Short summary
According to classical theory, the ratio of turbulence statistics corresponding to transverse and longitudinal wind velocity components equals 4/3 in the inertial range of scales. We analyse a large number of measurements obtained with three research aircraft during four field experiments in different locations and show that the observed ratios are almost always significantly smaller. We discuss potential reasons for this disagreement, but the actual explanation remains to be determined.
