Diagnostic Analysis of Wind Observations Collected during the Southern CaliforniaAir Quality Study

摘要

Wind data collected during eight intensive monitoring periods in the 1987Southern California Air Quality Study (SCAQS) were used to analyze the mesoscale airflow patterns in the South Coast Air Basin (SOCAB). The SCAQS data base contains the most comprehensive set of surface and upper-air wind data ever assembled for the SOCAB. The data set represents good spatial and temporal resolution of some mesoscale airflow features. The wind data were analyzed using a diagnostic wind model. The analysis consisted of (1) generation of hourly, gridded wind fields for the 17 SCAQS intensive study days, (2) analysis of the mesoscale airflow patterns, and (3) calculation of forward and backward particle trajectories to examine pollutant transport in the SOCAB.
