  We use the suite of simulations presented in Poole et al (2006) to examine
global X-ray and Sunyaev-Zel'dovich (SZ) observables for systems of merging
relaxed X-ray clusters. In all of the scaling relations generated from the
properties we have studied, we observe a generic evolution (in good qualitative
agreement with previous authors): a rapid transient roughly along the mass
scaling relations, a subsequent slow drift across the scatter until
virialization, followed by a slow evolution along and up the mass scaling
relations as cooling recovers in the cluster cores. However, this drift is not
sufficient to account for the observed scatter in the scaling relations. We
also study the effects of mergers on several theoretical temperature measures
of the intracluster medium: emission weighted measures (T_ew), the
spectroscopic-like measure proposed by Mazzotta et al (2004; T_sl) and plasma
model fits to the integrated spectrum of the system (T_spec). We find that T_sl
tracks T_spec for the entire duration of our mergers, illustrating that it
remains a good tool for observational comparison even for highly disturbed
systems. Furthermore, the transient temperature increases produced during first
and second pericentric passage are 15-40% larger for T_ew than for T_sl or
T_spec. This suggests that the effects of transient temperature increases on
sigma_8 and Omega_M derived by Randall et al (2002) are over estimated. Lastly,
we examine the X-ray SZ proxy proposed by Kravtsov et al (2006) and find that
the tight mass scaling relation they predict remains secure through the entire
duration of a merger event, independent of projection effects.
