Stratified turbulence in the troposphere and stratosphere is inherently episodic and inhomogeneous, fundamentally challenging attempts to understand, predict, and parameterize its behavior and impacts. It plays an important role in index-of-refraction fluctuations that affect laser communication and laser sighting systems. In this talk I describe simulations we are currently conducting of canonical atmospheric shear- and gravity-wave-induced turbulence processes, both separately and in combination, in an attempt to develop parameterization schemes for larger-scale models that cannot resolve their detailed dynamics.
