ABSTRACTS 



Authors of scientific papers are requested to see that abstracts, preferably 

 prepared and signed by themselves, are forwarded promptly to the editors. 

 Each of the scientific bureaus in Washington has a representative authorized to 

 forward such material to this journal and abstracts of official publications should 

 be transmitted through the representative of the bureau in which they originate. 

 The abstracts should conform in length and general style to those appearing in 

 this issue. 



METEOROLOGY. — Weather forecasting in the United States. Alfred 

 J. Henry and others. Weather Bureau Publication No. 583. 

 Pp. 370, with 199 charts and diagrams. 1916. (For sale by Super- 

 intendent of Documents, Washington, D. C.) 



It is a matter of common knowledge that although weather fore- 

 casts have been made in the United States for upwards of forty years, 

 scarcely anything has been written to explain in more or less detail the 

 processes by which weather forecasts are made. This volume is the 

 result of an attempt to put on record the rules and considerations 

 which have been found useful by experienced forecasters of the Weather 

 Bureau. The volume has been prepared primarily as an aid to begin- 

 ners in the art, and presupposes some acquaintance on the part of the 

 reader with graphic methods of presenting weather data. It is not for 

 general distribution. 



Preliminary chapters upon the theoretical aspects of the problem of 

 atmospheric motions have been contributed by C. F. Marvin and Wm. 

 J. Humphreys. 



The relation of atmospheric pressure distribution and of certain 

 well known barometric configurations to subsequent weather is dis- 

 cussed in three chapters by Alfred J. Henry. The well marked phe- 

 nomena of the weather, such as cold waves, frosts, high winds, fog, 

 snow, sleet, and thunderstorms, are discussed in four chapters; cold 

 waves and frosts are discussed by Henry J. Cox; high winds, by Edward 

 H. Bowie; fog, snow, and sleet, by H. C. Frankenfield. 



Three chapters, devoted to the routine forecasts of wind and weather, 

 are contributed by the district forecasters for the five forecast districts 

 of the country, and, finally, a chapter on long range forecasts is pre- 

 sented by E. H. Bowie. A bibliography concludes the work.
