By 0011 UTC (Figure 3(c)), the new SRFGF had surged westward, overtaking the old outflow region, as the RFD strengthened (Figure 3(d), x = -54, y = 27) and the low-level updraft zone and vertical vorticity field became better organized (Figures 3(b) and 3(d)).
Evolution of Vertical Vorticity. Initially at 2358 UTC, the developing low-level mesocyclone vortex (Figure 3(b), x = -53, y = 25) was small, symmetric, and collocated with an updraft while also decreasing in size with height (Figure 4(b)).
A mesocyclone usually possesses a diameter between 2 and 10 km and a vertical vorticity on the order of 0.01 [s.sup.-1] or greater (American Meteorological Society 2016).
Further, Section 3 describes a method for identifying hazardous rain-cells that may cause Guerrilla-heavy rainfalls using vertical vorticity values inside rain-cells obtained by Doppler radar observation.
The results of this new article probably at least partly explain why.--Paul Markowski (Penn State University) and Yvette Richardson, "Large sensitivity of near-surface vertical vorticity development to heat sink location in idealized simulations of supercell-like storms," in a forthcoming issue of the Journal of the Atmospheric Sciences.
The right split storm exhibits strong positive vertical vorticity at the beginning of the period with a weaker anticyclonic counterpart on the northwest side of the mesocyclone.
(2014) simulated a tornadic supercell using ARPS in which the tilting of frictionally generated horizontal vorticity was cited as an important source of near-ground vertical vorticity. In Schenkman et al.
The conditions associated with tornadoes have been extensively studied and include contributions from an environment conducive to deep moist convection and a source of easily stretched low-level vertical vorticity (Doswell et al.
Both the secondary and tertiary eyewalls contracted with time, as clearly illustrated in the time-evolution of axisymmetric reflectivity, tangential winds, and vertical vorticity fields (Fig.
Figure 6 indicates that the horizontal flow relative to the translating MV is filled with positive vertical vorticity peaking at about 12 x [10.sup.-3] [s.sup.-1] at the lowest analysis level of 1 km AGL.
