Madden-Julian Oscillation (MJO)
Definition
MJO is an eastward moving disturbance of clouds, rainfall, winds, and pressure that traverses the planet in the tropics and returns to its initial starting point in 30 to 60 days, on average.
MJO Analysis
MJO can be characterised using wavelength-frequency analysis of vaiables such as the outgoing longwave radiation.
