EF Scale

Usually, instruments do not measure the maximum wind speed of a tornado directly. Thus, surveyors use the damage that the wind caused to find the EF rating of a tornado. EF Scale makes the Enhanced Fujita Scale easier to use. You can use it to examine previous tornadoes, to record damage outdoors, or to know more about the scale.

Radar Mobile

Use Radar Mobile to monitor a storm when you are away from your computer. First, use the CONUS mosaic to find storms, and then zoom in to one radar site. If one radar product does not show all the data that you want, use two panels.

Soundings

A sounding helps you examine the atmosphere before storms start. Use it to examine forecast problems. For example:

• Can the cap stop storms?
• How much buoyancy is available?
• Is there sufficient wind shear for organized convection?
• At which heights are the important cloud and parcel levels?

Soundings keeps the sounding, the hodograph, the parcel curves, and the derived parameters together on one screen. Thus, you can start with the shape of the sounding and then make a forecast from it. The app compares each parameter with operational thresholds. These thresholds help you read the numbers.

WeatherWall

The next WeatherWall will bring a native radar workspace to iPhone, iPad, Mac, and Apple TV. Its new rendering engine will support live radar and archive playback, with controls suited to each platform.
