Radar and snow

Published: 22 February 2021

Weather radar data offers high spatial and temporal structures of three dimensional precipitation fields and can be well used for warning and nowcasting of adverse winter weather. Radar reflectivity, Doppler velocity products and polarized radar moments de liver insights into cloud microphysics and dynamical properties, such as the discrimination between different types of hydrometeors, quantitative precipitation estimation, icing conditions or areas of strong shear. Beside aeronautical nowcasting application, also the limitations of using weather radar in a cold winter weather environment will be addressed.
