9816238巴恩斯大气纬向热传输在地球和火星的气候系统中起着核心作用，有助于调节南北温差。 巴恩斯博士将利用简化的大气环流模式（GCM）进行数值试验，研究涡旋热输送及其在确定纬向平均纬向温度梯度方面的作用。 结果应该相当亮的差异之间的陆地和火星瞬态涡流制度，并有助于更好地从根本上了解如何涡流热传输的行为，以调节在两个大气层中的对流热梯度。 了解这一点对于评估两颗行星在较长时间尺度上气候变化的影响非常重要。该项目的资金由天文科学处和数学和物理科学局多学科活动办公室共同提供。***

9816238BarnesAtmospheric meridional heat transport plays a central role in the climate systems of both Earth and Mars, helping to regulate the north-south temperature difference. Dr. Barnes will use numerical experiments with a simplified atmospheric General Circulation Model (GCM) to investigate eddy heat transports and their role in determining the zonal-mean meridional temperature gradient. The results should shed considerable light on the differences between the terrestrial and Martian transient eddy regimes, and contribute to a better fundamental understanding of how eddy heat transport acts to regulate the meridional thermal gradient in the two atmospheres. Understanding this is important to assessing the effects of climatic variations on longer time scales for both planets.
