The storm reached \u201cviolent typhoon\u201d status\u2014the highest intensity on\u00a0<a href=\"https:\/\/www.data.jma.go.jp\/multi\/cyclone\/cyclone_caplink.html?lang=en\" rel=\"noopener\">the scale<\/a>\u00a0used by the Japan Meteorological Agency and roughly equivalent to a category 5 storm on the\u00a0<a href=\"https:\/\/www.nhc.noaa.gov\/aboutsshws.php\" rel=\"noopener\">Saffir-Simpson wind scale<\/a>. Sinlaku was one of only a handful of <a href=\"https:\/\/oceanservice.noaa.gov\/facts\/cyclone.html\" rel=\"noopener\">tropical cyclones<\/a> of that intensity known to have occurred so early in the year in the region, <a href=\"https:\/\/yaleclimateconnections.org\/2026\/04\/cat-5-super-typhoon-sinlaku-the-2nd-strongest-typhoon-so-early-in-the-year\/\" rel=\"noopener\">meteorologists noted<\/a>.<\/p>\n<p>Sinlaku rapidly intensified over the ocean before its impacts reached land. Around the time of this strengthening,\u00a0satellites began to detect that the typhoon\u2019s effects also extended upward, into the <a href=\"https:\/\/science.nasa.gov\/earth\/earth-atmosphere\/earths-atmosphere-a-multi-layered-cake\/\" rel=\"noopener\">upper atmosphere<\/a>.<\/p>\n<p>The nighttime image above, acquired with the\u00a0<a href=\"https:\/\/www.earthdata.nasa.gov\/data\/instruments\/viirs\" rel=\"noopener\">VIIRS<\/a>\u00a0(Visible Infrared Imaging Radiometer Suite) on the\u00a0<a href=\"https:\/\/science.nasa.gov\/mission\/jpss\/\" rel=\"noopener\">NOAA-20<\/a>\u00a0satellite, shows atmospheric gravity waves radiating from the typhoon. These waves, resembling ripples on a pond, were made visible to the sensor via <a href=\"https:\/\/www.nasa.gov\/solar-system\/why-nasa-watches-airglow-the-colors-of-the-upper-atmospheric-wind\/\" rel=\"noopener\">airglow<\/a> in the mesosphere. Airglow occurs when atoms and molecules, <a href=\"https:\/\/www.snexplores.org\/article\/scientists-say-excitation-definition-pronunciation\" rel=\"noopener\">excited<\/a> by sunlight during the day, later emit light to release excess energy.<\/p>\n<p>The release of latent heat near the eyewalls of tropical cyclones is known to drive convection and the formation of tall cumulonimbus clouds. These \u201c<a href=\"https:\/\/svs.gsfc.nasa.gov\/3253\/\" rel=\"noopener\">hot towers<\/a>\u201d can rise out of the troposphere, the lowest layer of the atmosphere, and generate waves that propagate into the stratosphere and mesosphere above. An <a href=\"https:\/\/doi.org\/10.1002\/2017GL076123\" rel=\"noopener\">analysis of past tropical cyclones<\/a> revealed that gravity waves often occur around the time that storms are intensifying. Indeed, in the 24 hours prior to the acquisition of the image above, Sinlaku had <a href=\"https:\/\/www.wunderground.com\/hurricane\/western-pacific\/2026\/typhoon-sinlaku\" rel=\"noopener\">strengthened<\/a> from a category 2 to a category 5 storm.<\/p>\n<p>\u201cWe\u2019re seeing waves propagating radially and upward, in a cone-like shape,\u201d said <a href=\"https:\/\/www.cora.nwra.com\/~alexand\/\" rel=\"noopener\">Joan Alexander<\/a>, senior research scientist at NorthWest Research Associates. Alexander was surprised to see well-defined waves in the mesospheric airglow above the storm. Winds in the upper atmosphere can dissipate the waves before they reach such high altitudes, Alexander explained, but relatively light stratospheric winds at the storm\u2019s latitude in April 2026 may have helped preserve them.<\/p>\n<p>A relatively low amount of moonlight was fortuitous, as well. The VIIRS\u00a0<a href=\"https:\/\/www.earthdata.nasa.gov\/news\/blog\/announcing-viirs-nighttime-imagery-day-night-band\" rel=\"noopener\">day-night band<\/a>\u00a0is sensitive to airglow in the mesosphere but also observes reflected moonlight. The Moon was about <a href=\"https:\/\/catalina.lpl.arizona.edu\/moon-phases\/month\/2026-04\" rel=\"noopener\">25 percent illuminated<\/a> on April 12, so some light reflected off clouds in the troposphere was visible, but not enough to overpower the signal from the airglow.