Again, in the spring the frequency of the meridional flow types increases and the zonal flow type decreases. Apparently, cross-westerly heat trans- port and general lateral mixing are greatest in the spring and the autumn. In certain j^ears there is a distinct tendency for the extreme meridional flow types to continue with high frequencies on into the winter season. Since winter meridional flow types exhibit stronger abnormalities than those of autumn and spring, this leads to quite exceptional weather {viz., January, 1937 and 1949) and for this reason the phe- nomenon was studied in detail. The effect can best be.
