| Zusammenfassung |
| Climatic variability from the beginning of regular meteorological observations is now
acknowledged. However, climate change prior to 1900 is far from being well known in
Portugal, except for the 1675-1800 period in Southern Portugal. An interdisciplinary team is
working in the frame of the KLIMHIST PROJECT (“Reconstruction and model
simulations of past climate in Portugal using documentary and early instrumental sources,
17th-19th century)”, since May 2012. The main objectives of the project are: (i) to
contribute to the creation of a long-term history of climate in Portugal by producing
databases of documentary evidence and of instrumental data since 1645, a period of
natural climate variability that includes the Maunder Minimum and the Dalton
Minimum; (ii) to search systematically for the first simultaneous documentary and
instrumental data in order to calibrate the series; (iii) to analyse simulated multi-decadal
trends over Portugal generated by climate models; (iv) to compare results with
those obtained from dendroclimatology and from geothermal studies regarding
Portugal and (v) to study extreme events of the past, their impacts and the vulnerability
of societies to weather during the last 350 years, and compare them with current
analogues.
With these tasks, we expect to help completing the spatial coverage of past European
climate, as the data gap over SW Europe is often mentioned.
As the team members come from four different Universities in Portugal (Évora, Lisbon,
Oporto and UTAD), we expect to obtain a good spatial representation of documentary
evidence. Teams are now progressing in data search activities in archives. An Access
database frame was constructed. Some 18th century extreme events have been and are being
studied (Barbara storm, Dec.1739, among others). The first workshop took place in Lisbon
(October 2012): Prof Brázdil and Dr. Domínguez-Castro (two of our consultants) were
keynote speakers.
