WebDuring Rossby's lifetime there were no "Rossby waves", they started to appear with increasing frequency after his death in 1957. What he saw back in the late 1930's were called "planetary waves" and were baroclinic in nature. It was, however, possible, as Rossby showed in 1939-40, to describe their motion kinematically from a barotropic concept.
