) results concerning certain three-dimensional
geophysical flows, including the three-dimensional viscous
(non-viscous)“primitive equations” of oceanic and atmospheric dynamics.
