The objective of this research project is to examine how well the National Center for Atmospheric Research's Community Climate Model treats the planetary distribution of heating in its climate simulations. A series of sophisticated diagnostic tools will be employed by the PI who is a world leader in this kind of research. Proper specification of heating distributions are of great importance in climate modeling and so this research treats a subject primary to advancements in climate understanding and prediction. Heat energy from the sun is received at the earth's surface and within the earth's atmosphere non-uniformly in space, in particular from equator to poles, but also around a latitude circle because of ocean and land distributions. Our weather and climate respond to these distributions in solar heating. In order to successfully simulate and predict climate in computer models one must represent them in terms of heating functions as accurately as possible. For model simulation and prediction of climate this is a necessary first step. It is also a difficult task because of the non-linear interactions between solar radiation and atmospheric moisture and trace gases, surface boundary conditions, and ultimately terrestrial radiation retransmitted to the atmosphere and to space. Research of this kind is key to understanding the climate system.

这个研究项目的目的是检验国家大气研究中心的社区气候模型在其气候模拟中如何很好地处理加热的行星分布。PI将使用一系列复杂的诊断工具，PI是这类研究的世界领导者。在气候模拟中，热分布的适当规范是非常重要的，因此本研究主要关注气候理解和预测的进展。来自太阳的热能在地球表面和地球大气层内的空间接收不均匀，特别是从赤道到两极，但由于海洋和陆地的分布，也会在纬度圈周围接收。我们的天气和气候在太阳能加热中对这些分布作出反应。为了在计算机模型中成功地模拟和预测气候，必须尽可能准确地用加热函数表示它们。对于模式模拟和气候预测来说，这是必要的第一步。这也是一项艰巨的任务，因为太阳辐射与大气水分和微量气体、地表边界条件以及最终重传到大气和空间的地面辐射之间存在非线性相互作用。这类研究是了解气候系统的关键。
