Lindzen will continue his research on a broad set of problems in dynamic meteorology which follow from studies conducted under his previous grant. Five specific topics for further research over the next three years are planned: (1) a special hydrodynamic mechanism that may allow energy extracted from a region of shear flow to be transported away by waves, (2) gravitational tides on Jovian planets, (3) a possible cause of the 100,000-year quasi- periodicity of ice ages, (4) a new procedure to produce initial data for numerical weather forecasts, and (5) the role of the water vapor budget of the upper troposphere in climate and climate change. His research on the first topic could uncover a process essen- tial in shaping the atmospheric general circulation. The atmo- spheres of other planets, or the paleoclimatology of ours, are so remote in space and time that these studies might appear, superfi- cially, to be only of pedagogical and theoretical interest. They will, however, add to our body of knowledge and understanding of the behavior of planetary atmospheres. Lindzen is a member of the National Academy of Sciences and, arguably, the leading present-day dynamic meteorologist. His continued attention to refining the sys- tem that produces our routine, daily computerized weather forecasts serves as an example to the younger members of the research community in atmospheric sciences. He has also been an outspoken public critic of the global warming numbers calculated by the present generation of climate models. He bases his skepticism on their imprecise treatment of the feedbacks linking water vapor, cloud, and solar and terrestrial radiation. Improving this aspect of the models is generally acknowledged to be one of most challenging problems in climate science, and has the highest research priority in science planning and policy. With his work on the final topic he will contribute to intensified international efforts on the quantitative specification of these links.

Lindzen将继续对动态气象学的广泛问题进行研究，这是他先前赠款所进行的研究。 Five specific topics for further research over the next three years are planned: (1) a special hydrodynamic mechanism that may allow energy extracted from a region of shear flow to be transported away by waves, (2) gravitational tides on Jovian planets, (3) a possible cause of the 100,000-year quasi- periodicity of ice ages, (4) a new procedure to produce initial data for numerical weather forecasts, and (5) the role of the water气候变化和气候变化中对流层上层的蒸气预算。 他对第一个主题的研究可能会发现塑造大气一般循环的过程。其他行星的大气或我们的古气候学在时空和时间上是如此遥远，以至于这些研究可能会出现，从而仅具有教学和理论上的兴趣。但是，他们将增加我们对行星气氛行为的知识和理解。林岑（Lindzen）是美国国家科学院（National Science）的成员，可以说是当今的领先动态气象学家。他继续关注完善我们日常的，每天计算机化天气预报的系统，这是大气科学研究界的年轻成员的榜样。他还一直是对当代气候模型计算出的全球变暖数字的直言不讳的公众批评者。他对将水蒸气，云以及太阳辐射和陆地辐射联系起来的反馈的不精确处理对待了他的怀疑。通常认为改善模型的这一方面是气候科学中最具挑战性的问题之一，并且在科学规划和政策中具有最高的研究优先事项。在他在最后一个主题方面的工作，他将为这些链接的定量规范加强国际努力做出贡献。
