Based on the observed facts and actual experience as well as the qualitative analysis and diag-noses on the cloud structure characters of satellite images

some judgement factors and fuzzy inference rulesfor classifying cloud were picked-up by using fuzzy inference method with fuzzy/defuzzy treatment on thejudgement factors and optimization adjustment on the membership functions

a quantitative fuzzy inferencemodel for classifying cloud of satellite images was established. The results of 4 kinds of common cloud’sfuzzy inference classification experiments show that the fuzzy inference method is superior to traditionaldiscriminance in the aspect of quantification

objectivity and automatization

which promises to be appliedin the fields of satellite remote sensing data treatment and weather forecast.
