| Research Abstract |
A stratiformed precipitating system associated with an extratropical cyclone off the south coast of Japan in winter season often brings rainfall or snowfall to areas along Pacific Ocean of Japan. In this study, the structure of the stratiformed precipitating system and the meteorological conditions with rainfall or snowfall brought by the precipitating system were analyzed. Then, the probability of determination of rain or snow in the stratiformed precipitating system was discussed.
The three-dimensional observations of the height of melting layer and the falling to surface of the layer with snowflakes and ice particles above the brightband by X-band multi-parameter radars are expected to determine rainfall or snowfall in the stratiformed precipitating system adequately. Additionally, it is also necessary to observe a circulation at the lower layer of the extratropical cyclone and meteorological conditions just before the arriving of the stratiformed precipitating system.
