Preparation for Collaborative Work on Past Climate in Jordan

9527740 Hughes该奖项支持前往约旦建立一个利用树木年轮进行古气候研究的合作项目的可行性。由此产生的项目的目标是发展过去几个世纪以来近东这一地区的树木年轮气候记录，作为了解气候年际到世纪尺度变化的国际努力的一部分。该地区目前在这类记录中很少有代表性。填补全球覆盖的这一空白将带来好处，使我们能够更全面地描述中纬度地区的气候变率，从而提高了解这方面气候变率的能力。这项研究将提高我们在这些时间尺度上理解区域环境关键特征的环境变异性的能力，例如干旱的持久性、河流的可靠性。

9527740 Hughes This award supports travel to Jordan to establish the feasibility of developing a collaborative program of paleoclimatic research using tree rings. The objective of the resulting project would be to develop tree-ring records of climate over the past several centuries for this part of the Near East, as part of an international effort to understand interannual to century scale variability in climate. The region is currently poorly represented in records of this kind. Benefits derive from filling this gap in global coverage, enabling a more thorough description of climate variability in mid-latitudes and hence an improved capability to understand this aspect of climate variability. This study will improve our capability to understand environmental variability on these time scales of key features of the regional environment, e.g. persistence of drought, reliability of streamflow.
