| Abstract: | In this paper the bromine family and radiative effects are considered
in an updated box model under the framework of ozone--temperature feedback,
in order to further analyze the possible behavior of atmospheric ozone in the
lower mid-latitude stratosphere. Results show that this updated photochemical
system can present several different solutions, within a certain domain of parameters,
with fixed-point and periodic states appearing in turn. The temperature feedback
effect introduced in this box model has not changed the topology of the ozone system.
This result presents nonlinear characteristics of the ozone system, and possible
trends in the stratospheric atmosphere between complex chemistry and radiation processes. |
