Solar bursts are analyzed at 22 and 44 GHz with 0.03 sfu (rms) sensitivity and 1 mm resolution, and with 100 ms resolution at 7 GHz. Burst maximum emission is found to not coincide in time at those frequencies, in most cases, with time delays ranging from 3 s to near coincidence (defined within 10 ms). Some complex bursts presented a variety of delays among different time structures, and sometimes nearly uncorrelated time structures. Large time delays are found to favor the association of the dynamic effects with shock wave speeds. Directional particle acceleration in complex magnetic configurations may be invoked to explain the variety of dynamic effects found. The fastest burst rise times observed at 44 and 22 GHz may be associated with limiting emission source formation times combined with absorption mechanisms at the source and surrounding plasma.
