ANGELS IN FOCUS.
Abstract
Recent independent observations of 'dot' angel echoes are drawn together to provide a coherent picture of their physical structure. The 'dot' or 'poing' angel is a transitory echo associated with an invisible atmospheric target passing through a fixed radar beam whose duration generally corresponds to the time of transport of a point source across the beam with the wind speed. The observations are shown to be consistent with specular reflections from the hemispherical, concave-downward cap of a rising thermal or convective bubble. (Author)
