Numerical simulations are used to study transitions between boundary layer rolls and more cellular convective structures observed during a lake-effect snow event over Lake Michigan on 17 December 1983. Weak lakeeffect nonroll convection was observed near the eastern (downwind) shore preceding passage of a secondary cold front. After frontal passage(More)
Boundary layer rolls over Lake Michigan have been observed in wintertime conditions predicted by many past studies to favor nonroll convective structures (such as disorganized convection or cellular convection). This study examines mechanisms that gave rise to transitions between boundary layer rolls and more cellular convective structures observed during a(More)
For applications such as 3D integration, flip chip, and other die interconnection processes, a variety of metals is used to form an electrical and mechanical bond between the two components. Native oxides, however, quickly form on many of the common bond materials, hindering the integrity of the joint and adversely affecting long-term reliability. A new(More)
