Query: Generation of quasi-periodic waves and flows in the solar atmosphere by
  oscillatory reconnection   We investigate the long-term evolution of an initially buoyant magnetic flux
tube emerging into a gravitationally-stratified coronal hole environment and
report on the resulting oscillations and outflows. We perform 2.5D nonlinear
numerical simulations, generalizing the models of McLaughlin et al. (2009) and
Murray et al. (2009). We find that the physical mechanism of oscillatory
reconnection naturally generates quasi-periodic vertical outflows, with a
transverse/swaying aspect. The vertical outflows consist of both a periodic
aspect and evidence of a positively-directed flow. The speed of the vertical
outflow (20-60 km/s) is comparable to those reported in the observational
literature. We also perform a parametric study varying the magnetic strength of
the buoyant flux tube and find a range of associated periodicities: 1.75-3.5
min. Thus, the mechanism of oscillatory reconnection may provide a physical
explanation to some of the high-speed, quasi-periodic, transverse outflows/jets
recently reported by a multitude of authors and instruments.
