This is a theoretical project to calculate three-dimensional models of brown dwarf interiors and atmospheres, where rotation and convection are included, as well as the interaction between the interior and overlying stratified atmosphere. The model will address observational data which are consistent with the presence of clouds, chemical disequilibrium, and temporal variability. The research will predict infrared spectra, lightcurves and vertical mixing rates for comparison with observations, including directly imaged giant extrasolar planets.Broader impacts include training a graduate student for his or her Ph.D., incorporating the numerical code in the graduate and undergraduate courses that the PI teaches, and dissemination of the results to the scientific community and general public.

这是一个计算褐矮星内部和大气的三维模型的理论项目，其中包括旋转和对流，以及内部和上层分层大气之间的相互作用。 该模型将处理与云的存在、化学不平衡和时间变化相一致的观测数据。 这项研究将预测红外光谱、光变曲线和垂直混合率，以便与观测结果进行比较，包括直接成像的巨大太阳系外行星。更广泛的影响包括培养一名研究生攻读博士学位，将数字代码纳入PI教授的研究生和本科生课程，并将结果传播给科学界和公众。
