The rainfall and sunshine of Guernsey for the year 1904, A. Collenette 



(Guernsey Soc. Nat. Sci. Rpt. and Trans. 1904, pp. 391-399). — Observations on rain- 

 fall at 9 stations are summarized and compared with the averages for 62 years. The 

 total for the year was 37.72 in. as compared w ith an average of 36.62 in. for the past 

 62 years. A monthly summary of observations on sunshine during 1904 compared 

 with similar data for the preceding 11 years is also given. The total sunshine for 

 1904 was 1,925.75 hours as compared with an average of 1,927.11 hours for the past 

 11 years. 



Rainfall in the agricultural districts, (i. (i. Bond (Queensland Agr. .lour., n; 

 (1905), No. 1, p. 152). — A table is given which shows the total rainfall for each 

 month from June, 1904, to June, 1905, inclusive in 41 agricultural districts of 

 Queensland. 



Hourly observations of atmospheric phenomena at the Manila central 

 observatory, 1903 (Ann. Rpt. Philippine Weather Bur., 1903, pt. /, j>. 158, ph. 2).— 

 Detailed observations are recorded on pressure, temperature, precipitation, evapora- 

 tion, humidity, direction and force of wind. There are also general notes on the 

 weather conditions of the year. 



The heaviest rainfalls in the world {Jour. Mil. Russe, 1905, No. 1; abs. in 

 Nature [Paris]', 33 (1905), No. 1677, Sup., p. 25; Rev. Sci. [Paris'], 5. ser., 4 (1905), 

 No. 13, p. 408). — Tt is stated that the heaviest recorded rainfall in the world occurs 

 in Cherra Poonjee in the Indian Province of Assam. The mean annual rainfall of 

 this region from 1895 to 1903 was LI. 223 meters; that of the region of Bombay was 

 6.83 meters. The rainfall of Debundscha in Kamerun was 10.454 meters, principally 

 during the summer. The highest recorded rainfall during any given year at Cherra 

 Poonjee was 14.789 meters in 1851, at Debundscha 14. loo meters in 1902. At the 

 latter place 456 mm. of water fell during a single day, June 16, 1902. These heavy 

 rainfalls are explained as due to the proximity of warm seas and high mountains. 



Weather conditions and statistics {Ami. Rpt. Dept. Agr. Northwest Ter., 1904, 

 pp. 7-22). — This is a summary of observations during the year by the voluntary 

 meteorological service of the Northwest Territories on temperature and precipitation, 

 with notes on the general weather conditions during each month and the relation of 

 crop yields and temperature and precipitation. 



Forecasting the weather and storms, YV. I,. Moore (Nat. Geogr. Mag., 16 

 (1905), Xo. 6, pp. 255-305, />!*. 5, charts 20). — It is stated that this article is to consti- 

 tute the first chapter of a treatise to be entitled The New Meteorology. After a brief 

 historical note the preparation and use of the daily weather map is explained and 

 illustrated. 



A new method of determining the direction and velocity of storm movement de- 

 vised by E. H. Bowie, which is claimed to be "a marked advance over anything 

 heretofore accomplished in this direction," is fully described. The method is based 

 upon a study of the pressure gradients about the base of the storm, in connection 

 with the general drift of the upper air, thus making it possible "to obtain a result- 

 ant that approaches with close precision to the line of least resistance at the moment 

 of the taking of the observations on which the weather chart is founded. In the 

 majority of cases his system locates the place to which the storm center will move 

 during the coming 1*4 hours with considerable accuracy." 



Some aspects of modern weather forecasting, W. N. Shaw (Abs. in Nature 

 [London], 72 (1905), No. 1867, pp. 354, 355) .—In this address, delivered before the 

 Royal Institution of Great Britain, the close relation existing between weather con- 

 ditions and barometric distribution and changes is pointed out and some of the diffi- 

 culties in the way of quantitative association of rainfall or temperature changes with 

 barometric variations are discussed.
