Opening report
1. Research background and significance
With the development of the information age, people's demand for data is increasing. Data visualization, as a way to transform abstract data into intuitive graphics, can help people better understand and analyze data and make more accurate decisions. As an important information service, weather forecast has an important impact on people's lives and work. Therefore, visual analysis of weather forecast data can allow people to understand weather conditions more intuitively, improve their ability to predict weather, and provide people with better life services.
As a city located in a mountainous area, Guiyang, Guizhou has variable weather conditions, and the climate difference between mountainous and plain areas is large. For residents and tourists, accurate weather forecast data is particularly important. However, Guiyang currently does not have a system that comprehensively and intuitively displays weather forecast data, and lacks a platform that can centrally display various weather data. Therefore, the design and implementation of a Python Guizhou Guiyang weather forecast data visualization large-screen full-screen system is of great significance for improving the quality of life and travel safety of Guiyang citizens and tourists.
2. Research status at home and abroad
At present, there have been many studies on weather data visualization at home and abroad. Domestic research mainly focuses on Web-based weather data visualization methods, such as weather data visualization system based on D3.js, meteorological data visualization system based on ECharts, etc. These systems use visualization technology to transform weather data into intuitive charts and maps, allowing users to more easily understand and analyze weather conditions. However, most of these systems simply display weather data and lack in-depth analysis and mining of the data.
Foreign research mainly focuses on weather data mining and prediction, such as weather data prediction models based on machine learning, weather data analysis models based on deep learning, etc. By learning and analyzing weather data, these models can predict future weather conditions and provide more accurate weather forecasts. However, these models require a large amount of data and computing resources, are suitable for large-scale meteorological data analysis, and are not suitable for weather data visualization of a single city.
To sum up, current domestic and foreign research on weather data visualization mainly focuses on Web-based visualization systems and weather data mining models. In Guiyang City, there is not yet a system that comprehensively and intuitively displays weather forecast data. Therefore, this research will design and implement a python Guizhou Guiyang weather forecast data visualization large-screen full-screen system based on the Django framework to meet users' needs for weather data.
