The behavior of extensive air showers was investigated in the upper half of the atmosphere. The zenith angle distribution of air showers with particle density more than 20 m/sup -2/ was observed by a Fukui-Miyamoto discharge chamber at 8500 m above sea level. The observed result agrees with the altitude variation of shower intensity, and shows that the intensity maximum of vertical alr showers is at the depth of 500--550 g cm/sup -2/ of air. The lateral distribution of shower particles was measured by scintillator arrays at 7000 m above sea level. The average behavior of lateral distribution of the shower of size around 10/sup 5/ at this altitude observed within the distance of 0.1 Moliere unit from the core is approximately given by f(r) approximates r/sup -n/ ; r in Moliere unit with, on the average, n approximates 1.3, but n of each shower fluctuates between 1.0 and 1.5. The intensity variation with altitude of air shower was calculated, using the shower curve theoretically obtained by Ueda and Ogita, and compared with experiment. (auth)
