 note = {S-310-3号機ロケットに搭載されたインピーダンスプローブによって夜間の電離層電子密度の高度分布が測定され,高度150km～170kmにM層が観測された.今回観測されたM層はFujitakaのモデル潮汐風の東西成分によって生成されたと考えられる.KSCでこれまでに観測されたM層の特性からKSCが潮汐風の南北成分の反転する緯度的境界地点に近いことが調べられた.BoulderとWallops島で観測されたM層は,150km以上では南北風によって生じ,130km以下では東西風によって生成されることがわかった.AreciboのM層がモデル南北風を反転させた風系によって生じていることから,低緯度では南北風の風向きが反転していることが明らかになった., 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°N, 105°W) and Wallops Island (38°N, 75°W) which have higher latitude than that of KSC (31°N, 131°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 thery. The altitude of the observed M layers at Arecibo (19°N, 67°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 the view that a round the latitude range of KSC the north-south wind reverses direction and the west-east component of the wind has the dominant effect on the formation of the M layer., 資料番号: SA0124768000},
