El Niño years have twice the average precipitation, and La Niña years have one quarter of the average precipitation. If all years are either El Niño or La Niña (i.e. no neutral years), how often does El Niño occur?
What if you allow neutral years?
Answer to Quizlet 1: Northbound, port-side
Seeing something setting means you are looking West. If it is rotating counter-clockwise, then you are rotating clockwise. Facing West + rotating clockwise means Northbound. If you are Northbound and looking West, you must be on the left (port) side of the aircraft.

Though to look smart I am reading a book on string theory!
BTW - uh, why the new look?
OK, so I may have missed the itty bitty banner at the top saying "Your comment has been saved and will be visible after blog owner approval" a few times. Please forgive the 500,000,000 comment submission attempts!
So, here is my off the cuff guess... El Niño would happen about every other year... with neutral years it would still happen at any time after one year of La Niña... perhaps if we looked at a greater year span we might see two years of La Niña for every El Niño...
