该基金支持的研究由北极系统科学(ARCSS)全球变化研究计划主持,并由海洋科学部和极地项目办公室联合赞助。即将进行的工作是一项名为“示巴”的重大5年研究项目的初步步骤,该项目旨在研究北冰洋的热量收支及其对全球变化的影响。SHEBA的主要目标是:(1)开发、测试和实施北极海洋-大气-冰过程的模式,这些模式明显改善了使用环流模式(GCMs)对当今北极气候(包括其变率)的模拟;(2)改善北极卫星遥感数据的解释,用于北极气候系统的分析,并为模式输入、模式验证和气候监测提供可靠的数据。加州大学圣地亚哥分校的研究人员将于1997年在拟议的冰营所在地建造一台仪器,用于测量海冰下的垂直和水平热量和动量通量。拟议中的声纳系统将提供混合过程的精确测量,这将提高模型预测北极海洋内产生的热收支组成部分的能力。??
英文摘要
Research supported by this grant is under the auspices of the Arctic Systems Science (ARCSS) Global Change Research Program and is jointly sponsored by the Division of Ocean Sciences and the Office of Polar Programs. Work to be performed represents preliminary steps towards a major 5-year research project named SHEBA, which is envisioned to study the heat budget of the Arctic Ocean and its impact on global change. The primary goals of SHEBA are: (1) to develop, test and implement models of arctic ocean-atmosphere-ice processes that demonstrably improve simulations of the present day arctic climate, including its variability, using General Circulation Models (GCMs), and (2) to improve the interpre- tation of satellite remote sensing data in the Arctic for analysis of the arctic climate system and provide reliable data for model input, model validation and climate monitoring. Researchers at the University of California, San Diego will build an instrument that will measure the vertical and horizontal flux of heat and momentum under the sea ice at the location of the proposed ice camp in 1997. The proposed sonar system will provide accurate measurements of mixing processes that will improve the ability of models to predict the component of the heat budget of the Arctic that is produced within the ocean. ??
