- Аннотация: During appearance of noctilucent clouds on 12 August 2016 variations of the reflected ordinary wave amplitude at the frequency of 2.66 MHz of the partial reflection radar located at the Tumanny observatory (69.07ºN, 35.73ºE) were considered. The noctilucent clouds has been registered by the all sky camera in the Lovozero observatory (67.98ºN, 35.08ºE) with the time resolution of 30 s. They stretched from the northern to the southern horizon, moved in the southern direction, had wavy structures with the periods from 15 to 100. During the presence of the noctilucent clouds over the radar the Polar Mesospheric Summer Echoes at the heights of 83-86 km were noted. Detailed analysis has revealed that for the Polar Mesospheric Summer Echoes appearance is not enough only existence of noctilucent clouds over the antenna, also heterogeneity of the noctilucent clouds is required. Polar Mesospheric Summer Echoes heights decreased with speeds of 0.5 and 1.3 m/s.
