IACDC Mediterranean Cyclones and Tracks Database

The IACDC’s Cyclones and Cyclone Tracks Database is a publicly open database created specifically for the IACDC.

The database includes all the cyclones identified for 1980-2016, along with some key parameters for each, and cyclone tracks which follows the path of the ones previously identified. Making the database particularly useful to anyone studying cyclones and their tracks in the Mediterranean and surrounding region.

The database has been created using an algorithm, finetuned for cyclones in the Mediterranean. The method was first developed for the identification of parent-daughter cyclone relations in the Mediterranean, and the results published by Ziv et al. (2015). It was later used as a basis for the classification of daughter cyclone formations with respect to the parent’s frontal system by Saaroni et al. (2016).

The database was created using data from the ERA Interim reanalysis for 1980 to 2016, with a temporal resolution of 6 hours and a spatial resolution 0.75˚x0.75˚. The region covered in the database is 5˚N-75˚N, 25˚W-65˚E; so although the algorithm is fine tuned to cyclones in the Mediterranean basin, neighbouring cyclones are also recorded.

The Cyclone and Tracks database has been split into two datasets:

  • Tracks database
    • A unique track ID for each
    • The track length (number of counts of cyclone centres, i.e. units of 6 hours)
    • List of cyclones contributing to each track
  • Cyclones database
    • A unique cyclone ID
    • Time at which cyclone was detected
    • Latitude and longitude
    • Sea level pressure (SLP) at low centre
    • SLP gradient
    • Cyclone radius
    • Geopotential thickness between the 500-1000hPa and 500-850hPa pressure levels
    • Steering U wind and V wind at 500hPa
    • Predicted location of cyclone centre 3 hours before detection
    • Predicted location of cyclone centre 6 hours after detection
