Pel cas de Catalunya s’han elaborat a partir de 28 s\u00e8ries di\u00e0ries de temperatura m\u00e0xima i temperatura m\u00ednima i 73 de precipitaci\u00f3 des de 1950, que pr\u00e8viament han estat sotmeses a un control de qualitat i homogene\u00eftat.<\/p>\n\n\n\n

\u00cdndexs de temperatura de l’aire. 1950-2024<\/h2>\n\n\n\n

S’han obtingut 23 \u00edndexs de temperatura de l’aire per a un conjunt de 28 s\u00e8ries di\u00e0ries. L\u2019\u00e0rea dels triangles \u00e9s proporcional al valor de la tend\u00e8ncia decennal. El triangle s\u00f2lid indica que la tend\u00e8ncia \u00e9s estad\u00edsticament significativa, segons el test de Mann-Kendall (p<0,05).<\/p>\n\n\n\n
