Orographic effects on tornadic supercell development, propagation, and structure are investigated using the Cloud Model 1 with idealized bell-shaped mountains of various heights and geometries and a homogeneous fluid flow with a single sounding. In total, the variations of height and geometry yield 16 terrain configurations. It is found that blocking effects are dominative compared to the terrain-induced environmental heterogeneity downwind of the mountain. The isolated bell-shaped mountains tended to shift the track of the storm towards the left of storm motion; however, when the terrain was elongated the effect tended to be rightward. The terrain blocking effect also enhanced …

Volatile organic compound(s), VOC(s), detection have become a highly demanding area of research due to potential harmful effects to the ecosystem. The search for methods of VOC sensor devices has led to the examination of photoluminescence and photoluminescent materials such as metal complexes. Their luminescent properties markedly with phosphine and/or nitrogen based ligands, bridging ligands, have the ability to accommodate metal atoms with short metal – metal distances. It is of great interest to accomplish short metal interactions as the photoluminescent properties can be altered. We show the synthesis and structural characterization of the bridging ligand, 1-methylbenzimidazole diphenylphosphine. We examined …
