Abstract
Detailed comparisons between the Cray output and the Flosolver output for 1-day' forecast using NCMRWF forecast model have been made. The calculations have been made both13; in single precision and double precision for a critical assessment of build up of rowld off error. The calculations show that there are no meteorologically significant differences between the outputs, the remaining difference may be ascribed to the differences in input, machine dependent features, library definition etc. and for practical purposes, single precision calculation is adequate13;
