In this paper we characterize the singularity spectrum, f (a), for solar bursts observed at 1.6, 2.0 and 3 CHz. We interpret our findings as evidence of inhornogeneous plasma turbulence driving the underlying plasma emission process and discuss the nonlinear multifractal approach into the context of geoeffective solar active regions.
