Space-time spectra of Northern Hemispheric Rossby waves during extended winter
https://doi.org/10.57804/w9cn-8z78
Data contains daily Rossby wave spectra that were obtained from a double Fourier transform, in space and time, and displayed in harmonics with wavenumber n and phase speed c. The underlying dataset for the space-time Fourier analysis is meridional wind of ERA5.
For further details about data, see section 2.2 in Schutte et al., 2024 (https://doi.org/10.5194/egusphere-2023-1877Opens in a new tab).
Data is split into two files:
1. allyears_NDJFM_35_75_spectra_v250hPa_61d.nc - spectra averaged between 35◦N-75◦N for the troposphere (250 hPa) and,
2. allyears_NDJFM_45_75_spectra_v10hPa_61d.nc - spectra averaged between 45◦N-75◦N in the stratosphere (10 hPa).
The files contain data for November to March (NDJFM) for years 1979 to 2021.

Geographic description:
The Rossby wave spectra were computed for the Northern Hemisphere between 35°N and 75°N (250 hPa), as well as 45°N and 75°N (10 hPa).
