The All-season Real-time Multivariate (RMM) MJO Index (Wheeler-Hendon) from the The Centre for Australian Weather and Climate Research. Bimodal ISO Index for historical data analysis and real time monitoring from the International Pacific Research Center.

2005年12月19日 · We construct ten MJO indices by regressing the daily data onto the ten patterns of the first EEOF. The figures below show the ten MJO indices (normalized) for the previous 6 and 12 months.

2005年12月12日 · A subgroup was organized to focus on MJO operational prediction and was tasked to develop a MJO forecast metric for comparison of dynamical models from operational global prediction systems. The decision was made for NCEP / CPC to host the application, display, and evaluation of these MJO model forecasts.

2025年3月24日 · The Madden-Julian Oscillation (MJO) is the major fluctuation in tropical weather on weekly to monthly timescales. The MJO can be characterised as an eastward moving 'pulse' of cloud and rainfall near the equator that typically recurs every 30 to 60 days.

2005年12月19日 · Phase diagram showing the evolution of the last 40 days of observations (black) along with the ensemble forecast. The yellow lines are the ensemble members and the red, blue, and purple lines are the ensemble mean denoting various time ranges of the forecast (red: days 1-7, blue: days 8-14, purple: >=day15).

馬登-朱利安振盪（Madden Julian Oscillation, MJO），也称热带季节内振荡或30-60日振盪。在北半球冬季，熱帶赤道地區有著顯著對流與無對流區塊交替出現的變化，主要以約30-60天的週期重複出現並向東前進，是大氣振盪的一種，屬於热带季內震盪(intraseasonal oscillation ...

The purpose of this page is to provide ways to assess and view the current MJO status. ROMI is computed using OLR only and as such is a purely convective index of the MJO. The EOFs depend on the day of year, latitude and longitude.

BoM MJO RMM: Real-time Multivariate MJO Index (with components of interannual variability removed). Wheeler, M. C. and H. H. Hendon, 2004: An all-season real-time multivariate MJO …

2022年9月9日 · "The Madden–Julian oscillation (MJO) is the largest element of the intraseasonal (30–90 days) variability in the tropical atmosphere. It is a large-scale coupling between atmospheric circulation and tropical deep convection.
