Short summary
We introduce a diagnostic tool to assess in a climatological framework the optimal propagation conditions for stationary planetary waves. Analyzing 50 winters using NCEP/NCAR reanalysis data we demonstrate several problematic features of the refractive index of Rossby waves. We introduced the Rossby waves membership value function to calculate the optimal propagation conditions for Rossby waves. Sensitivity of our diagnostic tool to strong and weak vortex regimes are examined.
