NASA Satellites Detect Gravity Waves Above Typhoon Sinlaku After Category 2-to-5 Surge
1 articles · Updated · Science@NASA · Jun 1
VIIRS and AIRS data showed gravity waves radiating from Super Typhoon Sinlaku into the stratosphere and mesosphere as the storm intensified over the North Pacific in mid-April.
In the 24 hours before the key observation, Sinlaku strengthened from a category 2 to a category 5-equivalent storm, with latent heat and towering convection near the eyewall driving the waves upward.
Nearly complete rings appeared in mesospheric airglow—an unusually clear signal that researchers said was helped by light stratospheric winds and only 25% moon illumination, which limited reflected cloud glare.
The observations could improve monitoring of rapid intensification over open ocean, where direct measurements are sparse, and support arguments for geostationary infrared sensors tuned to track such waves.
Researchers said the waves also matter beyond storm forecasting because tropical cyclones can force the stratosphere, affect seasonal weather patterns, and trigger ionospheric disturbances that disrupt satellite and radio signals.
As typhoons create waves in space, how will this new data help forecast future super storms fueled by our warming planet?
Beyond flooding coastlines, how do super typhoons now pose a direct threat to our global satellite and communication networks?
With a record El Niño brewing, is Super Typhoon Sinlaku a preview of an unprecedented season of extreme weather for 2026?
Gravity Waves Unleashed: Lessons from Super Typhoon Sinlaku (2026) for Cyclone Forecasting and Climate Models
Overview
Super Typhoon Sinlaku became the strongest storm of 2026, making a rare and devastating April landfall as a Category 5 cyclone across Saipan, Tinian, and Guam. Its arrival outside the usual typhoon season brought torrential rain and extreme winds, setting new records and signaling the onset of El Niño. The storm’s unusual timing and intensity highlighted the challenges of disaster response in remote islands. Sinlaku also generated powerful atmospheric gravity waves, which were detected by advanced satellites and are now recognized as important for understanding and forecasting tropical cyclone behavior and their broader impacts on weather and climate.
