During the two Special Observing Periods of the First GARP Global Experiment (FGGE) a data assimilation experiment was conducted at the UK Meteorological Office. Throughout the period of the experiment observational data were assimilated dynamically into a numerical forecast model at the four main synoptic hours of each day. In the first part of the paper, the method of data assimilation is briefly described. Following that, a description is given of the zonally averaged atmospheric circulation, as diagnosed from our analyses. The results of this study are in generally good agreement with those found by previous workers.
