Excerpt from Annals of the Association of American Geographers, 1914, Vol. 4
Cyclonic and Anticyclonic Control of Our Own Weather and Cli mates - Most of the United States is well within the belt of prevailing westerly winds, one of whose most marked characteristics is the con tinuous procession of cyclonic and anticyclonic disturbances which keeps marching eastward in a great spiral circuit around the North Pole. Over the Temperate Zones, as a whole, there is thus a great ring of stormy weather, oscillating poleward and equatorward as the sun moves to and fro in the course of its regular migration. Northward, across the United States, to our northern border, swings this great storm belt as the summer sun comes north of the equator. Southward it swings in winter, following the declining sun, covering the country even to the Gulf of Mexico. Scattered through the southern quad rants of our cyclonic storms, especially during the warmer months, come more local disturbances - thunderstorms and tornadoes. There is, thus, a second belt of local storms, south of the general cvclonic storm belt. This, also, swings back and forth seasonally, covering practically the whole country in summer, and being carried well into and even across the southern States in winter.
