Forecasters frequently examine point soundings from models to assess the likelihood of deep convection (thunderstorms)…

Soundings from the Operational Eta model often reveal unrealistic structures that can be linked to other things going on in the model

[Image of plotted soundings shows significant differences between observed and modeled data]

NSSL scientists have collaborated with SPC forecasters to compare observed soundings and computer model forecast soundings and found systematic differences.
