In the F region this latitude variation persists throughout the light due to the action of upper atmospheric wind currents from day-side to night-side hemispheres.
MODELS OF PERIODIC OSCILLATIONS OF POLAR MOTION AND LATITUDE VARIATIONS.
The latitude variations are dominated by the polar motion, presented by polar motion projection onto the corresponding meridian plane.
The latitude variations in the zero meridian are simulated by the same time series of polar motion plus a model of normally distributed random errors N(0, 0.
SIMULATED JUMPS OF POLAR MOTION AND LATITUDE VARIATIONS.
The model of simulated jumps of the polar motion and latitude variations consists of 4 jumps in the periods of minimal beating.
The integrated time series of polar motion and latitude variations after removing the global trend, are shown in Figure 8.
Berge says this is "the first radio map of Saturn that shows detailed latitude variations.
