A lowpass filter of 15-days is applied and the daily climatology (also lowpass filtered) subtracted. The method of Zimin et al. 2003 with a latitude dependent wavenumber range is then applied. The description of this method and the discussion about the climatology of quasi-stationary waves (this dataset) and their connection to European temperature anomalies and extreme events can be found in the attached methodology statement.","keywords":"","inputDescription":null,"outputDescription":null,"softwareReference":null,"identifier_set":[]}
