摘要：

The inorganic chemical composition of settling particles from 10 dust storms in Hamad Town, Bahrain has been determined. These storms occurred over a 3-year period. Meteorological conditions during the storms were examined and the storms classified, according to their trajectories, into two types: (a) a low pressure system from the Mediteranean, which traveled east into the Gulf and caused periods of disturbed weather and causing of north-westerly winds; and (b) a low pressure over Pakistan causing dry north-westerly wind, known locally as Al-Barah. After this period, the low pressure system declined allowing the formation of south-easterly winds known as the Kaus. The composition of the dust storms is montonic. The settling particles are relatively enriched in Ca 2+, K+ and SO42- derived from local soil, and Cl- from the sea.
