ジャーナル フリーRemarkable progress has been made in our understanding of thermospheric waves, acoustic gravity waves and tidal waves. But our knowledge about planetary wave is still meager. The situation is much dependent upon observation; the measurement by meteor wind and incoherent scatter radars of gravity wave and tidal wave being especially precise. Comparative studies among different experiments are now found successful. Incoherent scatter radars are proved to be of vital importance for precise and continuous measurement of the motion of both middle (neutral) atmosphere and upper (plasma) atmosphere. A breakthrough in theoretical study can be expected by powerful experiments in the near future.抄録全体を表示PDF形式でダウンロード (1618K) -

ジャーナル フリーThe atomic oxygen 6300Å emission in the airglow was observed in Logan, Utah during the period from September, 1970 to April, 1971. The emission rate of the morning twilight is found to be correlated with the thermospheric temperature which is derived by using the flux of the solar 10.7cm radio wave and the geomagnetic disturbance index, Kp. There are considerable fluctuations in the emission rate which are not correlated with either the solar or geomagnetic disturbances.抄録全体を表示PDF形式でダウンロード (1059K) -

ジャーナル フリーThe Phoenix lineations are a set of east-west trending magnetic anomalies that recorded sea-Boor spreading in the Nauru and Central Pacific Basins of the western Pacific from the Late Jurassic through the Early Cretaceous. The northern portions of these basins near the Marshall-Gilbert Islands are characterized by a magnetic quiet zone that presumably formed in the Late Jurassic prior to M25 (153m. y.). In the eastern part of the Central Pacific Basin just east of Magellan Rise is a northwest trending M11 (126m. y.) to M4 (117m. y.) anomaly sequence. The geometry and spreading rates associated with the east-west trending Phoenix lineations and the Hawaiian lineations to the north suggest that the two patterns met at a fault-fault-ridge triple junction from M25 (153m. y.) until M14 (131m. y.) time. This system underwent a readjustment between M14 and M10 time that transferred the Magellan Rise from the Phoenix plate to the Pacific plate and established two triple junctions in place of the previous one. A stable fault-fault-ridge junction formed just southeast of Magellan Rise to connect the east-west and northwest trending Phoenix lineations, while a slow-spreading, ridge-ridge-ridge junction broke the original Pacific plate in two from at least M11 to M4 time and was responsible for the formation of the Mid-Pacific Mountains.抄録全体を表示PDF形式でダウンロード (2024K) -
