Summary
The atmosphere adjacent to the ground is called the atmospheric boundary layer. It plays an important role in interactions between Earth’s surface and the atmosphere. Air flow in the boundary layer can be turbulent, which is difficult to model. Nevertheless, the success of weather models depends critically on accurate representations of the boundary layer. Current models do not account for large, organized, rolling air currents that strongly affect flow inside the boundary layer. Most studies of these organized rolling motions, which are called coherent structures, are based on laboratory
