Résumé

The aim of this work was to analyze statistically the atmospheric particle number size distributions, at the sampling station El Arenosillo located at the southwest of Spain, in terms of their relation to meteorological parameters. With this purpose, surface wind data and submicrometric particle size distributions were collected over one year period. According to the main wind directions the studied zone may be divided in two areas: polluted and nonpolluted areas, with (7,106 ± 281) cm−3 and (5,623 ± 400) cm−3, respectively. From the wind database patterns of de sea–land breeze have been identified at El Arenosillo. The relationship between the breeze and the particle number size distributions was analyzed. The average diurnal total concentration showed the greater value with no pure sea–land breeze with synoptic wind forcing from north with (8,683 ± 2,240) cm−3. The results in the case of pure breeze and breeze with synoptic wind forcing from south were an inferior 26% and 12%, respectively. Short time events with high concentrations were identified during local recirculations. They were called Events by Breeze. As regards the wind speed, high concentrations of nucleation and Aitken modes particles were observed during spring time, with low wind velocities. This condition favors the photochemical mechanism leading to the formation of new aerosol particles.
