AI Technical Summary

Technical Problem

In the existing technology, there is a lack of a unified and objective judgment method for evaluating snowfall and freezing, which makes it impossible to achieve seamless integration between real-time evaluation and predictive assessment of snowfall and freezing days. Furthermore, the disaster intensity assessment of snowfall and freezing rain lacks comprehensiveness, resulting in predictive assessments in meteorological decision-making services being unable to be compared and referenced with real-time assessments.

Method used

This paper provides a method for real-time evaluation and predictive assessment of snowfall and freezing weather. By converting snowfall and freezing rain observation data, a threshold for judging snowfall and freezing days is determined. The threshold method is then used to evaluate the intensity, duration, and intensity of snowfall and freezing days. Finally, a comprehensive assessment is conducted in conjunction with meteorological forecast products.

Benefits of technology

It achieves a unified approach to real-time and predictive assessment of snowfall and freezing events, providing more accurate disaster intensity level analysis and offering more precise services for emergency decision-making by government, transportation, education, agriculture, heating, and power supply departments.

Abstract

The application discloses a snow and freezing weather instant evaluation and predictive evaluation method, which respectively carries out incremental change processing on snow and wire icing observation values, is consistent with the physical meaning represented by the snow and freezing rain prediction in weather prediction services, solves the problem of the mismatch between observation data and prediction quantity expression forms, and realizes seamless connection of instant evaluation and predictive evaluation of the same method on snow and freezing days and processes; the method adopts a comprehensive quantitative index to determine the intensity of snow and freezing days and processes in which snow and freezing rain independently or superimposedly appear, and solves the problem of different methods required for analysis when snow and freezing rain appear simultaneously. Through the application, according to the snow and freezing rain prediction products of meteorological departments, and with reference to instant evaluation of historical snow and freezing days and processes, predictive evaluation of future snow and freezing days and processes can be realized, and more accurate services can be provided for emergency decision-making and industry scheduling of government, transportation and power supply departments.
