The Madden–Julian oscillation is the largest element of the intraseasonal variability in the tropical atmosphere. It was discovered in 1971 by Roland Madden and Paul Julian of the American National Center for Atmospheric Research. What is Mjo in geography? 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. What is the main source of intra seasonal climate variability in the tropics? The Madden-Julian oscillation (MJO), sometimes known as the intraseasonal oscillation (ISO), is the leading mode of intraseasonal variability in the tropical climate system. What causes the Madden-Julian Oscillation? The wet phase of enhanced convection and precipitation is followed by a dry phase where thunderstorm activity is suppressed. Each cycle lasts approximately 30–60 days. Because of this pattern, the
Focused on advancing knowledge and expertise in Geography, GIS, Remote Sensing, Geographical Data Science, and Analysis, I am deeply committed to teaching and conducting research in these fields. With a keen interest in leveraging data-driven approaches for informed decision-making, I specialize in crafting maps that facilitate effective analysis and interpretation of spatial information.
