SYDNEY - An El Nino weather pattern this year appears almost certain,
Australia's Bureau of Meteorology said on Wednesday in a revised forecast,
raising the prospect of drought in Australia and a even weaker monsoon in
India.
The odds for El Nino, an abnormal warming of the eastern Pacific Ocean that
creates havoc in weather patterns across the Asia-Pacific region, had risen
significantly since two weeks ago, when the bureau said there was a more
than 50 percent chance.
"El Nino is a little bit like recession, you are in it before you can say
you have one. If it continues as it is now, the historians will say the El
Nino started in May," said David Jones, head of the bureau's climate
analysis, told Reuters.
He said they could declare a full El Nino within weeks.
That's probably bad news for farmers in Australia who have sown near record
acreage, and in India, which is already bracing for below-average monsoon
rains, the lifeblood of the country's agriculture.
It would also have implications for commodity markets, potentially lifting
wheat prices that have slumped over the past month on expectations of a
bumper global harvest, and adding further fuel to soaring sugar prices that
are already bracing for a second disappointing crop year from top consumer
India.
Most of Australia's 2009/10 wheat crop has been planted following plentiful
rain, leading to forecasts of a harvest of as much as 23 million tonnes, the
best since 2005/06 when 25.2 million tonnes were harvested.
"The growers I speak to say if we were to get some rains in spring we could
get above average yields. But if the El Nino forecast materialized, we are
again at risk of having a sub-standard crop," said Richard Koch, managing
director of farm advisory firm Profarmer.
Australia's grain production is still recovering from the worst drought in
more than 100 years that cut the annual wheat harvest to as little as 10.6
million tonnes in 2006/07.
India's weather office last week cut its forecast for the June-September
monsoon rains by 3 percentage points to 93 percent of normal, after four
years of above average rainfall. From June 1 to June 24 rains were 54
percent below normal.
A severe El Nino spawns searing drought in countries in southeast Asia,
harming rubber production, while causing heavy flooding in Peru, Ecuador and
Chile, among others.
LITTLE CHANCE OF AVOIDING EL NINO
The bureau's latest report found that the eastern Pacific Ocean was
continuing to warm, with sea temperatures one degree Celsius above normal,
and trade winds were continuing to weaken.
The Southern Oscillation Index (SOI), calculated from monthly and seasonal
fluctuations in air pressure between Tahiti and Darwin, remained at around
negative 2, while the monthly value for May was negative 5.
A sustained negative SOI often indicates El Nino.
"A more complete picture of the situation in the Pacific will be available
next week when the final June indices are calculated," said the report on
www.bom.gov.au/climate/enso/
The next report is due on July 8.
The Climate Prediction Center in the United States said in June that
conditions were favorable for a switch to El Nino conditions during June to
August.
