Influence of Noul Typhoon on Sea Surface Temperature, Heat Fluxes and Precipitation Rate

This paper presents how a typhoon can change the sea surface temperature (SST) and heat fluxes trend. As a case study, Noul typhoon was investigated over the South China Sea. It affected South China Sea from November 14 to November 17 in 2008. Using archived data of National Centers for Environmental Prediction / National Center for Atmospheric Research data set, the effects of Noul typhoon on SST, latent heat flux (LHF), and sensible heat flux (SHF), were studied. Furthermore, the precipitation rate (Prate) during the typhoon was investigated as well. As a contribution, comparing daily and monthly contour maps for the desired parameters showed the important variations which resulting from typhoon intensity. The results also indicated that SST decreased in the area (SST contours occupy a smaller area) and Heat Fluxes reduced during the storm as well, from range of 100-300 W/m 2 to 80-140 W/m 2 . The parameters must remain in a special range (shown in the figures, at least 302 oK for SST and 90 and 10 W/m 2 for LHF and SHF respectively), to help the storm to be alive and grow. Results indicate that the amount of Prate is also affected by the storm’s severity.
