SAR IMAGING OF INTERNAL GRAVITY WAVES: FROM ATMOSPHERE TO OCEAN

This paper is dedicated to the "40 Years of Ocean Remote Sensing - a Session to Honor W. Alpers on the Occasion of his 80th Birthday". In this paper, a list of Alpers' research contributions in understating the atmospheric gravity waves and oceanic internal waves are highlighted along with up-to-date research finding in these fields. On the atmospheric side, we presented the SAR observation of atmospheric gravity waves (AGW) generated at the lee side of a mountain ridge and the upstream propagating waves. WRF simulation is carried out to understand the generation, propagation and decay of the AGW. On the oceanic side, internal wave (IW) observations in the South China Sea are presented. We present model simulation to understand the mechanisms that cause the IW reflection.
