The correct statement regarding the QBO (Quasi-Biennial Oscillation) is:
2. The westerly phase of the QBO enhances Atlantic hurricane activity.
Explanation: The QBO describes the alternating easterly and westerly winds in the stratosphere over the equator, with a typical period of about 28 months. During the westerly phase, there is often a correlation with increased hurricane activity in the Atlantic due to effects on the atmospheric circulation patterns.
