| The ingredients were classic
Throw in wind shear ― when winds at different levels in the atmosphere blow in different directions ― frame explosion proof motor and you might get enough twisting convection currents to produce super-cell thunderstorms. These, in turn, can spawn tornados. This year, the winds from the Gulf of Mexico have been "exceptionally warm and humid for this early in the spring," Ostro said. Those warm winds from the south blew close to the ground this week while a very strong jet stream came in from the west higher up. "The ingredients were classic, and extreme," Ostro said. Weiss said conditions favorable for tornadoes also extended over a very wide portion of the eastern third of the U.S., from Mississippi, where the storms originated, east to the mid-Atlantic coast and into the Ohio River Valley, reaching as far north as frame explosion proof motor far as Indianapolis. That allowed the storm system to thrive, and it may account for the widespread devastation on the ground, he said. The role of global warming in the phenomenon is unclear, he added, noting that it's hard to relate individual weather events to the long-term sweep of climate change, and that even if one could,Tinnitus, there's "significant debate" in the scientific literature about whether warming will increase or decrease the number of tornadoes. By Thursday afternoon, the storm system had edged into the Atlantic Ocean, and the danger of frame explosion proof motor additional tornados had subsided. Over the coming months, Carbin said, the National Weather Service will study the destruction to plot the twisters' paths and intensity, assigning them ratings from 0 to 5 on the Enhanced Fujita Scale. Three-second gusts at 65 to 85 mph are rated EF-0; twisters with gusts over 200 mph are rated EF-5.
