Chinese Weather Experts Expect El Nino to Form Soon

Jun 19, 2014     Email"> PrintText Size

Chinese meteorological experts are forecasting that an El Nino weather pattern could start to affect the country as early as next month, and may hurt domestic rice and corn production. 

Ding said an El Nino could reduce global grain output, but the damage could be more devastating if the weather pattern persisted.

El Nino, a warming of sea-surface temperatures in the Pacific, can disrupt weather across the entire ocean region. It has previously triggered flooding in China's southern rice-growing regions and caused droughts in corn-producing areas of the north. 

"According to our forecasts, we are basically sure that El Nino will happen, and the key issue right now is how strong it will be," said Ding Yihui, a climate change adviser to the China Meteorological Administration, according to a transcript of a meeting posted on the administration's website (www.cma.gov.cn). 

Zheng Fei, a researcher at the Institute of Atmospheric Physics under the Chinese Academy of Sciences, estimated at the same meeting that the probability of an El Nino striking was more than 70 per cent for July and 80 per cent for August. 

The forecasts from China are in line with those in Australia, the United States and Japan. 

"Historic data showed that El Nino could have a big impact on corn crops in the north," said Zheng Dawei, a professor at the China Agricultural University. He said droughts triggered by El Nino in 2009 reduced corn output in the north. 

Dry weather has already begun in parts of northern China and could worsen in autumn, he said. 

The country's rice harvest could also be affected, said Zheng. An El Nino triggered the worst flooding along China's Yangtze River in half a century in 1998, killing thousands as swollen rivers burst their banks and destroying crops. 

Ding said an El Nino could reduce global grain output by between 2 and 2.4 per cent, but the damage could be more devastating if the weather pattern persisted for two or three years. 

He said droughts triggered by El Nino events in 1972 had inflicted severe water shortages on several Chinese cities. 

Ding forecast the El Nino's strength could peak around the end of 2014, when temperatures were likely to rise above average. Some experts were estimating temperatures around 2-4 degrees Celsius higher than normal, he added. (Reuters)
