Storm Track Map

Track of storm center from the Naval Research Lab.

Lightning Histogram Plot

Three plots are created. The first is of wind speed, pressure, and a histogram of the number of lightning strokes per hour for lightning within 1000 km of the storm center. The second is the same, but only for lightning within 100 km of the storm center. The third plot is a spectrogram showing the number of lightning strokes per three hours binned by the radial distance from the storm center.

Lightning Density Plot

Plots of daily lightning density relative to center of the storm. Daily plots are combined into an animated GIF.

TMI 85 GHz PCT Satellite Overlay

Satellite images from the Naval Research Lab are overlaid with lightning strokes (shown as black circles) +/- 15 minutes of satellite image time. There may be no figures available to view if no satellite images are available.

SSMIS 91 GHz PCT Satellite Overlay

Satellite images from the Naval Research Lab are overlaid with lightning strokes (shown as black circles) +/- 15 minutes of satellite image time. There may be no figures available to view if no satellite images are available.

    Data Access

    This website includes visualizations of WWLLN lightning data, but does not include stroke level data. For stroke level data, please contact Bob Holzworth at bobholz@u.washington.edu.

    Near Real-Time Data

    Note that WWLLN data used for archiving is processed separately from almost real-time WWLLN data. This may cause differences in visualizations as they appear in almost real-time compared with archived versions.
