Days with PPT ≥ 20 mm (R20)
Days with PPT ≥ 20 mm (R20): annual count of days when daily precipitation is equal or greater than 20 mm (PPT ≥ 20 mm). The unit of measurement is days.
The evolution of R20 anomaly (AR20, difference between the annual value of R20 and the mean value of R20 in the reference period 1981-2010) during the period 1959-2020 is shown for the Pyrenees and for 4 areas of the Massif (Northern Pyrenees, Southern Pyrenees, Mediterranean Pyrenees and Atlantic Pyrenees); for each of the 26 series analyzed, the evolution of R20 index is shown.
The annual mean of R20 for the Pyrenees is obtained from the annual R20 values of 26 representative series of the Pyrenees massif (areas at different altitudes and on all slopes: north, south, east or Mediterranean and west or Atlantic), while the mean value of R20 for the 4 zones of the Massif is obtained from the annual R20 values of the representative series located in each zone.

Evolution of the annual R20 anomaly (AR20, in days) in the Pyrenees for the period 1959-2020. Green points (positive AR20) indicate a R20 value higher than the reference period value and orange points (negative AR20) indicate a R20 value lower than the reference period value.
The dotted line shows the linear trend of the series (-0,2 days/decade).

Bulletin of Climate Change Indicators of the Pyrenees 2020
The Bulletin of Climate Change Indicators of the Pyrenees (BICCPIR) 2020 aims to deepen the knowledge of the anthropic climate change effects in the Pyrenees. Thus, information on the climate evolution is provided through a set of indicators grouped by systems.
