Investigation of horizontal drifts in the e region of the ionosphere in relation to random fading of radio waves

Regular determinations of E region wind velocities (V) and frequency of fading (N) were made from simultaneous fading records at three spaced receivers taken on two pulsed radio frequencies, 2.3 and 2.8 Mc/s respectively, between December 1954 and March 1955. A linear relation between V and N was obtained for each wavelength, and the experimental relation V = 1.86 N ¿ deduced. This result agrees with theory and the significance of the constant of proportionality is discussed.
