Q: What is the Madden-Julian Oscillation (MJO)?

Arab Weather - Madden-Julian Oscillation (MJO) is a pattern of atmospheric oscillation that occurs in tropical regions, and includes the movement of areas of storm activity and convection (upward air currents) from west to east across the Indian and Pacific Oceans. This oscillation occurs at intervals ranging from approximately 30 to 60 days.

MJO effects include:

1. Changing tropical weather patterns: such as thunderstorms and rainstorms.
2. Impact on tropical cyclones: May enhance cyclone formation in the Indian and Pacific Oceans.
3. Linked to climate phenomena: such as El Nino and La Nina.
4. Impact on global climate: through its influence on extratropical weather systems.
