54 Gen. A. W.Greely — Rainfall Types of the United States. 



eastern Nebraska receives during these four months, April to 

 July, inclusive, a larger amount of rainfall than the interior 

 portions of the eastern states from Maine to Virginia; and western 

 Nebraska receives only a slightly lesser amount. While the 

 rain precipitation of the year diminishes to the northward and 

 westward of Nebraska, yet the same favorable type of distribu- 

 tion prevails. 



The Missouri type changes by interference with the Mexican 

 type in the southwest, the Tennessee type to the southeast, and 

 the Saint Lawrence to the northeast. 



The " Tennessee " type, although not covering a very extended 

 region, is well marked, the highest rainfalls occurring the last of 

 winter or the first of spring, while the minimum is in mid- 

 autumn. 



The Tennessee type obtains over Tennessee, Arkansas, Mis- 

 sissippi, eastern Kentucky, western Georgia and, except on the 

 immediate gulf coast, in Alabama and Louisiana. In some 

 localities (western Kentucky and Tennessee and adjacent parts 

 of Arkansas) the rain of February slightly exceeds that of March, 

 the usual month of maximum, while in northern Louisiana and 

 adjacent regions, the tendency is toward slightly greater rainfalls 

 in April than in March. 



It is also to be noted that in some cases there is a tendency 

 toward the minimum rainfall in August or September rather 

 than October, in which month the minimum occurs for the 

 greater portion of the area. 



Montgomery, Alabama ; Atlanta, Georgia; Chattanooga and 

 Memphis, Tennessee, are examples of the Tennessee type of pre- 

 cipitation.
