VORTEX2 was an expanded second VORTEX project, with field phases from 10 May until 13 June 2009 and 1 May until 15 June 2010. VORTEX2's goals were studying why some thunderstorms produce tornadoes while others do not, and learning about tornado structure, in order to make more accurate tornado forecasts and warnings with longer lead time.

The Lambda2 method, or Lambda2 vortex criterion, is a vortex core line detection algorithm that can adequately identify vortices from a three-dimensional fluid velocity field. [1] The Lambda2 method is Galilean invariant , which means it produces the same results when a uniform velocity field is added to the existing velocity field or when the ...
The TWISTEX crew and the vehicles on equipped with mobile mesonets. TWISTEX (a backronym for Tactical Weather-Instrumented Sampling in/near Tornadoes Experiment) was a tornado research experiment that was founded and led by Tim Samaras of Bennett, Colorado, US, that ended in the deaths of three researchers in the 2013 El Reno tornado.
A Scientific Industries Inc. Vortex-Genie 2 vortex mixer in operation A vortex mixer , or vortexer , is a simple device used commonly in laboratories to mix small vials of liquid. It consists of an electric motor with the drive shaft oriented vertically and attached to a cupped rubber piece mounted slightly off-center.
Australia's full legislature has now passed a bill that will soon ban children under the age of 16 from using most social media platforms.
The Vortex lattice method, (VLM), is a numerical method used in computational fluid dynamics, mainly in the early stages of aircraft design and in aerodynamic education at university level. The VLM models the lifting surfaces, such as a wing , of an aircraft as an infinitely thin sheet of discrete vortices to compute lift and induced drag .
Neither the United States nor China would win a trade war, the Chinese Embassy in Washington said on Monday, after U.S. President-elect Donald Trump threatened to slap an additional 10% tariff on ...
