ANSWER: The tilt of the earth
Explanation:
Researchers have discovered a connection between earth’s tilt called obliquity and shifts every 41,0000 years and the movement of a low pressure band of clouds that is the largest source of heat and moisture for the earth namely the ITCZ or Intertropical Convergence Zone. Study reveals that earth’s tilt plays a much larger role in ITCZ migration than previously determined. This will enable climate scientists to better predict extreme weather events.
