Discussions (Mesoscale / Tropical)

---

Configurations: sources.dicussion_settings

Sourced from weatherwise.app, these discussions cover topics such as mesoscale and tropical storms. Currently, there are no configurable settings or alerting capabilities for these discussions. In future updates, we plan to enable integration with the alerts widget so that relevant discussions can trigger notifications.

Mesoscale Discussions

By default, AtmosphericX will fetch all active mesoscale discussions every 2 minutes from the WeatherWise API. This also supports fallback subdomains including data, data1, and data2 to ensure reliability in fetching the latest discussions. If you wish to modify the refresh interval, you can adjust the cache_time for mesoscale discussions in dicussion_settings.mesoscale_discussions.cache_time.

Data can be requested at /data/discussions and is returned in the following GeoJSON format:

{
    "type": "FeatureCollection",
    "geometry": {
        "type": "Polygon",
        "coordinates": [ ... ]
    },
    "properties": {
        "mesoscale_id": "1234",
        "expires": "2026-03-23T14:00:00Z",
        "issued": "2026-03-23T12:00:00Z",
        "description": "...",
        "locations": "...",
        "outlook": "...",
        "population": 500000,
        "homes": 200000,
        "parameters": {
            tornado_probability: 10,
            wind_probability: 20,
            hail_probability: 15,
        }
    }   
}

Tropical Discussions

Tropical discussions are also sourced from WeatherWise and are refreshed every 20 minutes by default. Similar to mesoscale discussions, you can modify the refresh interval for tropical discussions in dicussion_settings.tropical_storms.cache_time if you want to receive updates more or less frequently.

Data can be requested at /data/tropical_storms and is returned in the following GeoJSON format:

{
    "type": "Feature",
    "properties": {
        "name": "Tropical Storm Name Here"
        "discussion": "...",
        classification: "Tropical Storm",
        "pressure": 1000,
        "max_sustained_winds": 50,
        "last_updated": "2026-03-23T12:00:00Z"
    }
}
