What it does

  • Read the vertical profile

    View temperature, dewpoint, parcel traces, wind barbs, and key levels on a familiar Skew-T log-P display.

  • Connect numbers to storm potential

    Compare CAPE, CIN, LCL, LFC, EL, lifted index, DCAPE, PWAT, shear, SRH, storm motion, and composite parameters.

  • Inspect the wind profile

    Use the hodograph and Bunkers storm motions to understand shear, turning, and the storm modes an environment may favor.

  • Work with the data you need

    Load the latest available station profile or open Wyoming text, WMO TEMP, and BUFR files for case studies and research.

  • Soundings profile and hodograph display
    Read the thermodynamic profile and wind environment together.
  • Soundings upper-air analysis artwork
    Move from the overall profile to the parameters that answer your forecast question.

A sounding is most useful when it helps you answer a specific question: Is the cap likely to hold? How much buoyancy is available? Is the wind profile supportive of organized storms? Where are the important cloud and parcel levels?

Soundings keeps the profile, hodograph, parcel comparison, and derived parameters close together so you can move from the shape of the atmosphere to a practical interpretation. Operational thresholds give the numbers context instead of leaving you with an unexplained table.

Use current station observations for forecast preparation, step through recent launches to watch the environment evolve, or open your own files for research and case review. The same focused experience works across iPhone, iPad, and Mac.

Frequently asked questions

What does a sounding tell me?

A sounding shows how temperature, moisture, and wind change with height. Those changes help you assess instability, capping, cloud levels, shear, storm motion, and potential storm mode.

Which devices does Soundings support?

Soundings is available for iPhone, iPad, and Apple-silicon Mac. The current release requires iOS or iPadOS 17 or later on mobile devices.

Where does the station data come from?

The app lets you browse reporting upper-air stations and load the latest available observed profile for a selected site.

Which file formats can I open?

You can open Wyoming text, WMO TEMP code, and BUFR sounding files for archived cases, research launches, and other local analysis.

Which severe-weather parameters are included?

The app includes CAPE, CIN, LCL, LFC, EL, lifted index, DCAPE, PWAT, effective shear, storm-relative helicity, Bunkers storm motion, and several composite parameters when the required data are available.

Is Soundings a subscription?

No. Soundings is a $1.99 one-time App Store purchase.
