  The properties of low-frequency convective fluctuations and transport are
investigated for the boundary region of magnetized plasmas. We employ a
two-dimensional fluid model for the evolution of the global plasma quantities
in a geometry and with parameters relevant to the scrape-off layer of confined
toroidal plasmas. Strongly intermittent plasma transport is regulated by
self-consistently generated sheared poloidal flows and is mediated by bursty
ejection of particles and heat from the bulk plasma in the form of blobs.
Coarse grained probe signals reveal a highly skewed and flat distribution on
short time scales, but tends towards a normal distribution at large time
scales. Conditionally averaged signals are in perfect agreement with
experimental measurements.
