The global wild marine fish harvest increased fourfold between 1950 and its current peak, reflecting interactions between human and ecological drivers. This talk will examine these interactions in an Earth […]
We investigate the relationship between convective available potential energy (CAPE), precipitation, the number and size of storms and overshooting tops, and lightning stroke density (f) over the Central America region. […]
Terrestrial ecosystems play an integral role in regulating Earth’s climate through their cycling of carbon, water, and energy. Humans are altering these fluxes by perturbing terrestrial ecosystems through land use […]
We will conclude by looking at the age of a number of tracers, taking examples from the stratosphere and Pacific Ocean.
This talk will present the concept of convective aggregation on the mesoscale in idealized cloud resolving models, in highly simplified stochastic models and in the latest observations in the tropical […]
Tracers that have a time history of input can be used to provide information on when the water or air was last at the surface. Mixing complicates the issue. We […]
ERA5 is ECMWF’s latest comprehensive reanalysis of meteorological and related observations made over multiple decades. It has been released in final form covering 1979 onwards, with an improved (ERA5.1) version […]
I will introduce the concept of transit time distributions and how they can be used to consider what influences the properties of water and air at a particular location and […]
We will continue to discuss Lagrangian Coherent Structures, in particular focusing on the impact of hyperbolic points, the braking of transport barriers, and the dispersion of larvae around Hawaii.
Topics covered include: Eulerian versus Lagrangian approaches, particle trajectories and phase space, material surfaces and invarient manifolds, stable and unstable manifolds and their detection.
