Fisher, George 95-28474 Dr. Fisher will study how magnetic flux emerges from the solar interior, where it is generated, to the surface, where it is observed. Theoretical models of flux emergence based on the flux tube paradigm have been tremendously successful in explaining many properties of active region magnetic fields. These models will be improved in three ways -- first, to improve the treatment of the velocity field on rising flux to include turbulent and meridional flows; second, to include twists in emerging fields to account for certain strange active regions and flaring; third, to include fragmentation of rising flux and more carefully treat submerging flux. ***

费希尔博士将研究磁通量是如何从太阳内部（它是在那里产生的）到表面（它是在那里被观察到的）出现的。基于磁通管范式的磁通产生的理论模型在解释有源区磁场的许多性质方面取得了巨大的成功。这些模型将在三个方面得到改进：第一，改进对上升通量的速度场的处理，包括湍流和经向流；第二，包括新兴领域的扭曲，以解释某些奇怪的活跃区域和耀斑；第三，包括上升通量的破碎化，更仔细地处理下沉通量。＊＊＊
