Table of Contents


I. Introduction

Learn about the purpose and the contents of this training module.


II. Lee Waves

General information about lee waves, their appearance in satellite imagery and appearance from the ground, time of the year they appear and atmospheric conditions affecting them.


III. A Special Case Of Lee Waves: The Foehn Clouds

As any other phenomenon, lee waves also have their special case: the foehn clouds. They appear during the periods of foehn wind, a wind characterized by high temperature advection due to adiabatic heating.


IV. Physical Background Of Lee Waves

Physical explanation of lee waves. Two types of lee waves depending on their propagation. Appearance of lee waves in satellite imagery with examples.


V. Gravity Waves In Satellite Images

About gravity waves and their characteristics. Why do the evolve and how do we see them in satellite imagery?


VI. Physical Background Of Gravity Waves

Physical explanation of (internal) gravity waves. The important feature is the relation between gravity and bouyancy force.


VII. Shear-Gravity Waves In Satellite Images

In contrast to gravity waves, shear-gravity waves need a highly unstable atmosphere. Learn more about them here.


VIII. Kármán Vortex Streets

What are they? How do they form and how do they look in the satellite imagery?
