lamination in the tropical stratosphere

Climate change might alter stratospheric transport processes which in turn could influence the Earth's protective ozone layer. Detailed knowledge of these transport processes is critical to predicting the potential response of the ozone layer to a changing climate. Even though there is convincing evidence for entrainment of mid-latitude air into the tropical stratosphere, the mechanistic and dynamical details of the transport process are poorly understood. Single events of laminae within the tropical pipe have been reported and are potentially responsible for the entrainment. We report on the analysis of laminae in tropical ozone soundings from the years 1998-2001. Additonally, we present our investigation of using wavelet analysis to detect laminae in satellite data sets. These data sets usually don't have the altitude resolution necessary to detect the thin laminae observed in in-situ data sets.
