摘要：
Airborne infrared imagery is shown to provide preliminary evidence of surface thermal expressions associated with internal waves that become unstable and break over the continental shelf. These expressions include a narrow wave front that is warmer than the ambient; a wide, spatially intermittent 'wake' that is colder than the ambient; and similar to O (10m) diameter surface-renewal 'boils' that populate the wake. These thermal signatures might be useful in assessing the spatial distribution and structure of breaking internal waves. Published by Elsevier Ltd.
