Abstract: Case histories of six microseism storms generated by marine cold fronts are given. Seismograms from the New York City and Palisades stations of Columbia University and from Weston College Observatory were utilized together ...

Abstract: Nearly all the microseism storms generated by extra-tropical cyclones in the western North Atlantic during the fall and winter seasons of 1948?49 and 1949?50 have been studied, together with some storms that occurred during ...

Abstract: This is a further study of the use of natural infrasound in the atmosphere to monitor tidal circulation in the lower thermosphere. The height of this circulation is determined with the use of a reference atmospheric model, ...

Abstract: The relatively low frequency of the sonic boom generated by the Concorde SST permits propagation in the form of infrasound to long range with small attenuation. Signal characteristics at long range are a function of ...

Abstract: Atmospheric waves from the Soviet nuclear test of 30 October 1961 axe described for nine stations having wide global distribution. The records are characterized by waves which begin with the highest amplitudes and which ...

Abstract: Relations between the behavior of atmospheric gravity waves and the meteorological conditions during the approach of coastal cyclones at Palisades, New York (near New York City) are investigated. It is shown that the ...

Abstract: In a continuing study of the feasibility of using microbarom (natural infrasound) observations to define characteristics of upper air winds, we determined the seasonal mean trace velocity of microbaroms. We show that this ...

Abstract: An IGY tsunami recorder at Texas Tower No. 4 off New York has detected ocean waves of periods from 4 to 10 min which have amplitudes up to 100 times greater than atmospheric pressure oscillations which occurred simultaneously. ...

Abstract: Rocketsonde observations and infrasound results are used to investigate the variability of the summer stratopause region during one month in summer. It is found that fluctuations of 2?3 days and about 16-day periods are ...
