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 […]
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 […]
This series of talks aims to be an introduction to the various processes that affect the This series of talks aims to be an introduction to the various processes that […]
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 […]
Multidecadal variations in North Atlantic sea surface temperatures are linked to areas far beyond that region, via atmospheric teleconnections. We take advantage of one such linkage, to reconstruct multi-decadal variations […]
