Fundamental laboratory experiments will be performed to study the development of internal waves and the transition to turbulence in uniform sheared and stratitied flow. Techniques are developed by which both the velocity shear and the density gradients can be measured with sufficient accuracy to determine a significant range of Richardson numbers. These measurements will be used to investigate the details of internal wave breaking, and other mechanisms of instability, and also to test fundamental theoretical ideas developed by mathematicians and numerical modelers.

将进行基础实验室实验，以研究 内波的发展和向湍流的转变 均匀剪切流和分层流。 技术的发展， 速度剪切和密度梯度都可以用 足够的精度来确定理查森的显著范围 号码 这些测量结果将用于调查以下细节： 内部波浪破碎和其他不稳定机制，以及 来检验数学家发展的基本理论， 数字模型。
