When an upper-level low lies directly above a surface low, the surface low will probably weaken. This is because the upper-level low induces sinking air that suppresses the development and intensification of the surface low. As the surface low weakens, its pressure may increase or stay the same, but it is unlikely to decrease significantly. Thunderstorms may or may not develop depending on the strength and moisture content of the environment around the surface low, and a wave cyclone is a specific type of cyclone that may or may not form in this situation, depending on other factors such as the orientation of the pressure gradients and the timing of the upper-level forcing.
