Opportunities of radar tracking way towards research of breeze and mountain-valley air circulation influence on diurnal bird migration

Abstract

The results of observations over the storks flight let us assume that the flock chooses the path and flight altitude instinctively, by means of vertical streams search, using their own bodies and wings, looking for minimum energy it can spend due to atmosphere conditions. It’s not occasionally that the flight path of the stork is similar to the straight line only on separate parts. The path is sometimes branched and its structure is changed very rapidly under the influence of convective streams and stripes formed due to coastal breeze and mountain-valley circulation process taking place on concrete day in concrete region. One can solve the reverse task en route using the storks’ flight peculiarities for the vertical streams structure determination. The structure of flight path is depends upon the structure of vertical streams movement in surface air layer.
