C-band Weather Radar (MR17-05C)

Low level clouds over the Arctic Ocean which usually dominate during summer have a key role for sea/ice surface heat budget. In addition, cyclones which modify the sea-ice distributions are substantially important to understand the air-ice-sea interaction. To capture the broad cloud-precipitation systems and their temporal and spatial evolution over the Arctic Ocean, three-dimensional radar echo structure and wind fields of rain/snow clouds was obtained by C-band Doppler radar observation.夏季在北冰洋上空占据主导地位的低层云，对海/冰表面的热量收支（heat budget）具有关键作用。此外，能够改变海冰分布的气旋，对于理解海-冰-气相互作用（air-ice-sea interaction）至关重要。为了捕捉北冰洋上空大范围的云-降水系统及其时空演变特征，研究人员通过C波段多普勒雷达（C-band Doppler radar）观测，获取了雨雪云的三维雷达回波结构与风场数据。
