Meteorologfical Notes and Remarks upon the 

 Weather during- the Year 1906, with its General 

 Effects upon Vegetation. 



By James Whitton, Superintendent of Parks, Glasgow 



[Read 28th May, 1907.] 



In order to presei-ve the continuity of the series, these notes 

 have been compiled, as in former years, from the records kept 

 at Queen's Park, Glasgow. 



January. — The first day of the year was cold and dull, but 

 dry. In the early hours of the morning slight showers of snow 

 had fallen, but throughout the day was seasonable and enjoy- 

 able, despite the keenness of the easterly wind. These con- 

 ditions continued until the afternoon of the 3rd, when heavy 

 rain fell, and until the middle of the month the weather was 

 changeable and stormy, with a considerable rainfall. On the 

 8th a thick watery fog enveloped the city for several hours. 

 The latter half of the month was somewhat better than the 

 earlier, though high winds were of frequent occurrence. 



The changeable nature of the weather is well shown by the 

 irregular and erratic line of atmospheric pressure. On the 1st 

 the barometer indicated 29'70 inches, and on the 3rd, 29"20 

 inches; then, after varying several points up and down for several 

 days, there was a sharp decline to 28"80 inches on the 9th. 

 After quickly rising to 29"60 inches on the 11th, the pressure 

 kept within a few points of that figure for several days, then 

 from 29'25 inches on the 18th it rapidly rose to 30'00 inches 

 on the 19th, and to 30"30 inches on the 22nd. Then the pressure 

 declined to 29'40 inches on the 25th, after which date it again 

 increased, till on the 31st it indicated 30'00 inches. 



The rainfall was above the monthly average, 4' 74 inches 

 being registered, while there were only 8 dry days. In the 

 corresponding month of 1905 the rainfall was only 1'78 inches, 

 with 15 dry days.
