| What is the MJO and why do we care? | A short tutorial on the MJO from the Climate.gov ENSO blog. |
| MJO monitoring page | From NOAA/CPC. Includes various plots of the current status of the 30-60 day oscillation including OLR anomalies, geopotential height and other animations and satellite photos. Also includes a FAQ on the oscillation mechanism and evolution and its relationship to other climate processes. They also have a MJO daily index. |
| Wikipedia page on the MJO | Description, behavior, and connection to weather events. |
| World Climate Service: The Madden Julian Oscillation | Introduction, behavior and measurement. |
| All-season Real-time Multivariate MJO Index | Forecast and monitoring plots of the MJO that utilize and empirically derived structure of the MJO based on historic data and include predictions for Australia from the Australian Bureau of Meteorology. |
| Multi-Scale MJO Research Page | From Woods Hole Oceanographic Institution. The tropical Dynamics lab researches the MJO and how it interacts with waves and the mean state of the atmosphere/ocean. |
| PSL Spotlight Article on the MJO (August 2001) | The MJO and its effect on the onset of an El Niño event. |

Plot Phase Diagrams using MJO Indices
|
Choose from an MJO index to get a phase plot for an input range of dates. |
| Interactive MJO Composites | Choose MJO to get list of high/low MJO activity days. Use these days on the page daily composite page to obtain composites for different variables. |
| Time Section Plots | Plots time/latitude and time/longitude plots of NCEP reanalysis and operational data. Plots means and anomalies. |
| Plot Daily Data | Plots maps or crossections of daily and daily averaged data. Includes anomalies, means and climatologies. Includes OLR. |
