Validation Of Solar Flare Forecasting & Evolution Of Magnetic Helicity Of Two Active Regions, Qin Li
Theses
This thesis includes two components: (1) Validation of the NJIT flare-forecasting model that was established in recent years is carried out based on the statistical correlation between solar magnetic parameters and flare productivity of active regions (ARs). 378 ARs are examined, comparing observation with prediction. It is found that the accuracy rate to some extent decreases with the level of flares. (2) The temporal evolution of the relative magnetic helicity of two ARs, AR 11072 and 11158 is investigated. The former is flare-quiet while the latter is flare-productive over the 5-day observation period. It is found that for both regions, …
