Dataset
Cyclones, fronts, thunderstorms, and their concurrence: Seven categories of European storm type identified in ECMWF ERA5 over the North Atlantic region
Abstract
A dataset of storm types over Europe developed for the purpose of understanding the importance of these storm types for precipitation in the region.
The files are gridded NetCDF format containing one month of data each. They are the storm types identified from the European Centre for Medium-Range Weather Forecasts (ECMWF) reanalysis dataset (ERA5) identified over the North Atlantic/European region.
The storm types are numbered from 1-7 as follows:
1 - cyclone only
2 - front only
3 - thunderstorm only
4 - cyclone + front
5 - cyclone + thunderstorm
6 - front + thunderstorm
7 - cyclone + front + thunderstorm
The cyclones and fronts are identified using updated versions of the algorithms described in Catto and Dowdy (2021), specifically the front identification of Sansom and Catto (2023). The thunderstorm data is calculated using a proxy described in Dowdy (2022). See links to publications below.
The storm type data are on a 0.25 degree longitude-latitude grid between 20.75 and 69.25 degrees N and 45 degrees W to 45 degrees E, every 6 hours.
This dataset was produced under Natural Environment Research Council (NERC) project 'STORMY-WEATHER: Plausible storm hazards in a future climate' (grant reference: NE/V004166/1).
