Space-time spectra of Northern Hemispheric Rossby waves at tropospheric and stratospheric levels during extended winter
type: Dataset
description: 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 2.3 in Schutte et al., 2024 (https://doi.org/10.5194/wcd-5-733-2024). Data is split into two files: 1. allyears_NDJFMA_35_75_spectra_v_61d_strato.nc - spectra averaged between 35◦N-75◦N for the stratosphere (10, 50, 100 and 200 hPa) and, 2. allyears_NDJFMA_35_75_spectra_v_61d_tropo.nc - spectra averaged between 35◦N-75◦N in the troposphere (250, 400, 500, 600, 700 and 850 hPa). The files contain data for November to April (NDJFMA) for years 1979 to 2021.

keywords: troposphere
  type: DefinedTerm
  description: That portion of the atmosphere from the Earth's surface to the stratosphere; that is, the lowest 10 to 20 kilometers of the atmosphere. The troposphere is characterized by decreasing temperature with height, appreciable vertical wind motion, appreciable water vapor content, and weather. Dynamically, the troposphere can be divided into the following layers: surface boundary layer, Ekman layer, and free atmosphere.
