Web終了ページ: 239. 抄録: This paper describes the results of meteor radar observations which have been carried out at Kyoto University since December, 1977. The radar, a coherent pulse doppler radar with a transmitting frequency of 31.57 MHz and a nominal peak power of 10 kW, is able to detect wind fields at meteor regions of 80-110 km. WebThis paper briefly reviews ionospheric irregularities that occur in the E and F regions at mid-latitudes. Sporadic E (E S ) is a common ionospheric irregularity phenomenon that is first noticed in the E layer. E S mainly appears during daytime in summer hemispheres, and is formed primarily from neutral wind shear in the mesosphere and lower thermosphere …
