at 10 m is usually low, while when the différence is large, also the latent heat flux
tends to increase. On the basis of the available information from this experiment,
it seems that at least a qualitative suggestion of a rôle of latent heat can corne from
the results. Future experiments, with the measurement of ail terms involved in the
enthalpy balance, are needed to confirm or reject the above suggestion.
