I want to change the pixels to blue and make them look as smooth as any other turbulent region in the area.

LEt's say you want to change the values beyond a given value val (a number) into NaN. Use:
u(u>val) = NaN ;
isnan is afunction used to check whether a value is nan or not. You can check after replacing values with NaN using:
u(isnan(u))
