The Link between Gulf Stream Precipitation and European Blocking in General Circulation Models and the Role of Horizontal Resolution
Kristian Strommen, Simon L. L. Michel, Hannah M. Christensen
Past studies show that coupled model biases in European blocking and North Atlantic eddy-driven jet variability decrease as one increases the horizontal resolution in the atmospher…
Through a Jet Speed Darkly: The Emergence of Robust Euro-Atlantic Regimes in the Absence of Jet Speed Variability
J. Dorrington, K. Strommen
Euro-Atlantic regimes are typically identified using either the latitude of the eddy-driven jet, or clustering algorithms in the phase space of 500hPa geopotential height (Z500). H…
Jet Latitude Regimes and the Predictability of the North Atlantic Oscillation
Kristian Strommen
In recent years, numerical weather prediction models have begun to show notable levels of skill at predicting the average winter North Atlantic Oscillation (NAO) when initialised o…
The Sensitivity of Euro-Atlantic Regimes to Model Horizontal Resolution
K. Strommen, I. Mavilia, S. Corti +5
There is growing evidence that the atmospheric dynamics of the Euro-Atlantic sector during winter is driven in part by the presence of quasi-persistent regimes. However, general ci…
The impact of stochastic physics on climate sensitivity in EC-Earth
K. Strommen, P. A. G. Watson, T. N. Palmer
Stochastic schemes, designed to represent unresolved sub-grid scale variability, are frequently used in short and medium-range weather forecasts, where they are found to improve se…
Signal and noise in regime systems: a hypothesis on the predictability of the North Atlantic Oscillation
Kristian Strommen, Tim N. Palmer
Studies conducted by the UK Met Office reported significant skill at predicting the winter NAO index with their seasonal prediction system. At the same time, a very low signal-to-n…
