Air-sea exchange of semivolatile organic compounds ? wind and/or sea surface temperature control of volatilisation studied using a coupled general circulation model

Popis výsledku v původním jazyce

The global multicompartment chemistry-transport model MPI-MCTM is used to determine the sensitivity of volatilisation of dichlorodiphenyltrichlorethan (DDT) and dichlorodiphenyldichloroethylene (DDE) to SST and wind speed changes. Parameters controllingthe volatilisation of DDT from the ocean surface, none of them independent, and their degree of control are identified and mapped by a correlation analysis on the seasonal time scale and by an empirical orthogonal functions (EOF) analysis on the inter-annual timescale. Seasonal variations of volatilisation are shown to be controlled by either wind speed or SST in different sea regions. On this time scale wind is more dominant than SST in the global ocean. The main pattern of inter-annual variability (upto decades), however, is shown to be explained by SST. The results suggest that large-scale spatial averaging, including zonally averaging leads to underestimates of the volatilisation rate and the long-range transport potential of SOCs.
