The three-dimensional (3-D) structure of stratospheric Kelvin waves is revealed using data from the Microwave Limb Sounder for the period July 1992 to April 1993. Four Kelvin wave modes are identified, two for zonal wave number 1 (k = 1) and two for k = 2, using extended empirical orthogonal functions. The 3-D structures of the modes agree with linear theory and satisfy the dispersion relation for Kelvin waves, and with periods ranging from 4.5 to 10 days the modes mostly fall near the boundary between ‘‘fast’’ and ‘‘slow’’ Kelvin waves [Canziani et al., 1998]. The analysis also identifies a feature that may correspond with the ‘‘pancake structures’’ associated with inertial instability.
