Double Compressions of Atmospheric Depth by Geopotential Tendency, Vorticity, and Atmospheric Boundary Layer Affected Abrupt High Particulate Matter Concentrations at a Coastal City for a Yellow Dust Period in October by Hyo Choi, Mi Sook Lee

“…Positive geopotential tendency at the 500 hPa level of the city (∂Φ/∂t; m day−1) corresponding to negative vorticity of -4×10-5 sec−1 (-2.5×10-5 sec−1) at 0900 LST (21:00 LST; at night) was +83 m day−1 (+30 m day−1) and it caused atmospheric depth between 500 hPa level and the ground surface to be vertically expanded. …”

Numerical Investigation of Unsteady Cavitation Flow around E779A Propeller in a Nonuniform Wake with an Insight on How Cavitation Influences Vortex by Chengzao Han, Yun Long, Xiaorui Bai, Bin Ji

“…The unsteady behavior of cavitation and side-entrant jet can both promote local vorticity generation and flow unsteadiness. In addition, it is indicated with the relative vorticity transport equation that the stretching term plays a major role in vorticity transportation, while baroclinic torque and Coriolis force term mainly influence the vorticity distribution along the liquid-vapor interface.…”

Early Detection of Baby-Rain-Cell Aloft in a Severe Storm and Risk Projection for Urban Flash Flood by Eiichi Nakakita, Hiroto Sato, Ryuta Nishiwaki, Hiroyuki Yamabe, Kosei Yamaguchi

“…Additionally, to resolve the relationship between baby-rain-cell growth and vorticity behavior, we carried out an analysis of vorticity inside baby-rain-cells and verified that a pair of positive and negative vertical vortex tubes as well as an updraft between them existed in a rain-cell in the early stage.…”
