To examine the mutual influence between high-frequency and low-frequency transient and stationary eddies, the characteristics of Northern Hemisphere atmospheric blocking events are evaluated. The spatial and temporal characteristics of atmospheric blocking are compared between NCEP/NCAR reanalysis and the two simulations. The blocking spatial distribution indicates a more accurate blocking representation in 1/4 degree resolution simulation over western North America, and a more realistic characteristic timescale of the phenomenon. The case composite and the wave activity analysis suggest a distinct eddy-mean flow interaction characteristic over North Pacific and North Atlantic.
