インド洋海水温、3年連続異常＝アフリカなど大雨懸念－海洋機構


7月15日4時33分配信 時事通信
　海洋研究開発機構は15日までに、インド洋の東部で海面水温が平年より下がる異常現象「ダイポールモード」（IOD）が3年連続で発生した可能性が高いと発表した。1950年代の観測開始以来初めてで、インドやアフリカ東部では大雨、インドネシア西部では少雨が懸念される。　IODは、2006年には太平洋東部の海面水温が平年より高くなるエルニーニョ現象、07年には逆に低くなるラニーニャ現象と同時発生。日本では、06年は西日本、07年は全国的に猛暑となった。

{Paper} 081116! Recent intensification of tropical climate variability in the Indian Ocean

Recent intensification of tropical climate variability in the Indian Ocean Nature Geoscience Published online: 16 November 2008 doi:10.1038/ngeo357 Nerilie J. Abram 1 , 2 , Michael K. Gagan 1 , Julia E. Cole 3 , Wahyoe S. Hantoro 4 & Manfred Mudelsee 5 The interplay of the El Niño Southern Oscillation, Asian monsoon and Indian Ocean Dipole (IOD) 1, 2, 3 drives climatic extremes in and around the Indian Ocean. Historical 4, 5 and proxy 6, 7, 8, 9 records reveal changes in the behaviour of the El Niño Southern Oscillation and the Asian monsoon over recent decades 10, 11, 12 . However, reliable instrumental records of the IOD cover only the past 50 years 1, 3 , and there is no consensus on long-term variability of the IOD or its possible response to greenhouse gas forcing 13 . Here we use a suite of coral oxygen-isotope records to reconstruct a basin-wide index of IOD behaviour since AD 1846. Our record reveals an increase in the frequency and strength of IOD events during the tw...

{News} 080804 Haze returns to region as Sumatra's illegal fires rage

Haze returns to region as Sumatra's illegal fires rage The Straits Times, Aug 4, 2008 Despite fire-fighting efforts, visibility just 2km in Riau; air over Malaysia worsens By Teo Cheng Wee, In Kuala Lumpur and Salim Osman, Indonesia Correspondent In Jakarta HAZE shrouded parts of the region yesterday after fires scorched forest and plantation land in Sumatra over the weekend, enveloping the Riau capital of Pekanbaru and parts of Peninsular Malaysia. The authorities have squarely blamed Indonesian farmers and plantation workers, who are clearing the land using slash-and-burn methods that have been banned since 1999. The number of hot spots in Sumatra surged from 351 to 531 on Saturday, before dipping to 360 yesterday, according to the Indonesian Meteorology and Geophysics Agency (BMG). This was confirmed by Singapore's National Environment Agency. BMG analyst Selamat Triyadi told The Straits Times that Riau alone accounted for some 136 hot spots, while Pelalawan and Rokan Hulu h...
