Abstract

This study investigates low-frequency, unstable planetary waves in realistic basic states of January 1979, using three-dimensional spectral primitive equations derived by orthonormal vertical structure functions and Hough harmonics. Three selected unsable modes are extensively examined. One is the Green mode in the planetary waves, and the other two are deep Charney modes having different meridional structures. The results suggest that large-scale Pacific blocking during the winter are, at least in part, related to the low-frequency Charney mode having a dipole structure
