        大气运动的非线性不稳定与稳定性 ,分别与天气的剧烈变化和持续性异常密切相关 ,其研究是数值天气预报、短期气候预测的基础 ,属于大气科学、地球流体力学与非线性科学的交叉学科领域。我们将能量 Casimir方法与现代非线性偏微分方程理论中的非线性先验估计方法有创新性地结合起来 ,在该领域取得了突出的成果。该成果获 2 0 0 1年中国科学院自然科学奖一等奖

        This paper is an introduction to the study on nonlinear stability and instability of atmospheric motions, which is closely related to the weather’s drastic changes and persistent anomaly. It is the interdisciplinary study of atmospheric science, geophysical fluid dynamics and nonlinear science, which provides the basis of numerical weather and short term climate prediction and is also the frontier that is developing fast in atmospheric sciences. The author and his research group have combined the Energy Casimir method with the a prior estimate method innovatively and have attained outstanding achievements. The results won the first class prize of natural science of Chinese Academy of Sciences (2001).
