60-Year Decline In Winter Rains Over Iberian Peninsula: Scientists Project Other Seasonal Drops

[hatrack]

Scientists have recorded a decline in winter precipitation over the past 60 years in Spain, and they now forecast that precipitation will also decrease in spring and summer.

A team from the Pyrenean Institute of Ecology (CSIC) has studied rainfall data from 1950 to 2006 and the climate projections for coming decades, showing that less rain will fall in future over the Iberian Peninsula. However, precipitation will continue to be more frequent in winter than in spring-summer.

Have there been any changes to the monthly contributions to total annual precipitation within the Mediterranean basin? Researchers from the Pyrenean Institute of Ecology (CSIC) have assessed the changes observed in rainfall patterns since 1950, and are predicting contributions to be lower by the middle of the 21st Century, against a backdrop of increasing greenhouse gas emissions.

"We have used the data reported (1950-2006) and simulated various climate models (2040-2060) to look at whether the monthly contribution to the annual total has changed over recent decades, and whether such changes are likely to happen over the medium term", Juan Ignacio Lopez-Moreno, lead author of the study, tells SINC. The research, published recently in the journal Geophysical Research Letters, studied variability and climate change in the Mediterranean region.
