Toward the end of the Pleistocene, archaic humans in Eurasia such as the Neanderthals and Denisovans were completely replaced by anatomically modern humans dispersing from Africa. Understanding the causes of […]
The physical structure of the upper ocean is an important control on ocean-atmosphere exchange of momentum, heat, freshwater, and gases such as carbon dioxide. It also regulates the distribution of […]
In this talk, we present results from spectral nudging experiments with a coupled climate model. These experiments aim to address the question how recent extreme events would unfold in +2K […]
Turbulence generated by sheared motions can have a large impact on the mixing of properties in both the ocean and atmosphere. There is a need to elucidate the factors controlling […]
Extreme events, i.e., the normally rare occurrences when a system is far outside its norm, severely impact organisms and ecosystem on land. Yet, in comparison, our understanding of such extreme […]
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 […]
