BWER Acronym for Bounded Weak Echo Region. Refers to radar echo signatures with low reflectivity in the center, surrounded by higher reflectivity.

BWER
Abbreviation for Bounded Weak Echo Region; a radar signature within a thunderstorm characterized by a local minimum in radar reflectivity at low levels which extends upward into, and is surrounded by, higher reflectivities aloft.

BWER: An acronym for Bounded Weak Echo Region. See Bounded Weak Echo Region.

BWER - Bounded Weak Echo Region. Also known as a vault. Radar signature characterized by an area of weak radar reflectivity at low levels which extends upward into, and is surrounded by, higher reflectivities aloft (Figure 2).

BWER - Bounded Weak Echo Region. Radar feature showing a region on the inflow side of a thunderstorm, especially a supercell, where the RFD and FFD precipitation surrounds the area forming an "opening". Common on the southeast side of such storms.

A bounded WER (BWER) develops where the intense updraft is surrounded by mid-level overhang.

Vault Same as BWER.
Veering Wind Wind which changes in a clockwise direction with time at a given location (e.g., from southerly to westerly), or which change direction in a clockwise sense with height (e.g.

When the area of low reflectivity extends upward into, and is surrounded by, the higher reflectivity aloft, it becomes a BWER. West African Disturbance LineA line of convection about 300 miles long, similar to a squall line.

Bounded weak echo region (or BWER)
This is a region of low reflectivity bounded above by an area of higher reflectivity. This is evidence of a strong updraft.
Inflow notch ...

Radar characteristics often (but not always) include a hook or pendant, bounded weak echo region (BWER), V-notch, mesocyclone, and sometimes a TVS.

The WER is a sign of a strong updraft onthe inflow side of a storm, within which precipitation is held aloft. When the area of low reflectivity extends upward into, and is surrounded by, the higher reflectivity aloft, it becomes a BWER.

middle and upper levels above an area of weak reflectivity at low levels. (The latter area is known as a weak-echo region, or WER.) The overhang is found on the inflow side of a thunderstorm (normally the south or southeast side). See Fig. 2, BWER.

the 2 end points are operator selected anywhere within 124 nm of the radar that are less than 124 nm apart. It is used to:
1) Examine storm structure features such as overhang, tilt, Weak Echo Regions (WER), and Bounded Weak Echo Regions (BWER);
2) ...
