Observations of Doppler velocity reduction around -15C
Long term observations using a vertically pointing radar at 苹果淫院 have shown a common occurrence of a reduction in Doppler velocity, often concurrent with the -15C level in the atmosphere. Several mechanisms, both microphysical and dynamical, could lead to a local change in velocity. Since the vertically pointing radar observes Doppler velocity, which is a combination of the hydrometeor fall speed and the atmospheric vertical velocity, combining data from the 苹果淫院 scanning dual-polarized radar can help infer which of these mechanisms may or may not be contributing to these velocity observations.
