食品伙伴網(wǎng)訊  據(jù)美國媒體消息，12月16日美國航空航天局（NASA）發(fā)布研究報告指出，解決加州持續(xù)3年的大旱尚需42萬億升水，是美國最大水庫蓄水量的1.5倍。

    上次“菠蘿快車”風暴帶來的降水可謂是“杯水車薪”。本次研究數(shù)據(jù)首次使用NASA的重力監(jiān)測及氣象試驗（Gravity Recovery and Climate Experiment）衛(wèi)星，估算解決干旱所需的地下水量得出。

    部分原文報道如下：

    If you figured the storms that wreaked havoc on California this month would signal the end to the state's historic drought, think again.

    Storms this month dropped 11 inches of rain in some parts of the state and triggered mudslides in other areas, damaging many homes. The deluge helped bump up the state's largest reservoir from 26 percent to 31 percent of capacity and dumped 94 billion gallons - about a one-year supply for 540,000 families.
