Concerns Regarding Severe Deep Moist Convection
Buoyancy is key to thunderstorm growth and is necessary for any of the severe threats within a thunderstorm. There are other processes, not necessarily thermodynamic, that can increase updraft strength. These include updraft rotation, low level convergence, and evacuation of mass out of the top of the updraft via strong upper level winds and the jet stream.

Famous quotes containing the words concerns, severe, deep and/or moist:
“In what concerns you much, do not think that you have companions: know that you are alone in the world.”
—Henry David Thoreau (1817–1862)
“Authors have established it as a kind of rule, that a man ought to be dull sometimes; as the most severe reader makes allowances for many rests and nodding-places in a voluminous writer.”
—Joseph Addison (1672–1719)
“Affection, indulgence, and humor alike are powerless against the instinct of children to rebel. It is essential to their minds and their wills as exercise is to their bodies. If they have no reasons, they will invent them, like nations bound on war. It is hard to imagine families limp enough always to be at peace. Wherever there is character there will be conflict. The best that children and parents can hope for is that the wounds of their conflict may not be too deep or too lasting.”
—New York State Division of Youth Newsletter (20th century)
“Spindly branches of buttercups were secreted among gleaming stems still moist at the roots from last night’s rain that had washed and refreshed the entire wood, had dowered it in poignant transparency, the unique, inconsolable quality of rainy countries, as if all was glimpsed through tears.”
—Angela Carter (1940–1992)
