Abstract
The intermediate layer (or M layer) was detected at the height of 150-170 km in the nighttime ionospheric electron density profile measured by impedance probe on board the S-310-3 sounding rocket. This M layer was interpreted to be generated by the convergence effect of the ionization due to the west-east component of the solar tidal wind as suggested by K.Fujitaka. The altitude variation of the M layer during the course of a night is studied at three other locations with different latitudes. At Boulder (40/sup 0/N, 105/sup 0/W) and Wallops Island (38/sup 0/N, 75/sup 0/W) which have higher latitude than that of KSC(31/sup 0/N, 131/sup 0/E), the altitude of the observed M layers seems to be determined by the north-south component of the wind above about 150 km, by the west-east component of the wind below about 130 km in agreement with the drift theory. The altitude of the observed M layers at Arecibo (19/sup 0/N, 67/sup 0/W) located at lower latitude than that of KSC also coincides with the theoretical estimate when the direction of the north-south wind is assumed to be opposite to that prevailing in middle latitudes. Thus, M layer observations at these stations are consistent with
