SEVERE STORM STRUCTURE: ANVIL .. METEOROLOGIST JEFF HABY
The Anvil is one of the most impressive features of a severe storm due to its areal coverage and icy texture. Within a severe storm, moisture is transported from the lower troposphere to deep into the upper troposphere. Not all moisture that is ingested into a storm is precipitated out of the storm. Some of the moisture in a strong updraft is lofted so high into the troposphere that it is not able to drop back down immediately. Strong upper level winds move and fan the moisture out over great distances. The temperature of the anvil is frigid cold. The light density of the moisture allows the wind to move it at will. A forecaster can note the direction and speed of the upper level winds by noting the anvil's orientation. The moisture within the anvil will be blown downstream. On the diagram below, "A" denotes the anvil.

What is wind shear?
Wind shear refers to a change in wind speed or direction with height in the atmosphere.
Wind shear can also refer to a rapid change in winds over a short horizontal distance experienced by aircraft, conditions that can cause a rapid change in lift, and thus the altitude, of the aircraft.
Some amount of wind shear is always present in the atmosphere, but particularly strong wind shear Wind shear is important for the formation of tornadoes and hail.
Larger values of wind shear also exist near fronts, extratropical cyclones, and the jet stream.
Wind shear in an atmospheric layer that is clear, but unstable, can result in clear air turbulence.
Interesting facts:
MAKING AIR TRAVEL SAFER Many airports now have wind shear detection equipment near the ends
of runways to warn aircraft if it is too dangerous to land. .. (page last updated 11/28/2010)
