The extremely atmospheric events such as typhoon can largely and rapidly change the sea conditions, producing giant surface waves, strong turbulent mixing, inertial oscillations, and cold wake in a ~10^5 km^2 area in the upper ocean. The cold wake could persistent several weeks. The typhoons grow in the ocean by extracting the ocean heat content. Aside from the observed atmospheric condition, the input of the thermal structure in the upper 100-200 m and its corresponding upper ocean heat content as the boundary condition in the forecasting model could significantly improve the model performance. This project aims to improve the capability of typhoon observation in the ocean to understand the impact of typhoon on the upper ocean and, consequently, to improve the typhoon forecasting. The scientific and technical goals are: (1) to understand the mechanisms, processes, and impacts of turbulent mixing in the upper ocean during the extreme wind speed, (2) to quantify the flux of momentum and heat, (3) and to improve the technology of surface data buoy observation to accomplish the above scientific goals.颱風冷尾跡慣性震盪紊流混合typhooncold wakeinertial oscillationsturbulent mixing
