用连续云顶影像估计热带气旋海面风场

静止气象卫星能够持续观察台风云顶，却无法直接看到海面的风速。合成孔径雷达可以提供分辨率较高的表面风速测量，但覆盖范围与观测时刻有限，数据也难以实时连续取得。研究团队尝试用神经网络把静止卫星影像转换成二维近地面风场，同时从同一套内部表示中估计描述整个风暴强度的指标。 Simon Donike等人的这项研究收录在11月6日更新的计算机科学预印本列表中。

研究者通过逐项改变模型任务来比较效果。结果表明，把整幅风场和风暴尺度指标一起训练，对识别最大风速及其所在半径有帮助，在气旋快速增强的情形中尤其值得关注。研究用途是用高频次云顶观测补充稀疏的海面测量。最大风速有多强以及最强风带在哪里，是两项不同的输出。公开摘要没有给出可直接用于业务预警的误差阈值。
