PROBLEM TO BE SOLVED: To provide a device for meteorological image analysis capable of accurately detecting the occurrence of meteorologically abnormal conditions, such as tornadoes and gusts, using image data of a weather satellite, and to provide a method therefor and a program. SOLUTION: The device 10 for meteorological image analysis to analyse weather image data by a weather satellite has a processing part 17 that puts acquired weather image data on terrain data, sets a plurality of brightness values, deletes the weather image data of which the brightness is lower than the set value and performs scanning, thereby expressing the presence or the absence of an abnormal weather conditions as a change in the brightness by using the difference in the brightness values.
