Sub Vortex

Nov 23, 2014 - 9:33 PM - by Caleb Routt
So question.. How do sub vorticies form in a tornado? Is it the same way that suction vorticies develop? And how do some of them stay persistent like the ones did on El Reno?

In the new study, published today in Science, Brooks and his colleagues tallied U.S. storms from 1954 to 2013, leaving out the small F0 twisters. Then they looked at the days on which those storms occurred. They found that the frequency of tornado days has

12Z NAM for this morning is still rolling in but this day is finally within a reasonable range to make a forecast thread about.

To All,

Something that has always bothered me to no end is the potential damage that an upper-EF scale tornado would do to an urban area such as downtown OKC. The May, 31st 2013 monster could have impacted the downtown OKC area if it had stayed on the ground. My biggest question would be, taking into consideration the funneling effect of channeling winds through a venturi, what kind of wind speeds would be possible with a tornado such as this one? Also, could a tornado of... [Read More]

Things are shaping up for a potentially near-record lake effect snow event off the east ends of Lakes Erie and Ontario from tonight into Wednesday. Lapse rates will be steep with temps as low as -40C at 500mb above the still fairly-warm lakes. NWS Buffalo is expecting 3-5 inch-per-hour accumulations at times in the heaviest bands, and thundersnow is a good bet with this event. Some areas could see 2-3 feet, with another lake effect event likely coming quickly on the heels of this one late in... [Read More]
