10. Weather Terms (Korean)

11. Best Practices

Query Strategy

1. For current weather: Use weather-forecast page
2. For hourly forecast: Use hourly-weather-forecast with day parameter
3. For multi-day forecast: Use daily-weather-forecast
4. For sunrise/sunset: Use weather-today page
5. For air quality: Use air-quality-index page

Information Prioritization

When user asks for weather without specifying details:

1. Temperature (high/low or current)
2. Weather condition
3. Precipitation probability
4. Wind information
5. UV index and Air quality (if relevant)
6. Sunrise/sunset (if relevant)

Time Reference

• Always clarify the date being referenced (today, tomorrow, specific date)
• Use 24-hour format for time in Korean context
• Note the forecast issuance time if available
