               Marine Corps Air Station El Toro, California is    
          located in the southern section of an area known  as    
          the  "Los  Angeles  Basin".   The  air  station   is    
          screened  on 3 sides by mountain barriers.  Land  in    
          the immediate vicinity of the station is cleared and    
          cultivated and under extensive urbanization. 
		             
               The region in which the air station is  located    
          enjoys  one  of the most equable climates  in  North    
          America.   The  summer  begins in  April  and  lasts    
          through October.  Increased stability in the form of    
          haze,   fog  and  stratus.   The   prevailing   wind    
          direction is west at about 5 knots.  
		                     
               The   dry  easterly  winds  (Santa  Ana)   that    
          sometimes  blow  for several days at a  time,  bring    
          temperatures  in  the 90's, and at  times  over  100    
          degrees  F.  Since September 1949, this station  has    
          recorded  a  total of 25 days which were  under  the    
          influence of the "Santa Ana" winds. 
		                      
               The  "Santa  Ana" wind that is  experienced  at    
          this  station may occur in almost any month  of  the    
          year;   however,  it  is  predominately   a   winter    
          phenomenon.    
		                                           
               Precipitation  at this station is  primarily  a    
          winter   phenomenon.   The   average   rainfall   is    
          approximately 12 inches and the major portion of  it    
          usually  falls during winter storms.  Snow has  been    
          observed at this station upon rare occasions and the    
          accumulation has been negligible.
