Abstract: Many snowflakes in various melting stages were directly sampled at the, ground in almost the same way as described by Knight. From these observations the degrees of melting of snowflakes are classified into five stages. ...

Abstract: Types, degree of riming and size of snow particles comprising aggregates from snow bands were investigated. From the data obtained, the microphysical processes which control the precipitation intensity were elucidated. The ...

Abstract: n extremely long ice pellet event with extensive episodic ice pellet falls occurred over northern Japan on 10 April 2005. The synoptic-scale environmental features of this event were examined based on Japan Meteorological ...

Abstract: his paper describes a numerical and observational study focused on ice-pellet formation and microphysical properties near 0°C from an ice-pellet-dominated storm associated with an unusually warm and dry atmosphere on 10 ...

Abstract: This article presents a detailed analysis of a meso-?-scale (?17 km wavelength) shear instability wave along a snowband using a series of dual-Doppler radar data. The wave developed along a low-level shear line that formed ...

Abstract: A stochastic microphysical model of snow aggregation that combines a simple aggregation model with a Monte Carlo method was developed. Explicit treatment of the shape of individual snowflakes in the new model facilitates ...

Abstract: We present three-dimensional (3D) displays of meteorological radar echoes. We made surfaces of precipitating clouds specified by some echo intensity (dBZ) by the marching cubes method, which is a high-resolution 3D surface ...

Abstract: Observations of snowstorms were carried out around Ishikari Bay, Hokkaido, Japan, from December 1991 to February 1992. On 15 January 1992, a longitudinal-mode snowband was observed by a dual-Doppler radar system. The ...
