The World Meteorological Organization’s State of the Climate in Asia 2024 report warns that the region is warming nearly twice as fast as the global average, driving more extreme weather and posing serious threats to lives, ecosystems, and economies. In 2024, Asia experienced its warmest or second warmest year on …
The symposium report focuses on mitigation strategies for tsunami disasters, tsunami warning systems and historical and pre-historical tsunamis associated with earthquakes in the Indian Ocean. This symposium report focuses on mitigation strategies for tsunami disasters, tsunami warning systems and historical and pre-historical tsunamis associated with earthquakes in the Indian Ocean. …
The report, Resilience Assessment of Coral Reefs - Rapid assessment protocol for coral reefs, focusing on coral bleaching and thermal stress, shows that the amount of damage done to corals depends not only on the rate and extent of climate change, but also on the ability of coral reefs to …
Warming of the seas is rerouting monsoon THE monsoon winds are avoiding India for one-third of the months of July and August and taking a route south of its peninsula. This is because the winds have found a highly attractive low pressure region in the eastern part of the Indian …
Thiruvananthapuram: Satellite data from the US National Atmospheric and Space Administration (NASA) and a new modelling approach could improve weather forecasting and save more lives when future cyclones develop. About 15 percent of the world's tropical cyclones occur in the northern Indian Ocean, but because of high population densities along …
On December 26, 2004 Sri Lanka and a few other countries in the region faced the destructive power of nature. The tsunami that swept across the Indian Ocean left about 300,000 people dead. This disaster also demonstrated the regenerative power of human compassion. Sri Lanka became just one household where …
Fundamental to the onset of the Indian Summer Monsoon is the land-sea thermal gradient from the Indian Ocean to the Himalayas-Tibetan Plateau (HTP). The timing of the onset is strongly controlled by the meridional tropospheric temperature gradient due to the rapid pre-monsoon heating of the HTP compared to the relatively …
This case study is part of the ODI HPG research programme on the role of the affected state in humanitarian action and aims to describe the essential elements of approach to disaster management as seen in its response to the 2001 Gujarat earthquake and the 2004 Indian Ocean tsunami. It …
The tsunami of the recent past has put into perspective the need for assessing tsunami hazard in vulnerable coastal areas of India. Following the disastrous tsunami in the Indian Ocean on December 26th 2004, the Ministry of Earth Sciences initiated action towards setting up of the Tsunami Warming System at …
SYDNEY - Droughts in Australia have traditionally been linked to El Nino events in the Pacific Ocean, but a new study says the key driver of major droughts has been a warming and cooling cycle in the Indian Ocean. The research shows Australia's major droughts over the past 120 years, …
This report provides an overview of priorities for tsunami early warning systems in the Indian Ocean and Southeast Asia. It aims to guide the policy and programming of the ESCAP Multi-Donor Voluntary Trust Fund on Tsunami Early Warning Arrangements in the Indian Ocean and Southeast Asia. It also intends to …
600 years ago, a tsunami hit the Indian Ocean. Some lessons THE Indian Ocean Tsunami System Programme, costing US $16. 6m, ended in March this year, amidst hopes that it would check the devastation that occurred in 2004. The 2004 tsunami
The coastal waters off western India may be the largest natural low-oxygen system. In summer and autumn the oxygen level drops to 0.2 mg per litre, said S W A Naqvi, chemical oceanographer at National Institute of Oceanography in Goa. During these seasons, the institute
Increasing amount of soot, sulphates and other aerosol components in atmospheric brown clouds (ABCs) are causing major threats to the water and food security of Asia and have resulted in surface dimming, atmospheric solar heating and soot deposition in the Hindu Kush-Himalayan-Tibetan (HKHT) glaciers and snow packs. These have given …
The processes that control climate in the tropics are poorly understood. We applied compound-specific hydrogen isotopes (D) and the TEX86 (tetraether index of 86 carbon atoms) temperature proxy to sediment cores from Lake Tanganyika to independently reconstruct precipitation and temperature variations during the past 60,000 years. Tanganyika temperatures follow Northern …
A new study, co-funded by NASA, has identified a link between a warming Indian Ocean and less rainfall in eastern and southern Africa. Computer models and observations show a decline in rainfall, with implications for the region
In this study, using 104 years (1901–2004) of high resolution daily gridded rainfall data, variability and long-term trends of extreme rainfall events over central India have been examined. Frequency of extreme rainfall events shows significant inter-annual and inter-decadal variations in addition to a statistically significant long term trend of 6% …
