中文摘要
拟议的研究旨在开发一种船载天气雷达,用于海上实地研究。 该雷达将大大提高我们对海洋天气系统的认识,这是陆基天气雷达无法达到的。 从这一仪器中获得的知识将提高我们对这些海洋天气系统中的降雨与陆地降雨有何不同的理解。 这些测量将反过来提高我们对海洋降水天气系统的物理学和动力学的认识。 从这些测量中获得的知识可能会改进我们在天气模型中计算世界广阔海洋降雨量的方法。 虽然没有部署在海上进行各种实地研究,但该雷达将为对雷达气象学最新技术感兴趣的学生和教师提供教学和学习平台。 这种船载C波段偏振多普勒雷达将提供目前美国不存在的海洋能力。陆地与海洋降水过程的差异已得到充分理解,但我们对这些过程的详细了解仍存在差距。 这些差异往往是不同的气溶胶浓度和陆地表面的差异加热的函数,导致陆地上的垂直运动比海洋更强。 该雷达将利用Ship-CPOL雷达的双极化测量能力,通过更好地估计降水和微物理参数表征,帮助填补这些空白。 这些数据还将作为目前用于估计世界各大洋降水量的各种卫星遥感技术的地面实况。
英文摘要
The proposed research seeks to develop a ship-based weather radar for use in field studies at sea. This radar will greatly improve our knowledge of oceanic weather systems, far from the reach of land-based weather radars. The knowledge gained from this instrument will improve our understanding of how rainfall in these oceanic weather systems differs from rainfall over land. These measurements will in turn improve our knowledge of the physics and dynamics of ocean-based precipitating weather systems. The knowledge gained from these measurements may improve our methods to calculate rainfall over the vast oceans of the world in weather models. While not deployed at sea on various field studies, this radar will serve as a teaching and learning platform for students and faculty interested in the latest techniques in radar meteorology. This ship-based C-band, polarimetric Doppler radar will provide an oceanic capability that currently does not exist in the U.S. Differences in precipitation processes over land versus sea are well understood but gaps still exist in our detailed knowledge of these processes. These differences are often a function of varying aerosol concentrations and differential heating of land surfaces leading to stronger vertical motions over land versus the sea. This radar will help fill those gaps through better precipitation estimation and microphysical parameter characterization using the dual-polarization measurement capability from the Ship-CPOL radar. These data will also serve as ground truth for various satellite remote sensing techniques used today to estimate precipitation over the vast oceans of the world.
