Damaging Downburst Prediction and Detection Algorithm (DDPDA)

Display

Present Display:

One column in cell table:

SEVPRD - severe prediction
MODPRD - moderate prediction
SEVDET - severe detection
MODDET - moderate detection
HICORE - elevated reflectivity core precursor detected
SEVCNV - strong mid-level convergence precursor detected

Time-height trends of reflectivity, SCIT thresholds, and velocity difference (conv/div)
Icons for predictions and detections

Forecasters, including the SRAD/SWAT Users Group, have recommended that we move toward a more probablistic aproach, much like HDA. Proability of Severe Wind Graph

Other future possibilities include:

Damaging Wind Table:

Downburst probabilities
List of strength of top precursors

Rapid Update for detections
Gridded Convergence Field (bow echoes)

NWS forecasters have suggested removing Moderate Predictions, since they are only interested in storms that produce > 25 m/s gusts.

[It would be nice to also have a maximum predicted gust, much like HDA's hail size estimate]

[We need some way to see the input to the equations without building another table]
