+# NavSea Weather Server
+Task: WeatherServer_Pipeline
+Architecture: NavSea V11
+Codex: codex6
+Status: TODO
+
+---
+
+# 1 任务目标
+
+创建 Weather Pipeline。
+
+Pipeline 负责自动执行整个天气数据生产流程：
+
+Downloader
+→ Grid Builder
+→ Vector Tile Generator
+
+输入：
+
+NOAA GFS
+
+输出：
+
+/weather/{time}/{z}/{x}/{y}.pbf
+
+用于 NavSea 客户端加载天气图层。
+

+
+# 2 Pipeline 结构
+
+weather_server/
+
+downloader/
+grid/
+tiles/
+pipeline/
+
+创建文件：
+
+weather_server/pipeline/weather_pipeline.py
+

+
+# 3 Pipeline 执行流程
+
+step1 下载 GRIB
+
+step2 生成 Weather Grid
+
+step3 生成 Vector Tiles
