    • The global atmospheric energy transport analysed by a wavelength-based scale separation 

      Stoll, Johannes Patrick; Grand Graversen, Rune; Messori, Gabriele (Journal article; Tidsskriftartikkel; Peer reviewed, 2022)
      The global atmospheric circulation is fundamental for the local weather and climate by redistributing energy and moisture. To the present day, there is a knowledge gap at which spatial scales the energy and its components are transported. Therefore, we separate the meridional atmospheric energy transport in the ERA5 reanalysis by the spatial scales, the quasi-stationary and transient flow patterns, ...

    • Meridional-energy-transport extremes and the general circulation of Northern Hemisphere mid-latitudes: dominant weather regimes and preferred zonal wavenumbers 

      Lembo, Valerio; Fabiano, Federico; Galfi, Vera Melinda; Grand Graversen, Rune; Lucarini, Valerio; Messori, Gabriele (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-07)
      The extratropical meridional energy transport in the atmosphere is fundamentally intermittent in nature, having extremes large enough to affect the net seasonal transport. Here, we investigate how these extreme transports are associated with the dynamics of the atmosphere at multiple spatial scales, from planetary to synoptic. We use the ERA5 reanalysis data to perform a wavenumber decomposition ...
