The gridded weather typing classification (GWTC) system is a geographically- and seasonally-relative classification of multivariate surface weather conditions (weather types) for North America. Using six near-surface weather variables (temperature, dew point, sea-level pressure, cloudiness, wind speed, and wind direction) from the North American Regional Reanalysis (NARR; Mesinger et al., 2006), the GWTC classifies every day since 1979 into one of 11 different weather types at over 9000 locations. While the 9 'core weather types' mostly relate to different temperature and humidity conditions, the two transitional weather types identify the passage of traditional cold fronts and warm fronts. The GWTC-2 is a global-scale edition of the original GWTC, with some minor differences, and can be found here.
