Analysis of a vast series of angel echo observations made by a millimetric vertically-pointing radar reveals four major types of echo organization on height-time recordings. The relationship between the formation and development of these structures and the thermodynamic state of the atmosphere is clarified. The meteorological indicator role played by angel echoes is then discussed. In particular it is shown that in certain conditions, angel echoes can delineate the boundaries of small cumulus.
