- Аннотация: The development of satellite technologies and its application in meteorological researches led to an increasing of the information received from satellites last years. In recent years the RGB-compositions, visualizing data in different wavelengths, are actively being created. These compositions are useful in the manual analysis of synoptic situations, but their large number complicates and slows down the manual processing of the visual information. To overcome this problem we made EVSI software. With this software a user can choose a type of satellite information for each color channel. The creation of the efficient software, which would provide more easy and convenient way of the analysis of obtained images, was the purpose of our work. The results of an atmospheric scanning by satellite METEOSAT-10 were the input data for our program. With EVSI the RGB-composition was created. It is usable for the primary analysis of a synoptic situation over a required region without any other information. This composition is the combination of 10.8 and 6.2 micron channels and the difference of 6.2 and 7.3 micron channels. The cloud structure looks like white area, so it is easy to differentiate and analyze it. The towering clouds with the precipitation regions and the potential severe weather activity are colored in bright blue on a white background. Additionally, the RGB-composition helps to find information about the properties of air masses. All of it contributes to a fast detection, analyzing and forecasting of the weather in the required region.
