Fig. 2: Linear regression model’s forecast.
From: Seasonal prediction of Indian summer monsoon extreme rainfall frequency
a Independent hindcast of Normalized seasonal ERE frequency anomaly and (b) Normalized ERA anomaly forecast over CI between 2003 and 2022 generated by the linear regression model at 1-month lead (red) and 6-month lead (blue). The observed normalized seasonal ERE frequency and ERA anomalies generated from 1° x 1° grid boxes are presented by the black curve. c, d Correlation between May D20 and seasonal ERE frequency anomalies over the period 1960–2002 and 1960–2003, respectively. e Difference between the correlation maps shown in (c, d).
