Temperatures acquired by the Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere (CRISTA) during shuttle mission STS-66 have provided the first unambiguous measurements of stratospheric mountain waves from space. Large-amplitude long-wavelength mountain waves at heights 15-30 km above the southern Andes were observed and characterized, with vigorous wave breaking inferred above 30 km. Mountain waves also occurred throughout the stratosphere (15-45 km) over a broad mountainous region of central Eurasia. These global distributions of mountain wave activity accord well with predictions from a mountain wave model. The findings demonstrate that satellites can now provide the global data needed to improve mountain wave parameterizations, and hence global climate and forecast models.
