Advanced Meteorology Tools

Atmospheric soundings, RTMA analysis, and GLM lightning detection. Professional-grade tools for weather enthusiasts, meteorologists, and storm chasers.

Pro-Grade Data on Your iPhone

WeatherAI Pro brings tools that were once limited to desktop workstations to your iPhone. Analyze atmospheric profiles, view high-resolution observational grids, and follow lightning as the GLM feed publishes it, all from the same app you use for daily forecasts.

Atmospheric Soundings

Visualize the vertical structure of the atmosphere with Skew-T/Log-P diagrams. Essential for understanding severe weather potential, inversion layers, and precipitation type.

Skew-T Diagrams

Interactive Skew-T/Log-P charts showing temperature, dewpoint, and wind profiles through the atmosphere. Identify CAPE, CIN, and key atmospheric layers.

Layer Visualization

See temperature inversions, freezing levels, wind shear, and moisture profiles. Understand the atmosphere's vertical structure at a glance.

Hodograph Analysis

Examine changes in wind speed and direction with height, alongside Bunkers storm-motion estimates.

3D Hodograph

Explore the wind profile in 3D. Rotate and zoom the hodograph, compare altitude ranges from 0-3 to 0-12 km, and inspect the storm-relative helicity ribbon.

RTMA Analysis

Real-Time Mesoscale Analysis is NOAA's high-resolution estimate of recent conditions: 2.5km grids, updated hourly, built by combining surface observations with a short-range model background.

High-Resolution Grids

2.5km resolution analysis of temperature, wind, humidity, and pressure. See the fine-scale details that coarser models miss.

Observation-Driven Analysis

RTMA blends real observations with a model background to estimate current conditions rather than forecast future ones. Like any analysis it carries uncertainty, and it is generally most reliable close to observing stations.

GLM Lightning Detection

GOES Geostationary Lightning Mapper provides continuous, near-real-time lightning detection across the Western Hemisphere. Track thunderstorm development and intensity.

Near-Real-Time Total Lightning

GLM flash products plotted on the map, covering in-cloud and cloud-to-ground activity alike. Positions are derived optical centroids seen from orbit at cloud top, so they indicate where lightning activity is happening rather than confirming individual ground strikes.

Flash Density

Visualize lightning flash density to identify the most intense thunderstorms. Higher density areas indicate stronger convection.

Frequently Asked Questions

What is RTMA in weather forecasting?

RTMA (Real-Time Mesoscale Analysis) is a high-resolution analysis produced by NOAA. It combines surface observations with a short-range model background to produce gridded fields of temperature, wind, humidity, and pressure at 2.5km resolution, updated hourly. It estimates recent conditions rather than forecasting future ones, though as an analysis it carries uncertainty and is generally most reliable near observing stations.

What are atmospheric soundings?

Atmospheric soundings are vertical profiles of temperature, moisture, and wind through the atmosphere. They are visualized on Skew-T/Log-P diagrams and are essential for understanding atmospheric stability, severe weather potential, and precipitation types.

How often does GLM lightning data update?

The GOES Geostationary Lightning Mapper (GLM) is an optical sensor that detects total lightning, meaning both in-cloud and cloud-to-ground activity, from geostationary orbit. WeatherAI displays near-real-time GLM flash and density products to track thunderstorm activity as it develops. Plotted positions are derived flash centroids from optical emission at cloud top, not confirmed ground-strike locations.
