Among the different meteorological hazards, droughts are those with the
highest socio-economical impact on the Iberian Peninsula. Drought events
have been largely studied in the instrumental period, but very little is
known about the characteristics of droughts in the preinstrumental period.
In this work, several series of rogation ceremonies are used to identify
severe droughts within the period 1750–1850. The overlapping of the rogation
series with some instrumental series served to identify some climatic
characteristics of rogation ceremonies: (a) during spring, rainfall deficits
needed to celebrate rogation ceremonies are smaller than in any other
season; (b) the hydrological deficit in a particular region increases with
the number of locations celebrating rogations simultaneously.
On the other hand, it was found that between 1750–1754 and 1779–1783 are
probably the driest periods of the 101 analyzed years. Both show an
important number of rogations all over Iberia and during all the seasons.
The most extended drought of this period occurred during the spring of 1817,
affecting 15 of the 16 locations studied. This drought was influenced by the
Tambora eruption (1815). The study of the climate footprint of this eruption
and its comparison with similar situations in the series suggest that the
spring drought of 1824 may be associated with the eruptions of the
Galunggung and Usu volcanoes (1822). Further studies are required to confirm
this fact and understand the atmospheric mechanisms involved. |
