    "title": "Re-analysis ERA-20C European winter extra-tropical cyclone tracks 1900-2010",
    "abstract": "This dataset contains winter (October-March) extra-tropical cyclone tracks generated by TRACK (Hodges 1994, 1995, 1999) that pass through a Western European domain from the ERA-20C (1900-2010). The tracks were filtered to retain those that travelled 1000km and lasted 2 days. Fields referenced to the tracks are: mean sea-level pressure (min within 5 degrees), 925hPa windspeed (max within 6 degrees), precipitation (max within 5 degrees), 700hPa vertical velocity (min within 5 degrees), 925hPa land-windspeed (max within 6 degrees), precipitation (area average over 5 degrees).\r\n\r\nThis data was collected as part of Robust Spatial Projections for the Real World (Real Projections) NERC (Natural Environment Research Council) NE/N018486/1.\r\n\r\nFor files with the naming convention:\r\n\r\n[Dataset]_tr_trs_VOR850_[yearstart][yearend]_pos.addmslp_addspeed_addprecip_addomega_addlandwinds_addavgprecip.new_1000km2dayfiltered[_RealProjregion2filtered_maxlandwindsinregion].txt\r\n\r\n\r\nThe track files contain a 5 line header. The information in the body of the file gives:\r\n1. Date and time (YYYYMMDDHH).\r\n2. Longitude of relative vorticity maximum (degrees).\r\n3. Latitude of relative vorticity maximum (degrees).\r\n4. Relative vorticty at T42 resolution (x10-5 s-1).\r\n5. Longitude of associated MSLP minimum (degrees).\r\n6. Latitude of associated MSLP minimum (degrees).\r\n7. MSLP minimum (hPa).\r\n8. Longitude of 925hPa windspeed maximum within a 6 degree radius of vorticity maximum (degrees).\r\n9. Latitude of 925hPa windspeed maximum within a 6 degree radius of vorticity maximum (degrees).\r\n10. 925hPa windspeed maximum within a 6 degree radius of vorticity maximum (ms-1).\r\n11. Longitude of precipitation maximum within a 5 degree radius of vorticity maximum (degrees)\r\n12. Latitude of precipitation maximum within a 5 degree radius of vorticity maximum (degrees)\r\n13. Precipitation maximum within a 5 degree radius of vorticity maximum (mmhr-1)\r\n14. Longitude of 700hPa minimum vertical velocity within a 5 degree radius of vorticity maximum (degrees)\r\n15. Latitude of 700hPa minimum vertical velocity within a 5 degree radius of vorticity maximum (degrees)\r\n16. 700hPa vertical velocity minimum within a 5 degree radius of vorticity maximum (ms-1)\r\n17. Longitude of 925hPa windspeed maximum over European and Scandinavian land within a 6 degree radius of vorticity maximum (degrees).\r\n18. Latitude of 925hPa windspeed maximum over European and Scandinavian land within a 6 degree radius of vorticity maximum (degrees).\r\n19. 925hPa windspeed maximum over European and Scandinavian land within a 6 degree radius of vorticity maximum (ms-1).\r\n20. Precipitation area averaged over a 5 degree radius of vorticity maximum (mmhr-1)\r\n\r\nThe [_RealProjregion2filtered_maxlandwindsinregion] refers to data that has been filtered to those storms that have their maximum 925hPa windspeed over land in the region. The add[field] refers to which field, and the order, in which the meteorological fields have been referenced to the vorticity centres.\r\n\r\n\r\nFor files with the naming convention:\r\n\r\n[Dataset]_tr_trs_VOR850_[yearstart][yearend]_pos.addmslp_addspeed_addprecip_addomega_addlandwinds_addavgprecip_addmax5cmorph_addavg5cmorph.new_1000km2dayfiltered_RealProjregion2filtered_maxlandwindsinregion.txt\r\n\r\n(i.e. these include two additional fields for a smaller temporal range)\r\n\r\nThe same track information as above in included, plus:\r\n\r\n21.
