Circulation types for European regions (1948–2021)

Listed in Teesside University Research Data Repository

Circulation types were calculated for five regions located across the central latitude strip of Europe (along the 50° latitude).

Description

The regions correspond to 5° × 5° longitude–latitude grid boxes stretching from Western to Eastern Europe, with centers at [5°E, 50°N], [10°E, 50°N], [15°E, 50°N], [20°E, 50°N], and [25°E, 50°N]. Circulation types (CTs) were derived from three circulation indices (flow strength, direction, and vorticity; Jenkinson & Collison, 1977).

Circulation indices were calculated in a daily time step using the sea level pressure from the NCEP/NCAR reanalysis (Kalnay et al., 1996). Based on the Lamb (1972) catalogue, 27 CTs adjusted for each region were derived from the indices (Blenkinsop et al., 2009). A detailed description of the classification of daily patterns into CTs was published by Lhotka et al. (2020) for Central Europe, and the procedure was analogous for the other regions under study.
