| Research Abstract |
Using two polarimetric radars and the hydrometeor videosonde, we performed an observation of snow clouds in an inland region of eastern Hokkaido for the period from February to March 2011. During the observation period, many different types of snow clouds associated with cyclones and the winter monsoon wind were observed. The polarimetric radar observation showed kinematic and microphysical structures and the direct observation using the videosonde revealed size, type, number density and size distribution of cloud ice. According to the observation, size distribution of cloud ice was formulated and its sedimentation process was installed into the cloud-resolving model.
