Baadal: I Built an App That Teaches You to Read the Sky Again

说明与用途

Baadal 是一个网页应用，用户拍摄天空照片后可获得三小时降雨概率，并学习识别云层以进行天气预测。

问题

People rely on generic weather apps that give a 40% chance of rain, but they do not use the most immediate source of weather information – the sky itself.

结果

Baadal provides a 30‑second interaction that compares a rain probability derived from the sky with one derived from weather data alone, demonstrating the added value of visual cloud analysis. In three test photos, the app correctly identified cloud types and produced low rain probabilities that matched the actual weather outcomes.

工作流

• Look up and take a photo or upload one
• Gemma 4 analyzes the photo and outputs cloud type, coverage, towering, confidence
• TabPFN combines the cloud analysis with live humidity, pressure, 3‑hour pressure trend to predict rain probability
• Gemma presents a two‑sentence explanation and a tip for future sky reading
• User logs whether it rained or stayed dry after 3 hours to keep an honest score

证据

Gemma 4 reads the clouds. It names the cloud type (cumulus, stratus, cirrus and the rest of the 10 WMO genera), estimates how much of the sky is covered, and checks for towering growth.

来源

TabPFN does the forecasting. It combines what you saw with live humidity, pressure and the 3-hour pressure trend, and returns a rain probability.

The result screen shows two bars side by side: "With your eyes" (your photo + weather data) and "Weather data only".

Gemma named a different cloud type for each sky, and the low numbers fit a dry October evening and night.
