Using the Python language, the decoding and visualization of the new generation Doppler weather radar storm data is realized. Through the establishment of the storm automatic matching method and in use of Python geographic information visualization and time series visualization technology, the animation display effect of storm tracking is achieved. By using Python data analysis and chart visualization technology, the multidimensional information of the storm can be displayed in the chart, and the trend of the storm can be intuitively displayed. The work in this paper provides a more general method to get the storm information quickly, which brings convenience to weather forecasters to use the radar data. Meanwhile, the enhanced visualization of storm information improves the reuse of data and supports the researches in the field of expertise.
