Interactions of the Cloudy Arctic Boundary Layer with Variable Surface Conditions and Large-Scale Circulations

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。科罗拉多州立大学的研究人员将改进平流层云对北极地表热收支影响的计算机模拟。开放水域的比例、冰的厚度、积雪覆盖/厚度和融化池覆盖/厚度将被用来研究这些参数对云形成的影响。改进北极气候模式中的云分量模拟对于提高用于检验可能的温室效应对全球气候的全球气候模式的准确性至关重要。?？

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 Colorado State University will improve computer simulations of the effect of Stratus clouds on the surface heat budget of the Arctic. The fraction of open water, ice thickness, and snow cover/thickness, and melt pond cover/thickness will be used to look at the effect of these parameters on cloud formation. The improvement of the cloud component simulations in Arctic climate models is essential to improving the accuracy of global climate models used to examine possible greenhouse effects on global climates. ??
