Classification order of daily precipitation from 2001 to 2019 using the quantile technique for the city of Recife—PE with the appropriate classes and probabilities, where Qy (y = 5, 25, 50, 75, and 95%) is the quantile limit used for each classification and y is the precipitation value of the sample.

Classification	Quantile
Dry day	y < Q0.05
Very weak	Q0.05 ≤ y < Q0.25
Weak	Q0.25 ≤ y < Q0.50
Moderate	Q0.50 ≤ y < Q0.75
Strong	Q0.55 ≤ y < Q0.95
Very strong	y ≥ Q0.95
