For over twenty years, the Joint Program in Physical Oceanography of MIT
and the Woods Hole Oceanographic Institution has based its education
program on a series of core courses in Geophysical Fluid Dynamics and
Physical Oceanography. One of the central courses in the Core is one on
wave theory, tailored to meet the needs of both physical oceanography
and meteorology students. I have had the pleasure of teaching of years,
and I have particularly enjoyed the response of the the course for a
number students to their exposure to the fascination of wave phenomena
and theory. This book is a reworking of course notes that I have
prepared for the students, and I was encouraged by their enthusiastic
response to the notes to reach a larger audience with this material. The
emphasis, both in the course and in this text, is twofold: the de-
velopment of the basic ideas of wave theory and the description of
specific types of waves of special interest to oceanographers and
meteorologists. Throughout the course, each wave type is introduced both
for its own intrinsic interest and importance and as a ve- hicle for
illustrating some general concept in the theory of waves. Topics covered
range from small-scale surface gravity waves to large-scale planetary
vorticity waves.
