New Severe Weather Tracking Layer

by Rory Groves        April 30, 2010  |  9:33 am  |  Category: Latest News | Tips & Tricks

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
