Weather Comes from Boundaries

🌬️ Air masses resemble their birthplace. Born over the sea, they’re damp; from the north, they’re cold. Choose two, and Korea’s four air masses appear — like Siberia in winter and the North Pacific in midsummer. ⚡ When cold and warm air meet, weather forms at that «boundary». Stand in three spots around a front: ahead, right under it, and behind it. The same front brings clear skies ahead, a downpour underneath, and cool clearing behind. 🌀 Finally, follow a day as a low-pressure system passes: widespread rain → a brief warm, clear spell → showers → a chilly clearing. The order is set. But why does the northern village stay cloudy all day? Stand in both villages side by side to find out. This app was coded too · Shall we remix it and add a typhoon?
About this app
Weather Is Born at the Border is an interactive middle school science learning app about air masses, fronts, and low-pressure systems. Learners select where an air mass forms to see how latitude and land or sea affect temperature and humidity, then explore weather conditions at different positions around a front. A final simulation follows a west-to-east low-pressure system through two towns, showing how rain, temperature, and cloud cover change over time.
Use cases
- Middle school students studying weather systems
- Teachers introducing air masses and fronts
- Learners reviewing Korean regional weather concepts
- Classroom demonstrations of low-pressure weather sequences
Features
- Interactive air-mass builder using land or sea and north or south choices
- Profiles of Siberian, Okhotsk, North Pacific, and Yangtze air masses
- Front simulation with cold or warm air and three observation positions
- Visual comparisons of cloud width, rainfall, and temperature
- West-to-east low-pressure simulation across southern and northern towns
- Mission-based progression with reset, next, and completion feedback
