| 内容記述 | The mechanism of heat transport in geostrophic flows under various density stratifications has been studied by using both direct numerical simulation and rapid distortion theory. It is found that in cases with rotation, the iso-surfaces of the temperature fluctuations are aligned in the direction of the rotational axis, and they become very close to two-dimensional. Under stable stratification with rotation, the velocity and temperature fluctuations tend to oscillate with the Brunt-Vaisala frequency, while they tend to oscillate with a longer period in cases without rotation. Under unstable stratification with rotation, on the other hand, vortex columns are formed in the direction parallel to the axis of rotation owing to the effects of nonlinear interactions. | |||||||||
