Radar Studies of Clouds and Precipitation

9407074斯利瓦斯塔瓦这项工作的目标是雨滴和云滴(大小)光谱的结构和演变。前者的特征，包括雨率和水分，将通过使用两个雷达的观测，以不同的频率传输，并评估衰减以“改善”后向散射反射率来探索。另一方面，将利用最近的数值结果来研究云滴光谱的特征，以改进现有的理论和使用甚高频雷达测量选定地点的液滴光谱。这两个主题都将有助于理解(液体)降水的物理学。

9407074 Srivastava The objectives of this work are the structure and evolution of the (size) spectra of both raindrops and cloud drops. Characteristics of the former, including rain rate and water content, will be explored using observations from two radars, transmitting at different frequencies, and evaluating the attenuation to "improve" the backscattered reflectivity. Characteristics of cloud drop spectra, on the other hand, will be investigated using recent numerical results to improve existing theory and the use of VHF radar to measure droplet spectra at selected sites. Both topics will help to understand the physics of (liquid) precipitation.
