Abstract
Simultaneous observations of space correlations and time correlations verify that Taylor's hypothesis x = Ut is valid for intervals up to at least 90 m, and for relative intensities of turbulence at least up to 0·26. It is also shown that, when the stratification is stable, the longitudinal scale of turbulence tends to be much larger along the flow than across it. In an unstable layer, the scale is of the same order of magnitude in all directions.Keywords
