A new layer based on the Mesocyclone Detection Algorithm (MDA) was released today. Mesocyclones indicate areas of rotation inside a thunderstorm, which can be precursors to Wall Clouds and Tornadoes.
This freely available layer to all registered Weather Defender customers provides the following benefits:
- More accurate and frequent updates concerning rotation inside thunderstorms (precursors to tornadoes)
- Detailed information about the strength, dimension, and movement of each circulation
- Historical and future tracks of the circulation for long-lived mesocyclones
Here's how to add this new layer to your map:
1. Unlock your map by clicking the padlock icon in the upper-right of the Map Layers window
2. On the main toolbar, click Map > Add Layer
3. In the Layer Browser, click the Severe Weather category
4. Find the layer labeled "Meso (MDA)" and click Add To Map