<\/p>\n<div id=\"\" class=\"hds-media hds-module wp-block-image\">\n<div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\">\n<div class=\"hds-media-wrapper margin-left-auto margin-right-auto\">\n<figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-none \"><a href=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/eo\/images\/iotd\/2026\/gravity-waves-from-super-typhoon-sinlaku\/sinlakugravitywaves_airs_20260413.jpg?w=2160&#038;h=2355&#038;%23038;fit=clip&#038;%23038;crop=faces%2Cfocalpoint\" rel=\"noopener\"><img decoding=\"async\" width=\"2160\" height=\"2355\" src=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/esd\/eo\/images\/iotd\/2026\/gravity-waves-from-super-typhoon-sinlaku\/sinlakugravitywaves_airs_20260413.jpg?w=2160&#038;h=2355&#038;%23038;fit=clip&#038;%23038;crop=faces%2Cfocalpoint\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"The signature of gravity waves in the stratosphere appears as concentric rings in infrared satellite data.\" style=\"transform: scale(1);

Practical implications could include improved monitoring of storm development. \u201cWe\u2019d like to use gravity waves to tell us if a storm is intensifying,\u201d Alexander said, \u201cwhich can be difficult to know, especially over the open ocean.\u201d A <a href=\"https:\/\/science.nasa.gov\/earth\/earth-observatory\/catalog-of-earth-satellite-orbits\/#hds-sidebar-nav-1\" rel=\"noopener\">geostationary<\/a> satellite with the proper infrared imager would be able to observe gravity waves and track <a href=\"https:\/\/agupubs.onlinelibrary.wiley.com\/doi\/10.1002\/2017GL076123#:~:text=proxy%20for%20the%20evolution%20of%20TC%20intensity\" rel=\"noopener\">tropical cyclone evolution<\/a>, she and colleagues have argued.<\/p>\n<p>Furthermore, it\u2019s critical to account for processes in the stratosphere in weather models, said Laura Holt, also a senior research scientist at NorthWest Research Associates. Stratospheric wind patterns are factors in long-term forecasts of the next Northern Hemisphere winter, for example, and tropical cyclones have a disproportionate influence because their sustained, intense convection drives prolonged gravity wave forcing of the stratosphere.<\/p>\n<p>The effect of gravity waves even reaches into the realm of space weather. \u201cFor a while, people have seen signatures of hurricanes in <a href=\"https:\/\/science.nasa.gov\/earth\/earth-observatory\/a-golden-look-at-the-ionosphere-146043\/\" rel=\"noopener\">ionospheric<\/a> weather,\u201d Holt said. Gravity waves can lead to traveling ionospheric disturbances\u2014large-scale ripples in plasma density\u2014and in some cases <a href=\"https:\/\/doi.org\/10.3390\/atmos13101637\" rel=\"noopener\">plasma bubbles<\/a>, both of which can disrupt satellite signals and radio communications. \u201cWith space weather in particular,\u201d Holt added, \u201ca single event such as a tropical cyclone can be very important.\u201d<\/p>\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<p><em>NASA Earth Observatory images by Michala Garrison,\u00a0using VIIRS day-night band data from NASA\u00a0<a href=\"https:\/\/www.earthdata.nasa.gov\/data\/projects\/lance\" rel=\"noopener\">EOSDIS LANCE<\/a>, <a href=\"https:\/\/worldview.earthdata.nasa.gov\/\" rel=\"noopener\">GIBS\/Worldview<\/a>, and the <a href=\"https:\/\/www.nesdis.noaa.gov\/our-satellites\/currently-flying\/joint-polar-satellite-system\" rel=\"noopener\">Joint Polar Satellite System<\/a> (JPSS), and AIRS data from <a href=\"https:\/\/doi.org\/10.26165\/JUELICH-DATA\/LQAAJA\" rel=\"noopener\">Hoffmann, L<\/a>.
