Findings from University of California Has Provided New Data on Hydrology (A baseline probabilistic drought forecasting framework using standardized soil moisture index: application to the 2012 United States drought)

By a News Reporter-Staff News Editor at Science Letter -- Investigators discuss new findings in Hydrology. According to news reporting originating from Irvine, California, by NewsRx editors, the research stated, "The 2012 drought was one of the most extensive drought events in half a century, resulting in over USD 12 billion in economic loss in the United States and substantial indirect impacts on global food security and commodity prices. An important feature of the 2012 drought was rapid development and intensification in late spring/early summer, a critical time for crop development and investment planning."

Our news editors obtained a quote from the research from the University of California, "Drought prediction remains a major challenge because dynamical precipitation forecasts are highly uncertain, and their prediction skill is low. Using a probabilistic framework for drought forecasting based on the persistence property of accumulated soil moisture, this paper shows that the US drought of summer 2012 was predictable several months in advance. The presented drought forecasting framework provides the probability occurrence of drought based on climatology and near-past observations of soil moisture."

According to the news editors, the research concluded: "The results indicate that soil moisture exhibits higher persistence than precipitation, and hence improves drought predictability."
