Possible signal of tropospheric circulation patterns in middle atmosphere dynamics, Collm (51.3°N, 13°E) mesosphere lower thermosphere winds: 1979 - 2008
Time series of monthly mean Collm mesosphere/lower thermosphere winds 1979 - 2008 are analyses with respect to a possible correlation with North Atlantic Oscillation (NAO) and Southern Oscillation (SO) indices. There is a positive correlation with both indices until the middle 1990s, but later the c...
