A Dendroclimatic Study of Drought in the Northern Great Plains

树木年轮年表提供了过去气候最重要的记录之一。这些记录提供了陆地气候变化的年度分辨率和明确的记录。本研究项目将重建地球历史上近三百年来北美大平原北部干旱的规模和频率。该研究的地理位置在以往的古气候研究中被忽视。由于该地区是美国重要的农业区，了解该地区的干旱历史对于了解未来气候变化及其对粮食供应的可能影响非常重要。

Tree-ring chronologies provide one of the most important records of past climate. These records provide annual resolution and unambiguous records of terrestrial climatological change. This research project will reconstruct the magnitude and frequency of drought in the northern Great Plains of North America for last three-hundred year interval of earth history. The geographic location for this study has been neglected in previous paloeclimate research. Since it is an important agricultural region for the US, understanding the history of drought in this region is important for understanding future climate changes and their possible effect on food supplies.
