The forecast through May indicates the emergence of a vast stretch of extreme to exceptional water deficits in southern and eastern Mongolia and Inner Mongolia, China. Widespread surpluses will downgrade but persist in the Yangtze Basin’s Lower Reaches and in the southern portion of the Middle Reaches. Moderate deficits will emerge in Hainan and conditions in Taiwan will transition to near-normal. Intense deficits will emerge on the Korean Peninsula and will increase in much of Japan.
The January Outlook indicates much wetter than normal conditions forecast for southern China through the Pearl River Basin encompassing the Pearl’s northern tributaries; and, oceans away in Uruguay. Temperatures in Northeast China are expected to be exceptionally warmer than usual, anomalies with a return period of 40 or more years.
Widespread water surpluses will emerge south of the Yangtze River and in the Pearl River watershed over the next few months and may persist through March. Surpluses are also forecast for Sichuan, Qinghai, and Tibet and may persist even longer. Deficits will increase and intensify from western Inner Mongolia through Xinjiang, and moderate to severe deficits will emerge from the North China Plain to the Yangtze River. Extreme surpluses are forecast for southern Japan, and deficits for southern North Korea.
The near-term forecast through November indicates intense surpluses in China’s Jilin and Heilongjiang Provinces; along the Yellow River; in Shaanxi, southern Gansu, and Qinghai; and in Tibet. Surpluses are also forecast for southern China and Hokkaido, Japan. Deficits reaching exceptional intensity are forecast from western Inner Mongolia across much of Xinjiang. Deficits are also expected in the Lower and Middle Yangtze River Basin, South Korea, and southwestern Japan.
Through the next several months, widespread water surpluses in the center of China will shrink and downgrade, and surpluses further east in Hubei, Henan, and Anhui will transition to mild deficit. In the south, moderate to severe surpluses will increase in Yunnan and western Guangxi. Deficits will shrink in Mongolia, Inner Mongolia, and Southeast China. Moderate to extreme deficits will persist in Liaoning and Jilin in the northeast, and will emerge on the Korean Peninsula and Honshu, Japan.
Through September, exceptional water deficits in Mongolia, Inner Mongolia, and southern Xinjiang will diminish considerably, as well as in Southeast China and Taiwan. Moderate to severe deficits will persist in the Southeast with some pockets of exceptional deficit lingering in Hunan. Widespread surpluses will diminish overall, but surpluses of varying severity will persist in the Lower and Middle Reaches of the Yellow River, the Han River Basin, Qinghai, Yunnan, Hainan, and western Tibet.
Regions forecast to have significant water deficits for the 12-month period from March 2018 through February 2019 include: southern Mexico, northern Brazil, North Africa, Europe, Afghanistan, and Southeast China. Areas with a forecast of significant water surplus include: Montana and Idaho (US), Tanzania, Kenya, Uganda, Spain, and Bangladesh. This Watch List is based on ISciences Water Security Indicator Model (WSIM) run on 7 June 2018.
The forecast through June indicates that exceptional deficits in Mongolia, Inner Mongolia, and Xinjiang will diminish considerably. Deficits will increase in Northeast China; downgrade to mild in Shandong; and continue to emerge in the Southeast. Surpluses in the Yangtze Basin will diminish considerably, though exceptional surplus conditions are forecast for the Han River Basin. Hainan will transition from surplus to moderate deficit, as will Guangxi. Moderate deficit is forecast for North Korea. After June, water anomalies in China and Mongolia will downgrade overall.
Recent exceptional deficits in Mongolia, the Korean Peninsula, and Liaoning are expected to moderate in the near term – September through November. Widespread surpluses are expected to persist in southern China from Poyang Lake in Jiangxi southwest through Hunan into Guangxi and Yunnan, and the western Pearl River Delta, though the extent of exceptional surpluses will diminish considerably. The coastal southeast will transition from surplus to moderate deficit, a trend which is forecast to continue through May. After November, surpluses in Jiangxi through Yunnan will continue to diminish.
