Examples of Using TORNADOGENESIS in a Sentence

• While a severe thunderstorm watch does not nominally imply the probability for tornadoes, if modest wind shear and storm-level helicity is conducive for a marginal tornado threat within the convective environment, storm cells that develop within the proximate severe thunderstorm watch area can occasionally exhibit mesocyclonic rotation at the cloud base and may spawn tornadoes if advanced tornadogenesis occurs.
• Typically, when one tornado weakens and another forms, the process of successive parent mesocyclones forming and decaying is known as cyclic tornadogenesis, thus leading to a series of tornadoes spawned by the same supercell.
• The specific characteristics of the Southeast led to VORTEX-SE, a field project studying tornadogenesis, diagnosis and forecasting, in addition to social science implications, and examines both supercellular tornadoes and those resulting from quasi-linear convective system (QLCS) thunderstorm structures.
• Przybylinski was a leading expert on quasi-linear convective systems (QLCS), bow echoes, and mesoscale convective systems (MCSs), and convective winds and tornadogenesis associated with these thunderstorm structures.
• The hook echo feature is formed as the RFD occludes precipitation around the mesocyclone and is also indicative of a probable tornado (tornadogenesis usually ensues shortly after the RFD reaches the surface).
• Local Weather Forecast Offices (WFO) of the National Weather Service may issue a Special Weather Statement to alert of a specified hazard that is approaching or below warning or advisory criteria, that does not have a specific alert product code of their own (such as for widespread funnel clouds with limited to no threat of complete tornadogenesis, the likelihood of landspouts, or strong outflow winds from decaying thunderstorms), to advise of ongoing or imminent hazardous convective weather expected to occur within the geographical area over a one- to two-hour timeframe, major events forecast to occur beyond a six-hour timeframe (such as substantial temperature changes, dense fog and winter weather events), or to outline high-impact events supplementary to information contained in other hazardous weather products (such as black ice, short-duration heavy snow or lake-effect snow bands expected to briefly reduce visibility, heavy rainfall not expected to cause flooding, heat index or wind chill values expected to approach "advisory" criteria for one or two hours, or local areas of blowing dust where wind is below advisory criteria).
• A tornadic vortex signature, abbreviated TVS, is a Pulse-Doppler radar weather radar detected rotation algorithm that indicates the likely presence of a strong mesocyclone that is in some stage of tornadogenesis.
• MCVs, like mesovortices, often cause an intensification of convective downburst winds and can lead to tornadogenesis.
• Markowski is an American meteorologist and leading expert on tornadogenesis and the forecasting of supercells and tornadoes.
• He was a significant collaborator in seminal research on tornadogenesis, specifically the importance of baroclinic boundaries, the rear-flank downdraft (RFD) and its thermodynamic characteristics.
• Tornadogenesis can occur because of a supercell thunderstorm, a waterspout, a landspout, or a fire whirl, and can happen in any month of the year.
