Poleward meridional heat transports are the fundamental driver of the inhomogeneous solar radiation absorption by the Earth’s climate system that sets the general circulation of the atmosphere and ocean in […]
The evolution of thermal anomalies in the ocean are key to climate fluctuations such as El Nino and longer term decadal variability. Away from the surface, the propagation of thermal […]
A third of CO2 released by burning fossil fuels since the industrial revolution has ended up in the ocean. The absorbed CO2 subsequently lowers the pH level, and the temperature of the […]
Midlatitude weather systems, such as extratropical cyclones, fronts, and their embedded thunderstorms are vital for the day-to-day variability of precipitation and winds. We have used a number of objective techniques to […]
This presentation details work within my group which shows that where it rains more often, it also rains harder. When grouping precipitation into regions of similar wet day frequency, regardless […]
Climate variability has distinct spatial patterns with the strongest signal of sea surface temperature (SST) variance residing in the tropical Pacific. This interannual climate phenomenon, the El Niño-Southern Oscillation (ENSO), […]
The Gulf Stream Convergence Zone is a dipole of long-term averages of surface-wind divergence and convergence located over the Gulf Stream’s cold and warm flanks, respectively. This divergence pattern has […]
Compound events, e.g. drought and heat, can influence ecosystem activity directly, affecting plant functioning, but also indirectly by triggering ecosystem disturbances. These impacts are further modulated by forest condition and […]
We have simulated a large set of idealized simulations with the Norwegian Earth System Model (NorESM2) to explore the Earth system response to net-zero and net-negative CO2 emissions. Our simulations […]
Abrupt permafrost thawing is expected to release large amounts of greenhouse gasses to the atmosphere, creating a positive feedback to climate warming. There is, however, still large uncertainty in the […]
