城市天气数据可视化项目（含源码，数据源，运行结果，文档！）
资源内容介绍
本项目通过网络爬虫获取了温州市2014年至2024年的天气数据，包括日期、最高气温、最低气温、天气情况和风力情况。首先，爬取并解析网页数据，将其存储为Excel文件。接着，对数据进行清洗和处理，去除重复数据和缺失值。数据分析部分，绘制了多个图表，包括近十年气温变化折线图、2023年最高和最低气温折线图、2023年天气情况柱状图、天气类型环形图和风力玫瑰图。最后，使用线性回归模型对次日最高气温进行预测，生成了当日与次日最高气温的散点图和回归直线图。通过这些分析和图表展示，揭示了温州市近十年的气温变化趋势及天气特征，并评估了模型的拟合效果。
