Figure 3.— POLYMODE experiments. 



Theoretical Program 



The U.S. Core Program also contains substantial theo- 

 retical and numerical modelling elements, and U.S. theoreti- 

 cians and modellers are actively engaged in the exchange of 

 ideas and techniques with colleagues from the U.S.S.R. and 

 other nations. The theoretical program is necessarilly broader 

 that the field experimental program, and involves fundamental 

 investigations, numerical model developments, intercomparison 

 and verification, and dynamical analysis of field data. 



Table 6 lists U.S. participants in POLYMODE.
