It corresponds closely with the Atlantic spur In the United States, and the correspondence pertains not only to the general continental location of the two stormy areas, but to their shape. Notice how the 68436--17--Sec 2 '27 dotted area In figure 1 extends northeastward along the Atlantic coast harmoniously with the northeastward elongation of the Japanese area in figure 4 along the Pacific coast. Flo. 3.--Storm In ess and storm tracks. Storminess In four grades: No storms, 1-10 centers per year, 11-20 centers, and over 20. Solid lines are centers of storm belts; dotted lines hypothetical ancient centers of belts. Taking the Northern Hemisphere as a whole, It seems as If the storms were primarily concentrated in a single great belt, which Is interrupted by continents and mountains, but is on the whole continuous. This, of course, is a fact universally recognized. I would add to It a suggestion of another sort. The two spurs of storminess In the United States and the two isolated areas In Italy and Japan suggest that possibly there is also a more southerly belt. At present It is not continuous. Its storms are usually drawn Into the main belt. Yet a certain number of American storms follow It In their whole course across the continent. In Europe also a certain number of Mediterranean storms seem to escape the attraction of the main storm belt, and continue across Syria to northern India. This at least Is the conclusion drawn by Walker (17) from a study of the relation of the winter rainfall of northern India to that of Persia, Mesopotamia, Syria, and the Mediterranean regions as.far west as Malta. Walker gives the following correlation coefficients between the rainfall of December to March In northwestern India and November to March In the places far...
