12 Subtraction of the mean flow
recovers more flat (5/3?) spectrum

16 Strong condensate changes
sign of the third moment in the turbulence interval of scales Subtracting the mean flow restores the sign

20 Suppression of turbulence by a big vortex

21 Summary Condensates appear because of the inverse cascades
Condensates can suppress turbulence that feeds them Condensates can enhance and suppress fluctuations in different systems Negative third velocity moment does not negate an inverse cascade
