Evaluation of the Regulation and Response of Ocean Heat Content to Typhoons in the Northwest Pacific Based on GDCSM_Argo
The Northwest Pacific is a source of strong typhoons accompanied by significantly changing ocean heat content (OHC). Based on the GDCSM_Argo dataset, all typhoons within twenty years are considered to explore the regulation of OHC between 0 and 2000 m with typhoons in this study. The results show a...

| description | The Northwest Pacific is a source of strong typhoons accompanied by significantly changing ocean heat content (OHC). Based on the GDCSM_Argo dataset, all typhoons within twenty years are considered to explore the regulation of OHC between 0 and 2000 m with typhoons in this study. The results show a weak correlation between OHC and typhoons but a strong correlation between ocean heat content uptake anomaly (OHUA) and typhoons by wavelet, lag/lead, and EOF analyses. The energy reserve effect by the OHUA on typhoon generation is most significant at a 3-month lag. The OHUA above 300 m primarily influences typhoons’ temporal and spatial characteristics. On the other hand, typhoons enhance vertical transmission of OHC through entrainment. A modified version of the Richardson number (R<sub>ohc</sub>) is used for the characterization of the hydrostatic stability between ocean layers. The entrainment is particularly strong in the Northwest Pacific north of 20° N, where R<sub>ohc</sub> is between −0.2 and 0. The OHC below the mixed layer also responds to typhoon disturbances but transports less heat vertically than the near-surface layers. Our results suggest that GDCSM_Argo provides reliable data support for the study of the relationship between OHC and typhoons. |
