Local Effects
Low-level outflow boundaries from thunderstorms are cooler and more moist than the air mass the thunderstorm originally formed within due to its wet bulbing by rain, forming a wedge of denser air which spreads out from the base of the parent thunderstorm. If wind speeds are high enough, such as during microburst events, dust and sand can be carried into the troposphere, reducing visibility. This type of weather event is known as a haboob, and is most common in the late spring within Sudan. Upper-level outflow can consist of thick cirrus clouds which would then obscure the sun and reduce solar insolation around the outermost edge of tropical cyclones.

Famous quotes containing the words local and/or effects:
“Back now to autumn, leaving the ended husk
Of summer that brought them here for Show Saturday
The men with hunters, dog-breeding wool-defined women,
Children all saddle-swank, mugfaced middleaged wives
Glaring at jellies, husbands on leave from the garden
Watchful as weasels, car-tuning curt-haired sons
Back now, all of them, to their local lives....”
—Philip Larkin (1922–1986)
“Virtues are not emotions. Emotions are movements of appetite, virtues dispositions of appetite towards movement. Moreover emotions can be good or bad, reasonable or unreasonable; whereas virtues dispose us only to good. Emotions arise in the appetite and are brought into conformity with reason; virtues are effects of reason achieving themselves in reasonable movements of the appetites. Balanced emotions are virtue’s effect, not its substance.”
—Thomas Aquinas (c. 1225–1274)
