Eight phase locations of MJO depict the different sections of the tropics through which the MJO propagates. Phase regions 1 to 3 represent west to central tropical Indian Ocean. Phase regions 4 and 5 depict the eastern Indian Ocean and Maritime Continent. Phases 6 to 8 represent west to central tropical … Meer weergeven To examine the mean state of the tropical ocean associated with the MJO frequency modes, we obtained the correlated seasonal mean SST anomalies of EOF1 and EOF2 time series (Fig. 1e,f). We observed that … Meer weergeven The relation between MJO frequency and ENSO phases are explored from a different perspective using the biplot technique. … Meer weergeven MJO frequency anomalies during two types of ENSO phases also can be visualized in the WH04 RMM1-RMM2 plane since … Meer weergeven Web13 apr. 2024 · Abstract The Madden–Julian oscillation (MJO) is the dominant intraseasonal wave phenomenon influencing extreme weather and climate worldwide. Realistic simulations and accurate predictions of MJO genesis are the cornerstones for successfully monitoring, forecasting, and managing meteorological disasters 3–4 weeks in advance. …

WebThe 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. Phase Averages Cloudiness Regional cloudiness Time longitude Tropical update About WebThe Madden–Julian oscillation moves eastward at between 4 m/s (14 km/h, 9 mph) and 8 m/s (29 km/h, 18 mph) across the tropics, crossing the Earth's tropics in 30 to 60 days—with the active phase of the MJO tracked by the degree of outgoing long wave radiation, which is measured by infrared-sensing geostationary weather satellites. scrollbar behavior

Web7 mrt. 2015 · The combined effect on precipitation over southern South America is dominated by the only-MJO phase component, with anomalies near to zero, except in phase 3. During La Niña winter periods, there are wet and cold anomalies (Fig. 6e, f, g, h) over the Amazon in all MJO phases and over southern Brazil in phases 1 and 3. scroll bar color change
