The direction to which the polygon or line is moving to, e.g. movement to the east would be encoded as 90 degrees. This direction does not necessarily correspond to the movement related to individual convective element(s) or cells within the polygon.
Speed of polygon or line movement. Unit of measure shall be given in knots ("[kn_i]").
A codelist of maximum convective cloud top heights
Estimate of the amount of convection that "fills" the polygon. See codelist for category amounts in percentages.
The 'solidity' of the convective line. See code list for categorical amounts in percentages.
Estimated forecaster confidence. See code list for qualitative terms.
Probability of Thunderstorms in percentages (%).
When the convective feature is best described as closed shape.
