| Zusammenfassung |
| The aim of this study is to analize the influence of wind (speed and direction) on the daily
airborne pollen counts recorded in Catalonia (NE Iberian Peninsula) of 21 pollen
taxa recorded at 6 aerobiological stations: Barcelona, Bellaterra, Girona, Lleida
Manresa, and Tarragona for the period 2004-2014. The taxa studied are Alnus,
Betula, Castanea, Cupressaceae, Fagus, Fraxinus, Olea, Pinus, Platanus, total
Quercus, Quercus deciduous type, Quercus evergreen type, Ulmus, Corylus, Pistacia,
Artemisia, Chenopodiaceae/Amaranthaceae, Plantago, Poaceae, Polygonaceae, and
Urticaceae.
The mean daily wind direction was divided into 8 sectors: N, NE, E, SE, S, SW, W and
NW. For each sector, the correlation between the daily pollen concentrations and wind speed
using Spearman’s rank correlation coefficient was computed and compared with the
wind rose charts. The results showed that Tarragona was the station with more
significant correlations followed by Bellaterra, Lleida and Manresa. On the other
hand, Artemisia was the most correlated taxon with mainly negative values, and
Fagus was the least. The W wind direction showed the largest number of significant
correlations, mostly positive, while the N direction was the least and negatively correlated. |
