The results of three quasi-objective techniques for enhancing the accuracy of 24-hour cloud cover forecasts in sparse data areas, using satellite data and numerically-produced analyses and prognoses, are presented. All three of the techniques involve the modification of the analyzed 500-mb relative vorticity, as based on the satellite-observed cloud patterns and the associated changes to the prognostic fields of 500-mb relative vorticity. The study was conducted over a large area of the North Pacific Ocean for the period 9 March to 13 April 1972. Author Modified Abstract
