STEP BY STEP DEEP CONVECTION NOWCASTING
1. Pre-Convective Environment
Refers to the 4-D thermodynamic and wind field present before the convective initiation occurs.
2. Convective Initiation
Refers to the process where an existing cumulus cloud begins rapid vertical growth.
3. Mature Convective Storm
Refers to the presence of convective clouds with tops at or above their local equilibrium level.
