Abstract : In forecasting the motion of amorphous precipitation echo fields, it is demonstrated that the doubled average velocity of the centroid of such fields may be useful in extrapolating the echo for very short range automated forecasts. However, an increase in forecast accuracy results by substituting the echo element velocity for that of the centroid. (Author)
