Radar image of a bow echo crossing Kansas City at 2:14 AM on 2 May 2008 (NWS Kansas City) A bow echo is the characteristic radar return from a mesoscale convective system that is shaped like an archer's bow. These systems can produce severe straight-line winds and occasionally tornadoes, causing major damage.
Radar schematic of a LEWP. This shape is a single wave along the pattern, for real LEWPs this shape is tessellated repeatedly in a linear fashion. A line echo wave pattern (LEWP) is a weather radar formation in which a single line of thunderstorms presenting multiple bow echoes forms south (or equatorward) of a mesoscale low-pressure area with a rotating "head".

Multi-bow – Multiple bow derechos are embedded in a large squall line typically around 400 km (250 miles) long. One example of a multi-bow serial derecho is a derecho that occurred during the 1993 Storm of the Century in Florida. [15] Because of embedded supercells, tornadoes can spin out of these types of derechos. This is a much more common ...

The rear-inflow jet is a component of bow echoes in a mesoscale convective system that aids in creating a stronger cold pool and downdraft. The jet forms as a response to a convective circulation having upshear tilt and horizontal pressure gradients. The cold pool that comes from the outflow of a storm forms an area of high pressure at the surface.
