Intercomparison of the northern hemisphere winter mid-latitude atmospheric variability of the IPCC models
Valerio Lucarini, Sandro Calmanti, Alessandro Dell'Aquila +2
We compare, for the overlapping time frame 1962-2000, the estimate of the northern hemisphere (NH) mid-latitude winter atmospheric variability within the XX century simulations of…
Discrepancies in Southern Hemisphere Mid-latitude Atmospheric Variability of the NCEP-NCAR and ECMWF Reanalyses
A. Dell'Aquila, P. M. Ruti, S. Calmanti +1
In this study we compare the representation of the southern hemisphere midlatitude winter variability in the NCEP-NCAR and ERA40 reanalyses. We use the classical Hayashi spectral t…
Does the subtropical jet catalyze the mid-latitude atmospheric regimes?
Paolo M. Ruti, Valerio Lucarini, Alessandro Dell'Aquila +2
Understanding the atmospheric low-frequency variability is of crucial importance in fields such as climate studies, climate change detection, and extended-range weather forecast. T…
Hayashi Spectra of the Northern Hemisphere Mid-latitude Atmospheric Variability in the NCEP and ERA 40 Reanalyses
Alessandro Dell'Aquila, Valerio Lucarini, Paolo Ruti +1
We compare 45 years of the reanalyses of NCEP-NCAR and ECMWF in terms of their representation of the mid-latitude winter atmospheric variability for the overlapping time frame 1957…
Destabilization of the thermohaline circulation by transient perturbations to the hydrological cycle
Valerio Lucarini, Sandro Calmanti, Vincenzo Artale
We reconsider the problem of the stability of the thermohaline circulation as described by a two-dimensional Boussinesq model with mixed boundary conditions. We determine how the s…
