In this thesis, we present results from a detailed analysis of temporal profiles and spatially resolved hard X-ray images from RHESSI alongside high cadence observations of the UV continuum from TRACE for two solar flares: A C6.5 flare from 16 July 2002 06:38--06:43 UT and an M8.5 flare from 17 July 2002 07:00--07:05 UT. For both flares we find a significant temporal correlation between the UV and hard X-ray emission over the duration of both events. In the spatial analysis for the 16 July 2002 event, we note a significant spatial separation between the correlated UV sources and their hard X-ray counterparts leading to a complex flare topology invoking loop-loop interactions. We suggest a three-dimensional reconnection scenario in an attempt to address the spatial discrepancy in the hard X-ray and UV correlated emission.96 p.application/pdfengCopyright is held by the author, unless otherwise indicated.
