| Summary: | 碩士 === 輔仁大學 === 物理學研究所 === 86 === The study tends to analyze geopotential which measured by radiosondes using the vertical phase and group velocities calculation methods within Taiwan area. There are oscillations phenomenon in 29. 5 day period from January 1996 to February 1998. We also noticed the phenomenon is caused by the interaction of gravity between the earth and moon. We named the phenomenon as lunar atmospheric tidal.
From the calculation of vertical group velocities, we find that the vertical group velocities is upward behind the troposphere; the direction of vertical group velocities below troposphere is downward. This shows us the energy of the waving should generate from stir up of atmosphere near troposphere. Furthermore through the characteristics of transmission of wave, we can understand more about mechanism of waves caused by lunar atmospheric tidal in lower atmosphere.
