Abstract

The exploration and research of ocean turbulence is very important to understand the operational mechanism of ocean circulation, to improve simulation and prediction ability of the global climate changes and circulation. At present, the turbulence instrument includes two types: horizontal turbulent measurement platform and vertical turbulent profiler. In the two types of instrument, the main noise sources are vibrations of platform. And the vibration signal directly affects the quality of turbulence detection. According to the basic principle of turbulence detection, a turbulent data processing method based on pseudo dissipation rate is proposed. This method can improve the intelligent degree of turbulence detection. Compared with turbulent kinetic energy dissipation rate in orders of magnitude, this method can help to find effective turbulence signal. By using the actual observation data, we have verified that method is effective, which verified.
