2019年5月21日 · The MJO can be defined as an eastward moving 'pulse' of clouds, rainfall, winds and pressure near the equator that typically recurs every 30 to 60 days. It’s a traversing phenomenon and is most prominent over the Indian and Pacific Oceans.

2024年8月2日 · The Madden Julian Oscillation (MJO) is a prominent tropical climate pattern that involves the periodic movement of cloud and rainfall activity across the equator. It is significant for its role in modulating weather patterns globally, including influencing the strength and distribution of monsoons and cyclones.

2024年11月27日 · The Madden Julian Oscillation (MJO) is a large-scale mutualistic coupling between atmospheric circulation and tropical deep convection characterised to occur as an eastward-traveling disturbance of cloud amount, rainfall, winds and pressure near the equatorial region that extends over an entire 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.

The Madden–Julian oscillation is characterized by an eastward progression of large regions of both enhanced and suppressed tropical rainfall, observed mainly over the Indian and Pacific Ocean. The anomalous rainfall is usually first evident over the western Indian Ocean, and remains evident as it propagates over the very warm ocean waters of ...

2023年12月12日 · Madden-Julian Oscillation (MJO) is a weather phenomenon that affects both the ocean and the atmosphere. It involves disturbances in wind, clouds, and air pressure, which travel eastward at a speed of 4-8 meters per second. This movement of the MJO has a significant impact on weather patterns worldwide.

The MJO can be defined as a disturbance of clouds, wind and pressure, moving eastward at a speed of 4-8 metres per second, MJO goes around the globe in 30-60 days on average. Sometimes, it can take 90 days. It’s a traversing phenomenon and is most prominent over the Indian and Pacific Oceans.

2019年11月28日 · Strong MJO activity often dissects the planet into halves: one half within the enhanced convective phase and the other half in the suppressed convective phase. These two phases produce opposite changes in clouds and rainfall and this entire dipole that is having two main opposing centres of action propagates eastward.

Madden Julian Oscillation is a transverse phenomenon and is said to go through eight phases. MJO brings a good amount of rainfall over the Indian subcontinent when it is over the Indian ocean during the Monsoon season. In contrast to this, when MJO remains on the Pacific Ocean with a longer cycle, there is a lack of rainfall in the Indian Monsoon.

2020年11月13日 · In this article, You will read El-Nino, La-Nina, ENSO, El Nino Modoki, Madden-Julian Oscillation (MJO) – for UPSC (Geography). El-Nino and La Niña are opposite phases of what is known as the El Niño-Southern Oscillation (ENSO) cycle.
