Juno discovered the circumpolar cyclones polygons on Jupiter in 2017. Fundamental questions regarding Jovian cyclogenesis concern formation mechanism and whether these are deep or shallow. Recent data by Juno/JIRAM infrared camera show that any change is an extremely unlikely event annual scale. Only once, 2019, a sixth cyclone joined pentagonal structure South, but it disappeared after 2 month...

Abstract. In this study, we address the question of atmospheric processes that turn Mediterranean cyclones into severe storms. Our approach applies online potential vorticity (PV) budget diagnostics and piecewise PV inversion to WRF model simulations mature stage 100 intense cyclones. We quantify relative contributions different cyclone development therefore deliver, for first time, a comprehen...

In this paper the numerical simulation of flow field in the new design dynamic cyclone separator is investigated. The effects of different geometrical parameters such as impeller diameter, number of vanes, length and the location of impeller is investigated. The Reynolds averaged Navier–Stokes equations with Reynolds stress turbulence model (RSM) were solved. The Eulerian-Lagrangian computation...

The use of QuikSCAT data for wind retrievals of tropical cyclones is described. The evidence of QuikSCAT 0 dependence on wind direction for 30-m/s wind speeds is presented. The QuikSCAT 0 show a peak-to-peak wind direction modulation of 1 dB at 35-m/s wind speed, and the amplitude of modulation decreases with increasing wind speed. The decreasing directional sensitivity to wind speed agrees wel...
