The trough will become neutral (North-South) and then negatively tilted as the energy carried by the cold air races east through the atmospheric circulation and distorts its shape. [8] The positive tilt is thus the building phase of the trough and the negative tilt is the dissipation of its energy.
The maximum counter-clockwise spin (positive vorticity in the Northern Hemisphere) is at the trough base. Shear vorticity is caused by the difference in wind speed between air moving through the trough base (typically a jet or jet finger) and slower moving air on either poleward and equatorward side of the faster flow.
An example of positive PNA (left) and negative PNA (right), based on anomalies in the geopotential height of the 500 hPa pressure level. The Pacific–North American teleconnection pattern (PNA) is a large-scale weather pattern with two modes, denoted positive and negative, and which relates the atmospheric circulation pattern over the North Pacific Ocean with the one over the North American ...
Shortwave troughs are a cause of lift, or forcing, which is required for the development of thunderstorms and convection.Convection is very prevalent around shortwave troughs because not only do they provide forcing, but they are also associated with systems that provide other ingredients for the formation of thunderstorms, such as instability, wind shear, and helicity.
