Warm days (TX90p)
Warm days (TX90p): annual percentage of days with a maximum temperature (TX) greater than the 90th percentile of the daily TX series for the base period 1981-2010. The unit of measurement is %.
The evolution of TX90p anomaly (ATX90p, difference between the annual value of TX90p and the mean value of TX90p 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 12 series analyzed, the evolution of TX90p index is shown.
The annual mean of TX90p for the Pyrenees is obtained from the annual TX90p values of 12 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 TX90p for the 4 zones of the Massif is obtained from the annual TX90p values of the representative series located in each zone.

Evolution of the annual TX90p anomaly (ATX90p, in %) in the Pyrenees for the period 1959-2020. Red points (positive ATX90p) indicate a TX90p value higher than the reference period value and blue points (negative ATX90p) indicate a TX90p value lower than the reference period value.
The dotted line shows the linear trend of the series (+1,2 %/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.
