Effect of solar activity on the frequency of occurrence of major anomalies in the Arctic

Major air pressure and temperature anomalies in certain arctic regions were studied with a view toward predicting their occurrence. Correlations are sought between the frequency of arctic anomalies and solar activity, or specifically the Wolf number and the index of geomagnetic disturbance. Graphic techniques are used to show that solar activity has a definite influence on the frequency of occurrence of major anomalies of pressure and temperature in the Arctic
