Correlation skills of hindcasts: (a) seasonal rainfall total; (b) rainfall frequency; (c) mean daily intensity; (d) monsoon onset date. Circle diameter is proportional to magnitude of the correlation. Negative correlations omitted. Onset date is defined as first wet day of the first 5-day sequence receiving at least 40 mm that is not followed by a dry 10-day sequence receiving less than 5 mm within the following 30 days from the onset date, computed from 1 August.
