Abstract:

Anomalous clear atmosphere returns of X-Band vertically pointing radar signals observed at Fort Huachuca, Arizona, during September - October 1964, are examined in conjunction with analysis of low level atmospheric convection. It is concluded that the radar echoes, commonly termed dot angels were produced by sharp gradients in refractive index across the boundary surfaces of convective air parcels. Author
