Just like waves form in the ocean or a lake when water is disturbed, waves also form in the atmosphere when air is disturbed. They form when air is forced upward by hills or mountains into a layer of stable air in the atmosphere. Gravity causes the air to fall back down, and it begins to oscillate, creating a ripple effect. Wind flowing over the Rocky Mountains, for example, can create gravity waves that are felt as turbulence on an airplane. || ", "release_date": "2023-10-25T15:00:00-04:00", "update_date": "2023-10-26T09:29:10.027006-04:00", "main_image": { "id": 860420, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a014400/a014445/14445_AGW_LakeSuperior_print.jpg", "filename": "14445_AGW_LakeSuperior_print.jpg", "media_type": "Image", "alt_text": "From the vantage point of the International Space Station, astronauts frequently observe atmospheric and surface phenomena in ways that are impossible to view from the ground. Two such phenomena—gravity waves and sunglint—are illustrated in this photograph of northeastern Lake Superior.Gravity waves are produced when moisture-laden air encounters imbalances in air density, such as might be expected when cool air flows over warmer air. This can cause the flowing air to oscillate up and down as it moves, causing clouds to condense as the air rises and cools and to evaporate away as the air sinks and warms. This produces parallel bands of clouds oriented perpendicular to the wind direction. The orientation of the cloud bands in this image, parallel to the coastlines, suggests that air flowing off of the land surfaces to the north is interacting with moist, stable air over the lake surface, creating gravity waves.Caption by William L.
