| Zusammenfassung |
| Precipitation and desert dust event occurrence time series measured in the
Canary Islands region are examined with the primary intention of exploring
their scaling characteristics as well as their spatial variability in terms
of the island's topography and geographical orientation. In particular, the
desert dust intrusion regime in the islands is studied in terms of its
relationship with visibility. Analysis of dust and rainfall events over the
archipelago exhibits distributions in time that obey power laws. Results show
that the rain process presents a high clustering and irregular pattern on
short timescales and a more scattered structure for long ones. In contrast,
dustiness presents a more uniform and dense structure and, consequently, a
more persistent behaviour on short timescales. It was observed that the
fractal dimension of rainfall events shows an important spatial variability,
which increases with altitude, as well as towards northern latitudes and
western longitudes. |
