The weather office revised its southwest monsoon forecast to 88 per cent of average rainfall with the El Nino effect apparently having taken hold, presenting the Narendra Modi government with a cha

Monsoon watchers are scanning the Indian Ocean for any sign that could potentially reduce the impact on seasonal rains from a raging El Nino away in the equatorial Pacific.

The monsoon is likely to arrive in Kerala on May 30 -as predicted by India Meteorological Department -but it may be weak because of El Nino's impact, IMD scientists have indicated.

Prospects are firming that the latest El Nino event may leave much of Australia drier, with conditions in the Indian Ocean possibly reinforcing those in the Pacific, the Bureau of Meteorology says.

Why this weird weather?

The world’s oceans are playing a game of hot potato with the excess heat trapped by greenhouse gas emissions.

The monsoon is likely to hit India two days ahead of its normal onset date, the India Meteorological Department announced on Thursday even as the possibility of below-par rainfall grew, with both I

The northeastern part of the Indian Ocean, i.e. the Bay of Bengal (BoB) is located near some of the most complicated tectonic zones on the Earth. An earthquake of magnitude ~6.0 occurred on 21 May 2014 near the coast of Odisha. Occasional moderate to large earthquakes in BoB highlight the need to study precise hypocentre locations, and focal mechanisms to understand the cause of intraplate seismicity in BoB.

When does an El Nino (warming of the east and equatorial Pacific) create widespread rain deficit over India during the monsoon?

This paper presents key results from analysis of surface meteorological observations collected in the Northern Arabian/Persian Gulf (N Gulf; Kuwait, Bahrain, and NE Saudi Arabia), which spans a 40-years period (1973–2012). The first part of this study analyzes climate variability in the N Gulf, and relates them to teleconnection patterns (North Atlantic Oscillation, El Nino Southern Oscillation, and Indian Ocean Dipole).
