摘要
A daily measure of the strength of the ionospheric current system near noon for each day of 1985 has been determined from magnetometer records. These daily values are correlated with daily tidal amplitudes in the mesosphere observed by the spaced-antenna wind technique. If upward-propagating tidal modes play any part in inducing dynamo current some correlation would be expected, but none is found. Also, the day-to-day variations of the diurnal and semi-diurnal tides are uncorrelated with each other. Possible reasons for the results are discussed.
