| Popis: |
The radar reflectivity factor Z and the snowfall rate R were measured by a vertical pointing radar and a high sensitivity snow gauge, respectively. From these data we found a best fit Z-R relation for three snowfall events. The diameter and fall velocity of snow particles were also measured at the radar site by using a video camera and an image processor. The types of snow particles described in this paper are aggregates and graupel-like particles, which account for much of snowfall in Antarctica. The range of snowfall rate is similar in all three cases, while the radar reflectivity factor is much different. For the same radar reflectivity factor, the snowfall rate of graupel-like particles was about seven times as large as that for aggregates. |
