  Shaw 
  and 
  Lempf 
  ert 
  to 
  have 
  been 
  due 
  to 
  the 
  mounting 
  of 
  the 
  

   southerly 
  current 
  over 
  the 
  northerly 
  and 
  westerly 
  wind 
  on 
  its 
  

   westerly 
  margin. 
  

  

  But 
  there 
  are 
  other 
  phenomena, 
  of 
  which 
  rain 
  and 
  wind 
  

   are 
  features, 
  which 
  are 
  not 
  the 
  result 
  of 
  great 
  differences 
  of 
  

   barometric 
  pressure, 
  but 
  arise 
  from 
  the 
  variable 
  heating

  and 
  cooling 
  of 
  the 
  land 
  and 
  water 
  areas 
  by 
  the 
  sun. 
  In 
  

   the 
  Troposphere 
  we 
  have 
  the 
  atmosphere 
  in 
  a 
  condition 
  

   approaching 
  convective 
  equilibrium 
  ; 
  due 
  to 
  the 
  upward 
  rise 
  

   of 
  heated 
  air, 
  such 
  air 
  cooling 
  by 
  expansion 
  as 
  it 
  rises. 
  

   There 
  is 
  a 
  generally 
  held 
  opinion 
  that 
  the 
  full 
  moon 
  dissipates 
  

   the 
  clouds. 
  The 
  fact 
  that 
  clouds 
  often 
  melt 
  away 
  after 
  sunset 
  

   is 
  probably 
  the 
  cause 
  of 
  this 
  view. 
  During 
  the 
  day 
  in 
  quiet 
  

   weather, 
  the 
  air 
  over 
  the 
  land 
  is 
  more 
  heated 
  than 
  is 
  the 
  case 
  

   over 
  the 
  surrounding 
  seas, 
  and 
  it 
  rises, 
  thereby 
  producing
