Skyturbation
[skItu(r)'bey-shun]
1: perturbation of airmasses
2: event caused by using the scattered array antennas or lasers to heat a part of ionosphere by which that part of ionosphere could be heated up to 100 degrees Celsia above its previous temperature, and consequently the cold air masses are sucked underneath the heated air mass. In 21st century, used in the geoengineering experiments by various countries.
