| Zusammenfassung |
Hail is a serious concern for agriculture on the Iberian Peninsula.
Hailstorms affect crop yield and/or quality to a degree that depends on the
crop species and the phenological time. In Europe, Spain is one of the
countries that experience relatively high agricultural losses related to
hailstorms. It is of high interest to study models that can support
calculations of the probabilities of economic losses due to hail damage and
of the tendency over time for such losses.
Some studies developed in France and the Netherdlands show that the summer
mean temperature was highly correlated with a yearly hail severity index
developed from hail-related parameters obtained for insurance purposes.
Meanwhile, other studies in the USA point out that a highly significant
correlation between both is not possible to find due to high climatic
variability.
The aim of this work is to test the correlation between average minimum
temperatures and hail damage intensity over the Spanish Iberian Peninsula.
With this purpose, correlation analyses on both variables were performed for
the 47 Spanish provinces (as individuals and single set) and for all crops
and four individual crops: grapes, wheat, barley and winter grains. Suitable
crop insurance data are available from 1981 until 2007 and based on this
period, temperature data were obtained.
This study does not confirm the results previously obtained for France and
the Netherlands that relate observed hail damage to the average minimum
temperature. The reason for this difference and the nature of the cases
observed are discussed. |
