A new quantity -maximum correlation time-is introduced to describe thephase relation between the daily variations of the vertical component of geomagnetic field at two stations. The maximum correlation time is computed by using adequate data processing technique from the hourly readings of vertical component at the Peking and Wuhan stations. The mean value of the maximum correlation time is shown to be nearly equal to the difference of local times for these stations. Moreover, it exhibits remarkable seasonal variation which has a period of one year and ranges to about 0.7 hour. Fourier analysis of the maximum correlation time shows that it also conta-ins two appreciable harmonics with periods 29.8 ± 0.6 and 13.7 ± 0.2 days respectively,, and with amplitudes of about 0.06 hour for both harmonics.

The phase relations between the daily variations of the geomagnetic field at Sheshan (佘山)amd Lunping (崙坪) Geomagnetic Observatories are described by using the concept of maximum correlation time. The data of the vertical component and the declination in 1974 were used, and the maximum entropy method (MEM) was applied to the results of the maximum correlation time series. It shows that there is a remarkable harmonic variation with a period of 14.6 days. This may be due to 'lunar ocean dynamo', as suggested by the author. When the lunar oceanic tide current flows along the East China Sea and the Taiwan Straits (a conducting channel), it will cause different magnetic fields, e.g. both in direction and in magnitude for Z, at the coastal stations located at both sides of the strait. Therefore the maximum correlation time presents the lunar semi-monthly variation.
