  Mr. 
  R. 
  M. 
  Deeley 
  on 
  

  

  separating 
  the 
  two 
  wind 
  provinces 
  was 
  moving 
  westwards 
  at 
  

   about 
  29 
  miles 
  per 
  hour, 
  whereas 
  the 
  wind 
  following 
  it 
  up 
  

   was 
  only 
  moving 
  at 
  20 
  miles 
  per 
  hour. 
  Rain 
  was 
  falling 
  

   near 
  to 
  and 
  on 
  both 
  sides 
  the 
  dividing 
  line 
  between 
  the 
  winds. 
  

   The 
  upper 
  portion 
  of 
  the 
  westerly 
  wind 
  appears 
  to 
  have 
  

   been 
  travelling 
  more 
  rapidly 
  than 
  the 
  portion 
  near 
  the 
  ground, 
  

   and 
  was 
  descending 
  and 
  forcing 
  itself 
  beneath 
  the 
  more 
  

   southerly 
  wind. 
  The 
  latter 
  being 
  forced 
  to 
  rise 
  precipitated 
  

   some 
  of 
  its 
  moisture 
  through 
  the 
  lower 
  south-westerly 
  wind 
  

   as 
  well 
  as 
  along 
  its 
  westerly 
  margin.

  All 
  the 
  weather 
  charts 
  figured 
  are 
  for 
  the 
  area 
  of 
  the 
  

   British 
  Isles 
  and 
  portions 
  of 
  western 
  Europe. 
  The 
  points 
  

   where 
  rain 
  was 
  falling 
  were 
  generally 
  on 
  land, 
  observation? 
  

   out 
  at 
  sea 
  not 
  being 
  available 
  in 
  many 
  instances. 
  

  

  Occasionally 
  cyclones, 
  accompanied 
  by 
  rain, 
  do 
  occur 
  

   which 
  show, 
  even 
  as 
  far 
  as 
  their 
  lower 
  levels 
  are 
  concerned, 
  a 
  

   striking 
  resemblance 
  to 
  the 
  old 
  theoretical 
  cyclone*. 
  Fig.

   is 
  such 
  a 
  one. 
  Its 
  centre 
  lay 
  over 
  the 
  sea 
  between 
  Wales
