The phenomena are very complex as many physical, time and chemical scales are involved, therefore turbulent combustion instabilities multiscale 4D problems (space and time), like vortex breakdown and vortex precessing core [3, 4], appear.
Downward moving wind and temperature anomalies associated with rapid vortex breakdown appear to influence the Jet Streams and project strongly onto the AO.
