Abstract

It is suggested that Eulerian mean velocities and eddy fluxes are not necessarily identical with those observed by (quasi-Lagrangian) GHOST balloons. Although a general relationship between the two sets of variables has not been established, it is argued, on the basis of a number of simple examples, that differences can emerge that are related to the turbulence statistics of the flow. Such differences are known to exist in other fluid systems.
