A bow echo is a type of mesoscale convective phenomenon that often induces extreme weather and appears with strong reflectivity on radar images. 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.
