Abstract: The melting layer in precipitation is physically modeled and compared with high resolution Doppler radar data. The model includes a new formulation of the dielectric properties and can handle all ice particles with densities ...

Abstract: Vertical air velocity in rain is calculated from the minima in the reflectivity profile of the Doppler velocity spectra between succeeding range cells. The reflectivity minimum is converted to air velocity, assuming a ...

Abstract: A new method is given to determine the rain intensity from data collected by a vertically scanning Doppler radar. The method is based an relating a theoretical velocity spectrum derived from a gamma drop size distribution ...

Abstract: Evapotranspiration is calculated from surface temperatures using an energy balance method. This method is sensitive to the temperature difference between the surface and the air above, and somewhat to the windspeed. In ...
