Dynamic Meteorology

Lindzen博士将继续研究动态气象学，气候动力学和地球物理流体动力学的各种主题。 具体而言，他将（1）研究位涡混合与辐射强迫和Hadley环流动力学在确定大气层纬向温度分布方面的作用;（2）进一步探索引力潮汐在外行星上的作用;（3）扩大对 （4）继续研究对流层上层水汽收支及其参数化;（5）研究末次冰期期间主要冰盖强迫的定常波及其在观测到的快速气候变化中的作用;（6）研究当Rossby波的涡度拟能超过平均涡度拟能时，流体对饱和Rossby波的非线性调节;（7）研究Orr机制对辐射波包的激发;（8）确定斜压不稳定流的两层非线性模式的超临界平衡是否由正压稳定化来解释。 水蒸气研究将与海洋-陆地-大气相互作用中心（COLA）和COLA GCM的科学家合作进行;其他研究将使用不同复杂性的机械模型进行。 所有这些研究将有助于更好地了解天气和气候的基本物理学以及行星大气的动态。 水汽研究将有助于实现云、能量和水在全球气候变化计划中的作用的目标。

Dr. Lindzen will continue research on a variety of topics in dynamic meteorology, climate dynamics, and geophysical fluid dynamics. Specifically, he will (1) examine the roles of potential vorticity mixing in conjunction with radiative forcing and Hadley circulation dynamics in determining the atmosphere's meridional temperature distribution; (2) further explore the role of gravitational tides on the outer planets; (3) expand a study of this process in the Milankovich mechanism; (4) continue studies of the upper tropospheric water vapor budget and its parameterization; (5) investigate the stationary waves that were forced by the major ice sheets during the last glaciation and their role in observed rapid climate changes; (6) study the nonlinear accommodation of a fluid to the saturation of Rossby waves when their enstrophy exceeds the available mean enstrophy; (7) study the excitation of radiating wave packets by the Orr mechanism; and (8) determine whether barotropic stabilization accounts for the supercritical equilibration of two-level monlinear models of baroclinically unstable flows. The water vapor studies will be conducted in collaboration with scientists from the Center for Ocean-Land- Atmosphere Interaction (COLA) and COLA GCM; the other studies will be conducted mechanistic models of varying complexity. All of these studies will contribute to better understanding of the basic physics of weather and climate and the dynamics of planetary atmospheres. The water vapor studies will contribute to the goals of the Role of Clouds, Energy, and Water in Global Climate Change Program.
