逐时度假气候指数网格预报产品数据

提供的未来3天逐3、6、12小时度假气候指数数据，覆盖安吉的72个网格格点，每天两次滚动发布。这些数据基于精细化的网格预报技术，能够为用户提供基于位置的高分辨率度假气候信息。用户调用后可根据实际位置匹配最近网格等方法直接使用。这些数据可以直接为旅游业提供实时的天气条件评估，帮助旅游规划者和游客做出更合理的行程安排，提升旅游体验。自动提取安吉范围智能网格逐3、6、12小时客观预报产品，建立气象要素与度假气候指数的统计关系，结合标准化度假气候指数算法和规则本地化后自动生成逐3、6、12小时度假气候指数智能网格客观预报产品。标准化度假气候（HCI）指数算法由热舒适因子、审美因子、物理因子三个因子按照不同权重构成，综合了气温、湿度、降水、云量、风速等气象要素。其计算公式为：HCI=4T+2A+（3R+V）;T=Ta-0.55（1-Rh）（Ta-14.4）。式中，T为有效温度，表征热舒适因子，即人体对温度高低的感觉，由最高气温Ta和相对湿度Rh计算；A为云覆盖率，表征审美因子；R为降水量，V为风速，两者综合用来表征物理因子。根据上式计算HCI，建立其对应的旅游气候分级标准。

This dataset provides vacation climate index data at 3-, 6-, and 12-hour intervals for the next three days, covering 72 grid points in Anji, with two rolling updates per day. Based on refined grid forecasting technology, this dataset can provide users with location-based high-resolution vacation climate information. Users can directly access and use this data by matching the nearest grid point based on their actual location upon retrieval. This data can directly provide real-time weather condition assessments for the tourism industry, helping tourism planners and tourists make more reasonable travel arrangements and enhance their travel experience. By automatically extracting 3-, 6-, and 12-hour interval objective forecast products for intelligent grids across the Anji region, establishing the statistical correlation between meteorological elements and vacation climate indices, and combining the standardized Vacation Climate Index (HCI) algorithm with locally adapted rules, the 3-, 6-, and 12-hour interval intelligent grid objective forecast products of vacation climate indices are automatically generated. The standardized HCI algorithm is composed of three factors—thermal comfort factor, aesthetic factor, and physical factor—with different weight coefficients, integrating meteorological elements including air temperature, humidity, precipitation, cloud cover, and wind speed. Its calculation formula is as follows: HCI = 4T + 2A + (3R + V); T = Ta - 0.55(1 - Rh)(Ta - 14.4). Herein, T represents the effective temperature, which stands for the thermal comfort factor, i.e., human perception of temperature intensity, and is calculated using the maximum air temperature Ta and relative humidity Rh; A is the cloud cover proportion, representing the aesthetic factor; R denotes precipitation, and V denotes wind speed, which together represent the physical factor. The HCI is calculated based on the aforementioned formula, and the corresponding tourism climate classification standards are established.
