Current Problems in Medium Range Forecasting at ECMWF Data Assimilation Scheme

  • Conference paper
Problems and Prospects in Long and Medium Range Weather Forecasting

Part of the book series: Topics in Atmospheric and Oceanographic Sciences ((TATM))

Abstract

A number of examples show that the analysis, made with the ECMWF data assimilation scheme, and/or the subsequent forecast with the ECMWF forecast model are sensitive to many parameters in the assimilation scheme. Because several of those parameters are not very well known (both qualitatively and quantitatively) this sensitivity poses a severe problem to medium range weather forecasting at ECMWF. The sensitivity is particularly related to insufficiency of accurate observational data.
