Eddy Heat Transports in the Atmospheres of Earth and Mars

9816238 barnes大气经向热输运在地球和火星的气候系统中都起着中心作用，有助于调节南北温差。巴恩斯博士将使用简化大气环流模型（GCM）的数值实验来研究涡旋热输送及其在确定纬向平均经向温度梯度中的作用。这些结果将对地球和火星瞬态涡旋机制之间的差异提供相当大的启示，并有助于更好地理解涡旋热输运如何调节两种大气中的经向热梯度。了解这一点对于评估两颗行星在更长时间尺度上的气候变化的影响非常重要。这个项目的经费由天文科学司和数学和物理科学局的多学科活动办公室分担。＊＊＊

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.
