Inflow Notch

Inflow Notch - A radar signature characterized by an indentation in the reflectivity pattern on the inflow side of the storm. The indentation often is V-shaped, but this term should not be confused with V-notch.

Inflow notch
An "notch" of weak reflectivity on the inflow side of the cell. This is not a V-Notch.
V Notch ...

This term should not be confused with inflow notch or with enhanced V, although the latter is believed to form by a similar process.

Heavy precipitation supercells have some identifiable radar features, including "broad hooks" and/or large inflow notches on the east and southeast storm flank.

The V-notch often is seen on supercells, and is thought to be a sign of diverging flow around the main storm updraft (and hence a very strong updraft). This term should not be confused with inflow notch or with enhanced V, ...

field, seen as a V-shaped notch in the downwind part of a thunderstorm echo. The V-notch is thought to be a sign of diverging flow around the main storm updraft (and hence a very strong updraft). This term should not be confused with inflow notch.
