SYNOPTIC VARIABILITY RELATED TO BOUNDARY-LAYER AND SURFACE-FEATURES OBSERVED DURING PACIFIC-93

Datasets collected during Pacific '93 enable us to construct a three-d imensional view of the atmosphere over the Fraser Valley (southwest Br itish Columbia), and to examine relationships between conditions aloft and those in the boundary layer. Herein, vertical and horizontal prof iles of the atmosphere obtained from a ground based Doppler lidar are examined in conjunction with data from an airborne downward looking li dar, meteorological soundings of temperature and wind profiles, synopt ic charts and surface pressure analyses. These data sets aid understan ding of the flow structure at a number of levels through the boundary layer and the spatial and temporal variability of topographically-indu ced flow.
