从空间站拍摄到的飓风弗莱迪

Cyclone Freddy is pictured northeast of the island nation of Mauritius from the International Space Station as it orbited 267 miles above the Indian Ocean on Feb. 20, 2023.

On the space station are two NASA-built weather instruments, the Compact Ocean Wind Vector Radiometer (COWVR) and the Temporal Experiment for Storms and Tropical Systems (TEMPEST), that track tropical cyclones like Freddy. Launched in late 2021 to the space station, COWVR measures the speed and direction of wind at the ocean surface, and TEMPEST provides atmospheric water vapor measurements.

2023年2月20日，国际空间站在印度洋毛里求斯岛国东北部267英里的上空，拍摄到了飓风弗雷迪的照片。

空间站上有两个NASA制造的气象仪器，即紧凑型海洋风矢量辐射计（COWVR）和风暴和热带系统时间实验（TEMPEST），它们追踪像弗雷迪这样的热带气旋。COWVR于2021晚些时候发射到空间站，测量海面风速和风向，TEMPEST提供大气水汽测量。
