摘要: Reverse-trajectory calculations initialized with ozone observed by the Upper Atmosphere Research Satellite Microwave Limb Sounder (MLS) provide high-resolution profiles for comparison lidar and ozonesonde observations from Arctic Stratospheric Observatory facility near Eureka in Canadian (∼80°N, 86°W). By statistical measures, calculated show a small average improvement over MLS agreement of small-scale structure that ground-based throughout stratosphere, larger (although still modest) more consistent lower stratosphere. Nearly all daily gridded data some Even cases where overall between is mediocre, there are frequently one or individual features strongly resemble laminae observations. Differential advection large-scale winds leads to lamination three distinct ways. Filamentation results comparable arising initializations potential vorticity/θ-space reconstructions (reconstructed (RC) fields). Laminae also form middle stratosphere conjunction intrusions into vortex; while RC fields produce laminae, using initialization distinctly better. Inside stratospheric vortex, local fields; RC-initialized fail any significant since these variations not correlated vorticity. That needed resembling those independent at indicates both datasets capturing real atmospheric features.
