Zusammenfassung: | This dataset comprises 12 hourly data of the envelope field of Northern hemispheric upper tropospheric (300 hPa) quasi-stationary waves calculated between1979-06-01 and 2015-08-31. The data were derived as part of the NERC funded ODYSEA project (Ocean Dynamics as Driver of Seasonal to Decadal European Atmospheric variability).
The envelope field in this dataset is a phase-independent measure of the wave amplitude and is derived from the meridional wind at 300 hPa of the ERA-Interim reanalysis data. To remove the faster transient signals a 15-day lowpass filter was applied to the meridional wind and then subtracted from a daily climatology. The envelope field allows for the identification of a slowly evolving stationary or slowly moving wave packet.
Full details of the method are described in the methodology statement that can be found in the docs section. |
