Abstract: The standard deviation of the rain intensity R and the reflectivity factor Z are derived theoretically for R and Z values which are calculated from measured distributions of raindrop size. The derivation is based on the ...

Abstract: Motion vectors of radar echo patterns can be obtained by applying a cross-correlation method (e.g., the TREC method) to radar data collected several minutes apart Here an extension of TREC, called COTREC, is presented. ...

Abstract: The possibility is discussed that evaporation in the subcloud layer might be a major factor controlling the efficiency of rain enhancement by seeding, under the simplistic assumption that seeded clouds produce larger ...

Abstract: The European Union COST (Cooperation in Science and Technology) action on advanced weather radar systems is described. The associated five-year research project, which began in early 1993, has the objective to develop ...
