East Asia: Water surpluses forecast to diminish in Yangtze Basin, increase in Pearl

East Asia: Water surpluses forecast to diminish in Yangtze Basin, increase in Pearl

Water surpluses in the Yangtze Basin are forecast to diminish in extent from September through November, while to the south surpluses in the Pearl River basin will increase. Water deficits are expected to increase from the Shandong Peninsula westward to the Tibetan Plateau, and deficits are also forecast for Shanghai. Elsewhere in the region deficits are forecast in Taiwan and South Korea during this period; surpluses are forecast for Hokkaido, Japan. From December through February surpluses along the Yellow, Yangtze, and Pearl Rivers will moderate.

East Asia: Water surpluses to persist on Yellow River & lower Yangtze River

East Asia: Water surpluses to persist on Yellow River & lower Yangtze River

Moderate to exceptional water surpluses are forecast to persist in China along the Yellow River and the lower reaches of the Yangtze River through October. Deficits will continue to emerge in Shandong, eastern Yunnan, and western Guangxi. Widespread deficits are forecast for the Korean Peninsula from September on, and deficits will continue to emerge in Southeast and Northeast China. Deficits may recede in Honshu, Japan in October before re-emerging.

East Asia: Water surpluses to persist on middle & lower reaches of Yangtze

East Asia: Water surpluses to persist on middle & lower reaches of Yangtze

Water surpluses are expected to persist in many provinces of China along the middle and lower reaches of the Yangtze River through September though surpluses will not be as severe or widespread as in previous months. In November southeast China will begin to transition from surplus to moderate deficit which will gradually encompass much of the country. Deficits will emerge on the Korean Peninsula in October. By November deficits in Japan will spread in Honshu, Shikoku, and Kyushu.

East Asia: Water surpluses to persist in Southeast China, deficits in Japan

East Asia: Water surpluses to persist in Southeast China, deficits in Japan

Water surpluses are expected to persist, though diminish in severity, in many provinces of China along the Yangtze River and south in the coming months, and then transition to moderate deficits beginning in November. Severe surpluses are forecast along the Yellow River in June. Deficits are forecast in Hainan June through August. Moderate to severe deficits are forecast in Hokkaido, central Honshu, and Shikoku, Japan from June through August, and deficits may continue to emerge in some areas of Japan through February.

East Asia: Water surpluses persist in SE China, will emerge in Henan & eastward

Widespread moderate to exceptional water surpluses are forecast to persist in southeast China and the Yangtze River. Surpluses are also forecast along the Yellow River beginning in May, which may become extreme in June. A transition to moderate deficits is forecast for southeast China in the later months. Moderate deficits are forecast in Mongolia, and both deficits and surpluses are forecast in western regions of China including the Tibetan Plateau. 

Many analyses reported in ISciences-authored blog posts are based on data generated by the ISciences Water Security Indicator Model (WSIM). Other sources, if used, are referenced in footnotes accompanying individual posts. WSIM is a validated capability that produces monthly reports on current and forecast global freshwater surpluses and deficits with lead times of 1-9 months at 0.25°x0.25° resolution. This capability has been in continuous operation since April 2011 and has proven to provide reliable forecasts of emerging water security concerns in that time-frame. WSIM has the ability to assess the impacts of water anomalies on people, agriculture, and electricity generation. Detailed data, customized visualizations, and reports are available for purchase.
