Variation of pCO(2) concentrations induced by tropical cyclones “Wind-Pump” in the middle-latitude surface oceans: A comparative study
The Bermuda Testbed Mooring (BTM) and Bay of Bengal Ocean Acidification (BOBOA) mooring measurements were used to identify changes in the partial pressure of CO(2) at the sea surface (pCO(2sea)) and air-sea CO(2) fluxes (F(CO2)) associated with passage of two tropical cyclones (TCs), Florence and Hu...

The Bermuda Testbed Mooring (BTM) and Bay of Bengal Ocean Acidification (BOBOA) mooring measurements were used to identify changes in the partial pressure of CO(2) at the sea surface (pCO(2sea)) and air-sea CO(2) fluxes (F(CO2)) associated with passage of two tropical cyclones (TCs), Florence and Hudhud. TC Florence passed about 165 km off the BTM mooring site with strong wind speeds of 24.8 m s(–1) and translation speed of 7.23 m s(–1). TC Hudhud passed about 178 km off the BOBOA mooring site with wind speeds of 14.0 m s(–1) and translation speed of 2.58 m s(–1). The present study examined the effect of temperature, salinity, dissolved inorganic carbon (DIC), total alkalinity (TA), air-sea CO(2) flux, and phytoplankton chlorophyll a change on pCO(2sea) as a response to TCs.
