Issues related to NAM Precipitation AnalysesIssues related to NAM Precipitation Analyses
• What are the most appropriate metrics for comparing/ validating precipitation estimates from models and remotely sensed platforms with NERN and other station-based datasets?
– Merged datasets
– Area integrations (NAME verif. zones, gridded anal., watershed avgs., etc.)
– Climatology vs. case studies
– Linking precipitation character w/ forcing mechanisms
• Exactly how does precipitation propagate off of the SMO?– Modeling and NERN evidence that precipitation may move away from SMO to
west AND east
• Extending analyses to encompass larger N. American region
Covariance between NAMS and US?:Covariance between NAMS and US?:
• SW – Cont. US correlations are v. weak and explain v. little of overall σ2
• However, statistically significant evidence for weak anit-correl at lag 0 with transition to pos. correls at (US) lag 4
