Hsin-I Lin is a master’s student at the Institute of Oceanography, National Taiwan University, Taiwan, under the supervision of Prof. Yiing-Jang Yang. Her research focuses on using buoy observations to investigate turbulent mixing in the northwestern subtropical Pacific Ocean.
The work presented at EGU 2023 discusses turbulent mixing during the passage of Typhoon Hinnamnor (2022) and a mesoscale cold eddy by estimating the Richardson number at depths of 20 and 75 m. The observation results during the passage of Typhoon Hinnamnor indicate that the peak of the Richardson number in the probability distribution was below a critical value of 0.25 at a depth of 20 m, implying strong mixing, and typhoon-induced turbulent mixing occurred at depths shallower than 75 m. Furthermore, during the cold eddy period, the stratification became more stable at a depth of 20 m, resulting in an increase in the Richardson number, which suppressed turbulent mixing.
