May 21, 2019 · According to India Met Department (IMD), the Arabian Sea arm of south-west monsoon is counting on an itinerant Madden-Julian Oscillation (MJO) wave for normal monsoon. It is an oceanic-atmospheric phenomenon which affects weather activities across the globe.
The Madden–Julian oscillation moves eastward at between 4 m/s and 8 m/s 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.
Unlike a standing pattern like the El Niño–Southern Oscillation (ENSO), the Madden–Julian oscillation is a traveling pattern that propagates eastward, at approximately 4 to 8 m/s (14 to 29 km/h; 9 to 18 mph), through the atmosphere above the warm parts of the Indian and Pacific oceans.
Dec 31, 2014 · Here we introduce another important player on the tropical stage: the Madden-Julian Oscillation, or MJO. While the MJO is a lesser-known phenomenon, it can have dramatic impacts in the mid-latitudes.
The Madden-Julian Oscillation is a mode of sub-seasonal atmospheric variability that influences the location and strength of tropical precipitation as in this classic schematic (left) from Rol Madden and Paul Julian.
Overview. According to the RMM-based MJO index, the MJO was weak since the beginning of June. The 200-hPa velocity potential anomaly field became less coherent the past few weeks although there is a remnant MJO signal crossing the Western Hemisphere.
Madden-Julian Oscillation (MJO) 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.
Madden-Julian oscillation (MJO), intraseasonal fluctuation of atmospheric pressure over the equatorial Indian and western Pacific oceans, named for American atmospheric scientists Roland Madden and Paul Julian in 1971. This phenomenon comes in the form of alternating cyclonic and anticyclonic.
Jun 30, 2005 · The Madden-Julian Oscillation (MJO) is the dominant component of the intraseasonal (30–90 days) variability in the tropical atmosphere. It consists of large-scale coupled patterns in atmospheric ci...
The Madden-Julian Oscillation is characterised by an eastward spread of large regions of enhanced and suppressed tropical rainfall, mainly observed over the Indian and Pacific Ocean. It was...
