Which of the following processes occurs during baroclinic instability?
A)reduction of wave cyclones
B)no air motion
C)weak wind speed shear from the surface up to at least the 500 hPa level
D)temperature advection

Question

Quizplus · Accepted Answer

Baroclinic instability is the process by which energy is transferred from the horizontal temperature gradients to the atmosphere, leading to the development of mid-latitude cyclones. This process involves the advection of warm and cold air masses, causing a horizontal temperature gradient. As the temperature gradient increases, disturbances or waves are generated in the atmosphere that grow and become unstable. Therefore, the correct process that occurs during baroclinic instability is temperature advection (D). The other options are not accurate in describing baroclinic instability.
