Utilizing the daily analyzed zonal and meridional wind components at 200 mb for the year 1970 (available from the tropical analysis program of the National Meteorological Center) daily estimates of the meridional eddy momentum transfer have been computed at 33, 29, 24, 20, 15, 10, 5 and 0°N. The momentum transfers were then subjected to conventional spectrum analysis and the results indicate a coherent relationship from 33N into the subtropics at 14–16 and 4.35 days. This suggests a form of mid‐latitude tropical interaction that should be considered in investigation of tropical variations at these periods.
