Radial velocity data from two or more Doppler weather radars are commonly combined to obtain the vector or true velocity of winds at a given location. This work proposes a novel scheme for combining scalar and vector data from multiple radars. The number of overlapping radars at a point is automatically determined. The data combining algorithm (2-D, 3-D, or least-squares) is automatically determined from the number of overlapping radars. The use of latitude-longitude grid results in a universal grid presentation. A variable (user-definable) box-averaging method of vector representation is adopted and vector fields are depicted as fields of arrows. A novel method is adopted for handling boxes lying on boundaries of overlapping radar zones.
