Abstract:
Connections, sometimes tenuous, have previously been noted between stratospheric
Kelvin waves and several stratospheric trace constituents. The present study finds
evidence of Kelvin wave signatures in ozone from the Microwave Limb Sounder (MLS)
and Cryogenic Limb Array Etalon Spectrometer (CLAES) instruments aboard the Upper
Atmosphere Research Satellite. Predominant variations near 10 days are associated with a
Kelvin wave mode previously identified in MLS temperature. Variations in CLAES
nitrous oxide also show some evidence of influence by this Kelvin mode. The results
presented here show that the observing characteristics of the instrument can influence the
derived structure and properties of Kelvin waves.
