Time scales (a) τCK, (b) τCP, and (c) τdry (days) with which horizontally integrated energy (KE for τCK, APE for τCP, and KE + APE for τdry) could be replenished through (a) barotropic energy conversion CK, (b) baroclinic energy conversion CP, and (c) their sum CK + CP when the anomaly pattern shown in Fig. 2 is shifted zonally and then meridionally. Evaluation of KE and APE is based on the original, nonshifted composite and integrated over the entire Northern Hemisphere, whereas CK and CP are integrated over [0°–60°N, 100°–150°E] for the nonshifted composite or the domain shifted with the anomaly pattern. All the energy and conversions are integrated from the surface to the 100-hPa level before integrated horizontally, but τCK evaluated solely at the 850-hPa level is also shown in right half of each of the cells in (a). Time scales (a),(c) <30 and (b) <15 days are highlighted with boldface.
