A global blended tropopause based on ERA data . Part I : Climatology

  title={A global blended tropopause based on ERA data . Part I : Climatology},
  author={Laura J. Wilcox and Brian J. Hoskins and K. P. Shine},
A new tropopause definition, based on a flow-dependent blending of the traditional thermal tropopause with one based on potential vorticity, has been developed. The benefits of such a blending algorithm are most apparent in regions with synopticscale fluctuations between tropical and extratropical air masses. The properties of the local air mass determine the relative contributions to the location of the blended tropopause, rather than this being determined by a specified function of latitude… CONTINUE READING
