Gravity Waves Influence Weather and Climate

Gravity waves form in the atmosphere as a result of destabilizing processes, for example at weather fronts, during storms or when air masses stroke over mountain ranges. They can occasionally be seen in the sky as bands of cloud. For weather forecast and climate models, however, they are mostly 'invisible' due to their short wavelength.

Venus’s turbulent atmosphere

1. The atmospheric superrotation at the upper clouds of Venus. While the superrotation is present in both day and night sides of Venus, it seems more uniform in the day (AKATSUKI-UVI image at 360 nm, right side), while in the night this seems to become more irregular and unpredictable (composite of Venus Express/VIRTIS images ar 3.8 μm, left).

Examples of new types of cloud morphology discovered on the night side of Venus thanks to Venus Express (ESA) and the infrared telescope IRTF (NASA): stationary waves (Venus Express, up-left corner), "net" patterns (IRTF, up-right), mysterious filaments (Venus Express, down-left) and dynamical instabilities (Venus Express, down-right).
