Conclusion

Intermittency visualization

Experimental work in turbulence pointed out the existence of violent rare events, commonly referred to as worms.

Intermittency in turbulent field, (a) : Temperature increment, (b) : energy dissipation flux

(c) : distance traveled by the calanoid copepod Temora longicornis every 0.08 second, (d) : Time evolution of the studied rainfall time series
