    • Sudden Stratospheric Warming Compendium

    Metadata Updated: September 19, 2023

    Sudden Stratospheric Warming Compendium (SSWC) data set documents the stratospheric, tropospheric, and surface climate impacts of sudden stratospheric warmings. This examines major mid-winter warmings, as defined by a reversal between November-March of the zonal winds at 10 hPa and 60N from westerly to easterly. The one major warming that occurred in the Southern Hemisphere is also included. Analyses are available from 6 different reanalyses: MERRA2 (1980-2014), JRA-55 (1958-2014), ERA-interim (1979-2014), ERA-40 (1958-2002), NOAA20CR (1958-2011), and NCEP-NCAR I (1958-2014). Global gridded anomaly fields are calculated from smoothed daily climatologies based on the full record of each reanalysis. Data is provided 60 days prior to and after each SSW event. Pressure-level fields include winds, temperatures, geopotential heights, vorticity and potential vorticity, and ozone; surface fields include temperatures, sea-level pressures, and precipitation. Other derived data and climate indices are also included. Data are provided as daily means, with 2.5x2.5 degree horizontal resolution for pressure-level fields and native horizontal resolution for surface fields. Daily climatological means and standard deviations of all input fields are included with the output.

    Lineage Data in the compendium originated from various output reanalysis datasets which are commonly available. These reanalysis data, which are given on a variety of vertical, horizontal, and temporal resolutions, are converted to 1) daily pressure-level data on a 2.5x2.5 degree horizontal grid and 2) daily surface data on the native horizontal grid. Daily climatologies are calculated from these processed full-field data and anomaly fields are calculated. Event dates are selected and the processed full-field and anomaly reanalysis data are extracted. A number of output data fields are calculated using these extracted full-field and anomaly data.
