Weekly Weather Notes (abbreviated from the Weekly Weather Report 

 of the Meteorological Office). 



Weather, much less bright. Barometer and Wind : Depressions from the 

 Atlantic of variable size and no great depth, travelled over these islands 

 and the pressure changes were consequently frequent and rather consider- 

 able. The wind was generally light find moderate between SW and W 

 except in Scotland where it was SSE and E. A strong breeze or high 

 wind prevailed for a time on our southern coast on Wednesday. 



Weather, fine and bright, then extremely unsettled. Barometer and Wind : 

 In the early part of the week a large V-shaped depression travelled 

 eastwards across U. K., and light to moderate breezes were experienced 

 from S & SW to NW & N. After Wednesday a well defined cyclone 

 spread northwards from Spain and NE breezes set in over all XJ. K. 

 an increase in the strength of the wind occurring on Thursday. Towards 

 the end of the week the southern depression gradually dispersed and the 

 wind backed to N and became light. 



Weather, cloudy, dry. Barometer and Wind : Soon after the week com- 

 menced a large anticylone extended gradually over these islands from the 

 Atlantic, and by Tuesday almost the whole kingdom was under its 

 influence. During the latter half of ihe week, however, it retreated 

 very slowly westwards while shallow ill-defined disturbances appeared 

 over theNorth Sea and to the S.E. of England. The general direction of 

 the wind was N and NW but it varied somewhat in places. 



WeatJier, dry, cloudy. Barometer and Wind : During the greater part of 

 the week the barometer was high over the Atlantic and low in Denmark 

 and the general current of air was from the North During the end of 

 the period the Atlantic system moved to the Bay of Biscay and France, 

 and depressions began to affect the north and north-west of U. K., so that 

 the wind backed .to NW and eventually to W and SW. 



Weather, dull. Barometer and Wind : The depression at the N.W. of U. K. 

 gradually extended over U. K. The winds were SE and strong.
