ResumoThe present paper deals with a study of the dimensions of precipitation areas as they appear on the radar scopes. Measurements of the vertical thickness and the horizontal diameter of these areas are made for both cold- and warm-frontal weather situations. It is found that echoes associated with cold fronts are taller in vertical extent and smaller horizontally than echoes associated with warm fronts. There is a small seasonal variation. Echo dimensions are also compared with the stability of the air. As the air becomes more unstable the precipitation echoes become larger both vertically and horizontally.
