| Research Abstract |
Tropical stratosphere.troposphere coupling is investigated by analyzing recently obtained advanced satellite data. It was found that meridional circulation associated with stratospheric sudden warming affects not only the formation of cirrus cloud and deep convection but also their large-scale organization. The stratosphere is conventionally considered to react passively to the troposphere ; however, the present results demonstrate the need to consider stratosphere. troposphere interaction in studies of weather and climate in the troposphere.
