Abstract: The causes of the appearance of a tail in the power spectrum of a gravity wave train in a shearing background terminating under the Hodges condition are studied. The power spectrum of this train for a wavenumber greater ...

Abstract: The dependence on liquid water content (LWC) and temperature (T) of the charge transfer, and in particular its sign, during ice crystal?graupel collisions is a matter of controversy. Some of the laboratory measurements do ...

Abstract: Charge transfer between colliding ice particles is measured using a wind tunnel inside a cold room. A cylinder growing by riming in a wind tunnel was used as a target for collisions between 5 and 6 m s?1 with ice spheres ...
