Estimation of transboundary air pollution on the basis of synoptic‐scale weather typesNARA Subscribed
International Journal of Climatology · 2003 · Vol. 23 · Issue 4 · Wiley

A methodology to estimate annual transboundary atmospheric transport is proposed, taking into account different background meteorological conditions. For this purpose, the 850 hPa synoptic‐scale atmospheric circulation over the area examined was classified on a daily basis into 14 distinct synoptic types, using a database for an extended period of 40 years. The corresponding frequency of appearance of the synoptic types for a...
