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:
“The difference between de jure and de facto segregation is the difference open, forthright bigotry and the shamefaced kind that works through unwritten agreements between real estate dealers, school officials, and local politicians.”
—Shirley Chisholm (b. 1924)
“If I had any doubts at all about the justice of my dislike for Shakespeare, that doubt vanished completely. What a crude, immoral, vulgar, and senseless work Hamlet is. The whole thing is based on pagan vengeance; the only aim is to gather together as many effects as possible; there is no rhyme or reason about it.”
—Leo Tolstoy (1828–1910)
