Abstract

A 6-yr climatology of routine surface meteorological reports of dust in Asia is used to examine the broad maximum in mineral dust concentrations in the months February-May observed at all the North Pacific sites. The gross features of this seasonal variation are controlled by the occurrence and areal extent of dust outbreaks. Secondary peaks in the frequency of dust storms in October-December, correspond to isolated peaks in the dust concentration at the sites closest to the mid-latitudes. Isentropic trajectory analyses are presented for individual events of peak concentrations supporting earlier indications that the dust transport begins at high elevations over the arid regions and gradually subsides for those parcels which move toward the south. -from Authors
