A New Founded Error Contamination Mechanism in Numerical Weather Forecasting Models

A New Founded Error Contamination Mechanism in Numerical Weather Forecasting Models

Traditionally speaking, the error growth rate is considered unpredictable because of the uncertainty of unavoidable errors in data collection. A new kind of errors can be detected in the forecast with a non-uniform continuity index. The results based on a simulation of the T213 ECMWF model support o...

Zusammenfassung:Traditionally speaking, the error growth rate is considered unpredictable because of the uncertainty of unavoidable errors in data collection. A new kind of errors can be detected in the forecast with a non-uniform continuity index. The results based on a simulation of the T213 ECMWF model support our new founded facts that the errors caused by non-uniform continuity between the forecast fields and analysis fields is a new founded error contamination mechanism in numerical weather models.
