News Quote: By MIKE U. CRISMUNDO June 6, 2010, 3:05pm BUTUAN CITY – The Mines and Geosciences Bureau (MGB) of the Department of Environment and Natural Resources (DENR) and the Office of Civil Defense (OCD) in the Caraga Region on Sunday warned the public on the possible occurrences of landslides due to flashfloods as the La Niña phenomenon starts. In separate statements, the DENR-MGB and OCD directed all local government units (LGUs) to mobilize their respective disaster councils and review their respective mitigating measures to avert loss of lives and damage to infrastructure and agricultural lands.

PAGASA Daily inquirer Alcuin Papa က လာနီညာဆိုတာကို အခုလို မွတ္ခ်က္ေပးထားတာေတြ႕ရပါတယ္။
La Niña is the abnormal cooling of sea surface temperatures that cause heavy rainfall. – သူေျပာတာကေတာ့ လာနီညာဆိုတာဟာ ပင္လယ္ေရမ်က္ႏွာျပင္အပူခ်ိန္ အလြန္အမင္း က်ဆင္းသြားၿပီး အဲသလိုက်ဆင္းသြားတာေၾကာင့္ မိုးအရမ္းမ်ားလာတယ္” လို႕ ဘာသာျပန္ရမွာပါ။

NOAA ထုတ္ျပခ်က္မူရင္း
During La Niña episodes rainfall is enhanced across the western equatorial Pacific, Indonesia and the Philippines and is nearly absent across the eastern equatorial Pacific. Elsewhere, wetter than normal conditions tend to be observed during December-February (DJF) over northern South America and southern Africa, and during June-August (JJA) over southeastern Australia. Drier than normal conditions are generally observed along coastal Ecuador, northwestern Peru and equatorial eastern Africa during DJF, and over southern Brazil and central Argentina during JJA.

La Niña episodes also contribute to large-scale temperature departures throughout the world, with most of the affected regions experiencing abnormally cool conditions. Some of the most prominent temperature departures include: 1) below-normal temperatures during December-February over southeastern Africa, Japan, southern Alaska and western/central Canada, and southeastern Brazil; 2) cooler than normal conditions during June-August across India and southeastern Asia, along the west coast of South America, across the Gulf of Guinea region, and across northern South America and portions of central America; and 3) warmer than normal conditions during December-February along the Gulf coast of the United States.
