Weekly Weather Notes (abbreviated from the Weekly Weather Keport 

 of the Meteorological Office). 



Weather, wintry. Barometer and Wind : The general distribution of pressure 

 favoured winds from some point between N & E. In addition to a large cyclone 

 of irregular form that extended over this country early in the week a well defined 

 system moved southward over Britain and the North Sea during Tu and W, and 

 finally disappeared in the Netherlands. On Friday a band of relatively low 

 pressure extended from the Atlantic over the N part of these islands and winds 

 became W. But on Saturday the advance of a deep cyclone to our S.W. coasts 

 drew wind into NE & SE. 



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

 depression had arrived and lay over England causing complete cyclone circu- 

 lation. This system moved SE across the Channel. The barometer meanwhile 

 stood highest in Iceland and N. Europe, but later in the week the pressure gave 

 way over Norway and became high out West. Wind changed from NE to 

 N and increased in force. 



Weather, unsettled. Temperature, low at first but rose later. Barometer fy Wind : 

 At the commencement of the week a depression covered the North Sea and the 

 general winds were N. This continued till Tuesday when a shallow low- 

 pressure system appeared between Scotland and Ireland, and wind backed to W 

 & SW. This was followed by another cyclone irom the Atlantic, deep at first 

 but which got shallow as it travelled over U.K. The wind after blowing 

 strongly SE on our S.W. coasts veered to S and became light. 



Weather, unsettled. Barometer and Wind: During nearly the whole of the week 

 depressions either extended slowly or passed directly over U. K. while the 

 barometer was high in Iceland and Spain. The centre of the chief system passed 

 over Yorkshire Wednesday night. As it increased considerably in depth 

 during its passage the wind blew a strong breeze or high wind between SW 

 & S on the south coast and E & NE in the north, while in the rear on Friday 

 a NW breeze was general. On Saturday another cyclone was approaching. 



Weather, unsettled; finer after Wednesday. Barometer and Wind : During the 

 greater part of the week depressions passed across U. K. while the barometer 

 was high in Iceland and Spain. After a rapid passage of one on Wednesday 

 an anticyclone set in from the north, and the barometer rose rapidly. This 

 increased in size and intensity as it passed across the North Sea on Saturday. 

 With the cyclonic distribution the wind was W & SW in the south and 

 strongly E in the north.
