Global Precipitation & Temperature Outlook for November 2017

Global Precipitation & Temperature Outlook for November 2017

South Africa stands out in the November Outlook with a forecast of exceptionally hotter than normal temperatures. Much of Asia, Indonesia, and the southern and eastern US are expected to be warmer than normal. Much drier than normal conditions are expected in a path following the Andes from Colombia through Brazil, while wetter than normal conditions are forecast for the US Northern Plains states and pockets of central Africa.

Central Asia & Russia: Water surpluses forecast for Ob, Vakh, Tom Rivers, Russia

Central Asia & Russia: Water surpluses forecast for Ob, Vakh, Tom Rivers, Russia

Water surpluses reaching exceptional intensity are forecast in western European Russia, the Upper Ob River and Tom River Basins, and the Transvolga Region, where conditions of both deficit and surplus may emerge. Surpluses are also forecast for many parts of Kazakhstan, and in Kyrgyzstan. Severe to extreme deficits are forecast for the Yamal Peninsula and across the Gulf of Ob. Intense deficits in Turkmenistan and Uzbekistan are expected to diminish considerably leaving only mild deficits through December.

South Asia: Intense deficits forecast for Madhya Pradesh & N Telangana

South Asia: Intense deficits forecast for Madhya Pradesh & N Telangana

Intense water deficits are forecast through June 2018 in India’s central state of Madhya Pradesh. In the near-term, through December, severe to exceptional deficits are forecast for central states, and moderate deficits will extend north. Gujarat will transition to conditions of both deficit and surplus. Exceptional surpluses are forecast for Tripura, Mizoram, and Manipur, but surpluses are expected to recede in other northeastern states and in West Bengal. Surpluses of varying severity are forecast for Nepal and western Bhutan. Primarily moderate deficits are forecast for Pakistan and western Afghanistan.

Southeast Asia & the Pacific: Intense deficits to persist in W Cambodia

Southeast Asia & the Pacific: Intense deficits to persist in W Cambodia

The forecast indicates a gradual transition from predominantly surplus conditions to deficit. Western Cambodia and eastern Papua New Guinea, however, show deficit conditions throughout the 12-month forecast. Surpluses will begin to downgrade in the near-term but exceptional surpluses remain in the forecast through December for western Myanmar, northern and southern Laos, and along the west side of the Mekong River in Cambodia down to Phnom Penh. After December severe deficits will begin to emerge in Malaysia and Indonesia. 

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.
