have been thoroughly studied (see Fig. 21), and measurements of the 

 intensity of temperature turbulence have been executed. 



These results are given in a number of publications: Resch 

 [ 1968, 1970] , Resch and Coantic [ 1969] , Ezraty and Coantic [ 1970] , 

 Ezraty [ 1970] . They show conclusively that, subject to some pre- 

 cautions, turbulence nneasurements can be quite accurately per- 

 formed in water flows, using hot-film anemothemometers. 



2. Measurements of Turbulent Fluctuations of Humidity 



After the theoretical study reported in II. 4, the development 

 of a water vapor turbulence measuring technique has been undertaken. 

 Various methods have been considered: psychrometry, dew-point 

 measurement, use of hot-wire, absorption of Lyman alpha or infrared
