Frontolytical processes are more com-mon in the atmosphere than are frontogenetical processes.
This comes about because there is no known property of the air which is conservative with respect to all the physical or dynamical pro-cesses of the atmosphere. Frontolytical processes are most effective in the lower layers of the atmosphere since surface heating and turbulent mixing are the most intense of the nonconservative influences on temperature. Perpendicular deformation field. Nonperpendicular deformation field. For frontolysis to occur, only one of the two conditions stated above need be met.
