Weekly Weather Notes (abbreviated from the Weekly Weather Report 

 of the Meteorological Office). 



Weather, unsettled. Barometer and Wind: Throughout the week the 

 barometer was relatively high in Icelmd and Spain while cyclonic 

 disturbances either extended or travelled across U. K. These systems 

 were not as a ride deep, and the wind which was mainly between S and W 

 had little force. In the rear of a moderate depression which passed 

 across the North of England on Thursday, the barometer rose briskly 

 and the wind "veered to IN W or N over the whole of U. K. and increased in 

 force. 



Weather, dry, cloudless. Barometer and Wind : Distribution mainly 

 anticyclonic. At first the pressure maximum was over France, and it 

 travelled from there to Germany, and to Scandina\ia. During the latter 

 part of the week a large cyclonic system appeared over the Bay of 

 Biscay. This was accompanied by an E wind over England and a SE 

 wind over Scotland At the end of the week a well-marked but not 

 deep depression travelled southward over Scandinavia and highest 

 pressure existed in Iceland. 



Weather, fine. Barometer and Wind: At the beginning of the week the 

 barometer was highest in Iceland and lowest to S.W. of U. K., and in 

 Germany. A moderate NE breeze was blowing. On Monday the anti- 

 cyclone extended over these islands. Later it moved NW to the 

 Atlantic and a depression born in the Shetlands travelled to Finland by 

 Thursday. After this small disturbances travelled southward over U. K. 

 and the North Sea. The general direction of the wind was between 

 N and NW sometimes W and sometimes E. 



Weather, fine and dry. Barometer and Wind : The distribution of pressure 

 underwent several changes though the barometrical movements were not 

 brisk. Pressure which was highest over Iceland gradually gave way 

 while it was sometimes highest to the S., E., and N.E. of U.K. JNo 

 important depressions passed over U. K.., but towards the end of the week 

 a large system was spreading in slowly from the Atlantic. Wind, light 

 and variable except in latter half ot week when it was S & SW.
