NASA and European partners launched the Sentinel-6B satellite in November to improve hurricane forecasting and related risk management. The satellite is now operating about 30 seconds behind its predecessor, Sentinel-6 Michael Freilich. Together, the pair provide precise measurements of sea-surface height, which oceanographers use to monitor ocean conditions that can influence hurricane activity.
Both outlets describe the current period as one expected to include a historic El Niño. El Niño is a naturally occurring warming of the central and eastern Pacific Ocean that can shift global weather patterns. Because hurricanes are affected by larger-scale ocean and atmospheric conditions, the improved sea-level data from the Sentinel-6 satellites are intended to support better understanding of how these conditions evolve.
The sources also note that the satellite program has broader uses beyond government forecasting. NASA highlights benefits for protecting infrastructure and for commercial sectors such as shipping, which can be affected by extreme weather and changing sea and storm conditions. Overall, the reporting emphasizes the satellites’ role in gathering detailed ocean measurements during an El Niño period.
