Abstract
In October 1970 the South China Sea experienced three typhoons. Meteorological and oceanographic data were examined in an attempt to explain why the typhoons underwent intensity changes while over the South China Sea. The clearest relationship was found with troughs in the upper tropospheric westerlies—intensification accompanied development of a middle and high cloud plume streaming northeastward from the storm area.
