✦ Synopsis

Two errors in the Kirchhofer technique of synoptic typing are revealed. The first error interferes with the attempt to ensure that grids classified as similar are sufficiently similar at the sub-grid level. The second, and less important, error involves the conversion of Kirchhofer scores to correlation coefficients. The consequences of these errors are demonstrated by comparing the results of two classifications, one with the errors included, one with the errors removed. The classification based on the original algorithm allows many grids to be classified as similar even though they are not (as defined by the user's similarity thresholds). The classification based on the corrected algorithm produces results that might not be acceptable to climatologists attempting to summarize a region's synoptic regime with a small number of synoptic types.

The Kirchhofer technique for identifying spatial patterns in climate data depends on the threshold and minimum size used to define the groups. As a result, the analyst cannot be sure whether the groups defined by the Kirchhofer technique represent meaningful meteorological phenomena or whether they

## Abstract 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 disti
