An analysis of the climatic changes from the 1921-50 period to the following 1951-60 and 1961-70 decades showed moderate synchronism in the annual and December-May changes of the circulation of the two regions as revealed by the intensity and position of the No. Pacific (Aleutian) and No. Atlantic (Icelandic) Lows. A filling-in and southwestward retreat of the Aleutian Low in the 1950's and 1960's in relation to the 1921-50 period was paralleled by a filling-in of the Icelandic Low in the same periods. This was accompanied by a lowering of the annual temperatures in the 1950's and a further lowering in the 1960's in Alaska and Iceland and also a lowering of the December-May temperatures in both regions in the 1950's and a further lowering in the 1960's in Iceland though not in Alaska, possibly due to a change in the site of the stations in the 1960's.
