Topics covered include: Eulerian versus Lagrangian approaches, particle trajectories and phase space, material surfaces and invarient manifolds, stable and unstable manifolds and their detection.
We will consider some basic properties of turbulent flows. Topics covered include: The Kolmogorov and Batchelor scales, flow instabilities, the turbulent kinetic energy equation, inferring turbulent diffusivity from measurements of […]
Can state-dependent effects of natural forcing resolve mismatches of simulated and reconstructed climate variability?
Temperature variability at the last Glacial Maximum was higher than during the Holocene. Can we extrapolate from this to a state-dependency of Earth surface temperature variability? Another explanation could be […]
Today we will consider the dispersion of pairs of particles and contrast the dispersion of particles in 3D and 2D turbulence.
Today we will consider dispersion in a Lagrangian framework and look at the classic GI Taylor paper “Dispersion by continuous movements”. We introduce the concept of anomalous dispersion, an example […]

Southern Oscillation (ENSO) are usually evaluated by comparing them to observations using a multitude of metrics. However, this approach can not provide an objective summary metric of model performance. Here we […]
Lakes are a critical natural resource that contain a large majority of Earth’s accessible surface freshwater, support important biodiversity and provide many benefits to people around the world. However, lakes […]
Artificial intelligence (AI) and big data are bringing innovations to many research fields that have a direct social impact. In this talk, I’d like to share recent efforts on research […]
One of the most intriguing facets of the climate system is that it exhibits variability across all temporal and spatial scales; pronounced examples are temperature and precipitation. The structure of […]
