Line echo wave pattern

line echo wave pattern"(Abbreviated LEWP.) A special configuration in a line of convective storms that indicates the presence of a low pressure area and the possibility of damaging winds and tornadoes.

LINE ECHO WAVE PATTERN (LEWP) A wave-shaped bulge in a line of thunderstorms. It may often be seen as a "S"-shaped radar echo signature and is often associated with severe weather.

Line Echo Wave Pattern (LEWP) A radar echo pattern formed when a segment of a line of thunderstorms surges forward at an accelerated rate. A meso-high pressure area is usually present behind the accelerating thunderstorms.

LEWP - Line Echo Wave Pattern. A bulge in a thunderstorm line producing a wave-shaped "kink" in the line. The potential for strong outflow and damaging straight-line winds increases near the bulge, which often resembles a bow echo.

LEWP - Line Echo Wave Pattern. A feature within a line of storms that resembles a wave with a mesolow at the crest of this feature. Often associated with multiple bowing segments within a larger squall line.

LEWP- Stands for Line Echo Wave Pattern. This is an outward bulge along a squall line that is often created from strong upper level winds intersection that segment of the squall line.

Weather near the center of this bow pattern is dominated by strong and damaging outflow winds. A series of bows along a squall line is called a LINE ECHO WAVE PATTERN or LEWP. May also be called a BOW OUT.

Areas of circulation also can develop at either end of a bow echo, which sometimes can lead to tornado formation - especially in the left (usually northern) end, where the circulation exhibits cyclonic rotation. See also Line Echo Wave Pattern ...

LINE ECHO WAVE PATTERN (LEWP) A bulge in a line of thunderstorms, producing a wave-shaped in the line. It is seen as a scalloped radar echo signature and is often associated with severe weather.
