THE METEOROLOGICAL CONDITIONS FOR DYNAMIC SOARING IN THE JETSTREAM AND IN THE LOW-LEVEL JET

Abstract

For static soaring all sources of energy have now been utilized. By means of topographical winds, thermal-convection and mountain waves results have been achieved which never could have been dreamed of at the beginning of rnotorless flying. Dynamic soaring, however, on which soaring pioneers had pinned so much hope, still represents an unsolved problem.
