North Sea Caspian Pattern (NCP)
The NCP dataset presented here is calculated from the normalised 500hpa pressure difference between averages of North Sea (0°E, 55°N and 10°E, 55°N) and North Caspian (50°E, 45°N and 60°E, 45°N) centres of action. This is the same formulation used as Kutiel and Benaroch (2002) who selected these locations by use of linear correlation between pressure grid points and a GIS approach.
