Abstract

Here the focus is on the climatological pathway of airflow to the Atmosphere/Ocean Chemistry Experiment sites, determined by superposition of ensembles of isentropic trajectories. At Bermuda there is a notable seasonal variation, with the months of May-November dominated by flow around the subtropical anticyclone, while flow from the northwest and west is more common in the cooler months of December-April. Flow from the west predominates at Mace Head, Ireland, in the months from April-September, while flow from the east (over Great Britain and western Europe) is of increased importance during October-March. At Izana the flow is most commonly from the west; flow from the east, over Africa and southern Europe, is most common during the months of July-September. The winds at Barbados, West Indies, are much steadier than at the other sites, and there is little seasonal variation in the general pattern of flow. -from Author
