基于JUNO卫星WAVES仪器波动数据的木星磁层哨声波分析研究
木星磁层 JUNO卫星 哨声波 统计分析
2019/3/19
等离子体波的空间分布在木星磁层高能电子动力学过程中起着重要的作用.现有大多数对木星磁层哨声波的观测仅限于|λ|≤ 15°的磁纬范围内，但是最新的JUNO卫星WAVES仪器提供的波动数据使得更高纬度、更广区域范围内的等离子体波动分布研究成为可能.本文通过对JUNO卫星WAVES仪器数据进行分析处理，详细研究了木星磁层哨声波的空间分布特性.观测表明，存在位于高LJ、高磁纬的木星磁层哨声波，它们广泛分布...

2015/9/17
The very strong volcanic eruption of Mt. Pinatubo in June 1991 directly affected the troposphere and lower and middle stratosphere. Here we look at its effects in the mesopause region as revealed by t...
The polarization method for recognition of seismomagnetic waves against a noise background is presented. The method is applied to detection of magnetic oscillations accompanying the propagation of sur...

Sea level oscillations are the superposition of many contributions, among which the main are astronomic and meteorological low-frequency tides. In Ligurian Sea meteo-tide components, being most ample ...
T waves in Western Mediterranean Sea after the May 21, 2003 Algerian earthquake
T waves Ligurian Sea SOFAR frequency content
2015/9/2
Aim of this paper is to discuss on the T phases generated after the mb 6.5 earthquake that shook Algeria on May 21,
2003. The seismograms, recorded by a cluster of seismic stations located on the coa...
The Rayleigh equation has real coefficients; therefore, also the case of complex conjugated roots may be explained physically. The Author proves that the Somigliana waves may be formed for Poisson rat...
