For example, increases in net energy input to the tropical atmosphere tend to narrow the ITCZ whereas increases in energy transport by
transient eddies tend to widen the ITCZ.
For example, equatorward - moving weather systems — known as «
transient eddies» — fulfill much of the poleward energy export required to balance the net energy input, with the energy transport associated with vertical motion times gross moist stability less important than in the ITCZ.
Consequently, the vertical velocity in the descent region is a function not only of the net energy input to the atmosphere and the gross moist stability, but also of the energy transport by
transient eddies and mean advection.
Analogous arguments can be made to understand the influences of
transient eddies, gross moist stability and mean advection on changes in the ITCZ width.

Transient -
eddy changes are also important in the midlatitudes (beyond 30 degrees latitude).
The total implied dynamic change, which results from stationary -
eddy circulation changes and
transient -
eddy moisture flux changes, is negative at most latitudes.
Combining these equations for the mass and energy balances of the Hadley cell, we can write the ratio of the ITCZ area to the area of the descent region in terms of the gross moist stabilities in each region, the respective net energy inputs, and the mean advection and

eddy terms in the energy budget:
