oscillation
o suh lay shuhn
- n the process of oscillating between states
- n (physics) a regular periodic variation in value about a mean
- n a single complete execution of a periodically repeated phenomenon
- There are, however, indications that the El Nino cycle may be embedded in a longer-term oscillation, widely known as the PDO, or Pacific decadal oscillation.
- It's possibly part of a long-term but natural oscillation, like the decades-long cycles that already affect hurricanes.
- But the oscillation also appears to tweak the Northern Hemisphere's weather as well.
