Super Typhoon Sinlaku Generates Gravity Waves Observed in Atmosphere
US · Published Jun 1, 2026
Super Typhoon Sinlaku, a category 5 storm on the Saffir-Simpson scale, impacted the North Pacific Ocean and the Mariana Islands in mid-April
The storm not only caused heavy rain and flooding but also generated atmospheric gravity waves visible in the mesosphere. These waves were captured by the VIIRS (Visible Infrared Imaging Radiometer Suite) on the NOAA-20 satellite on April 12, 2026 (UTC). The AIRS (Atmospheric Infrared Sounder) instrument on NASA’s Aqua satellite also detected thermal energy from these waves in the stratosphere on April 13,
Gravity waves, which resemble ripples, are formed by intense convection near the storm's eyewall and propagate upward through the atmosphere. This phenomenon is significant for understanding storm intensification and its broader atmospheric impacts.

Why It's Important?

The gravity waves generated by Super Typhoon Sinlaku have implications beyond meteorological curiosity. These waves can influence stratospheric wind patterns, which are critical for long-term weather forecasting. Additionally, they can cause traveling ionospheric disturbances, potentially disrupting satellite signals and radio communications. The storm itself brought severe weather to the Mariana Islands, including heavy rainfall and flooding. The ability to monitor gravity waves could improve the prediction of storm intensification, especially over remote ocean areas where direct observations are limited.
