the <\/span><b>tenth instance since 1960<\/b><span style=\"font-weight: 400;\"> that nationwide monsoon coverage occurred in June.<\/span><\/li>\n<\/ul>\n<h3><b>Low Pressure Systems<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">India experienced five low-pressure systems in June.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">These act as moisture magnets, drawing in rain-bearing winds and accelerating monsoon movement inland.<\/span><\/li>\n<\/ul>\n<h3><b>Active Madden-Julian Oscillation (MJO)<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">MJO is a moving system of clouds, rainfall, winds, and pressure near the equator that travels eastward.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">When active near India, it enhances monsoon by increasing cloud cover and moisture, leading to stronger rainfall.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">An active MJO phase significantly boosts monsoon onset and progression.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">June continued to see an active MJO, enhancing cloud formation and pushing rainfall northwards, aiding monsoon spread.<\/span><\/li>\n<\/ul>\n<h3><b>Favourable Monsoon Trough Position<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The monsoon trough is an elongated low-pressure area extending from northwest India to the Bay of Bengal.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">It plays a key role in determining rainfall distribution during the monsoon.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">A favourable monsoon trough position, especially when it shifts south of its normal, helps draw in moisture-laden winds from the oceans, intensifying rainfall over central and northern India.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Its position influences the strength, spread, and duration of monsoon rains.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The monsoon trough remained south of its normal position, facilitating increased moisture inflow and early rainfall across regions.<\/span><\/li>\n<\/ul>\n<h3><b>Neutral ENSO (El Ni\u00f1o-Southern Oscillation) Condition<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">ENSO is a climate pattern involving temperature fluctuations in the central and eastern tropical Pacific Ocean, with three phases: <\/span><b>El Ni\u00f1o, La Ni\u00f1a, and Neutral<\/b><span style=\"font-weight: 400;\">.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">A neutral ENSO phase means sea surface temperatures are close to average.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">This <\/span><span style=\"font-weight: 400;\">phase neither suppresses nor excessively enhances rainfall, allowing the Indian monsoon to progress normally, supporting stable and widespread rainfall patterns<\/span><span style=\"font-weight: 400;\">.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">ENSO was in a neutral phase, supporting normal monsoon rainfall.<\/span><\/li>\n<\/ul>\n<h3><b>Neutral IOD (Indian Ocean Dipole) Conditions<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">An is a climate phenomenon marked by differences in sea surface temperatures between the western and eastern Indian Ocean.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">It has positive, negative, and neutral phases.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">A <\/span><span style=\"font-weight: 400;\">neutral IOD phase means there is little to no temperature difference between the two regions, resulting in minimal influence on the Indian monsoon<\/span><span style=\"font-weight: 400;\">.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">This allows monsoon rainfall to be primarily driven by other favorable factors like MJO and ENSO.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">This year, IOD also remained neutral, having minimal impact\u2014neither enhancing nor suppressing rains.<\/span><\/li>\n<\/ul>\n<h2><b>Conclusion<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">This year\u2019s monsoon has been marked by early onset, rapid progression, sudden pauses, and localised weather disasters.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">With much of the season still ahead, it remains uncertain whether the pattern will
