Name

CEOS/NSIDC Extratropical Cyclone Tracking (CNECT) Algorithm

Description

This algorithm has two steps: 1) detection of cyclone centers and areas and 2) tracking of those features. Center detection is based on local minima in sea-level pressure (within a 200 km radius) that have a pressure gradient of at least 7.5 hPa/1000 km. The area of storms and presence of single- and multi-center cyclones are determined using last-closed isobars. Tracking is based on the nearest neighbor to a predicted cyclone propagation location. Cyclone size, intensity, propagation, and interactions (e.g., splitting and merging with other storms) are tabulated at each observation time.

Cyclone Parameters File

Description

This cyclone parameters file records the input parameters used for the cyclone detection and tracking code to produce the files in this database. It can be opened using pandas in Python via pandas.read_pickle($FILEPATH$), where $FILEPATH$ is the path to where this file is stored on your computer.

Northern Hemisphere Extratropical Cyclone Tracks from ERA5: 1940-1949

Description

Folder containing CSV files that describe extratropical cyclone tracks detected from the ERA5 atmospheric analysis using version 13.2 of the CEOS/NSIDC extratropical cyclone tracking algorithm (as described in Crawford et al., 2021; https://doi.org/10.1175/MWR-D-20-0417.1). Storms are detected with a 3-h temporal resolution and 25-km spatial resolution for the period 1940-1949. All storms whose ending time (cyclolysis) occurs in the same month are grouped into a single CSV file and can be identified by their unique system number (sid). The monthly files are organized within folders for each year. See accompanying metadata file for more details (e.g., descriptions and units for each column). This algorithm explicitly tracks each center of a multi-center cyclones, but in this database, each multi-center cyclone is represented only by its primary center -- i.e., the entire storm system is being represented by the location and area. Only storm systems that meet the following four criteria are included: lifespan of at least 24 hours, track length of at least 1000 km, observed at least once over an elevation less than 500 m, and observed at least once at at a distance of at least 500 km from its origin point are included.
