Linking Cloud-Radiation Parameterization Performance to Large-Scale Dynamics

Parameterization of cloud-radiation interactions in an atmospheric general circulation model using a stochastic approach allows for a statistical representation of cloud field geometry. Previous work indicates that the stochastic approach to cloud-radiation parameterization performs better than typical plane-parallel algorithms in situations where the horizontal cloud fraction is between 0.2 an...

Large-Scale Ocean Circulation

The past 30 years have witnessed a rapid evolution of circulation theory. Much of the progress can be attributed to the intuition and physical balance that have emerged from the use of simple models that isolate important processes. Major contributions along these lines were made by Stommel, Welander, and others. An excellent presentation of the ideas together with a number of significant advan...

Extreme Associated Functions: Optimally Linking Local Extremes to Large-scale Atmospheric Circulation Structures

We present a new statistical method to optimally link local weather extremes to large-scale atmospheric circulation structures. The method is illustrated using July-August daily mean temperature at 2m height (T2m) time-series over the Netherlands and 500 hPa geopotential height (Z500) time-series over the Euroatlantic region of the ECMWF reanalysis dataset (ERA40). The method identifies pattern...
