Forms
There are two primary forms of atmospheric instability:
- Convective instability
- Dynamic instability (fluid mechanics)
Under convective instability thermal mixing through convection in the form of warm air rising leads to the development of clouds and possibly precipitation or convective storms. Dynamic instability is produced through the horizontal movement of air and the physical forces it is subjected to such as the Coriolis force and pressure gradient force. Dynamic lifting and mixing produces cloud, precipitation and storms often on a synoptic scale.

Famous quotes containing the word forms:
“Pervading nationalism imposes its dominion on man today in many different forms and with an aggressiveness that spares no one.... The challenge that is already with us is the temptation to accept as true freedom what in reality is only a new form of slavery.”
—Pope John Paul II (b. 1920)
“When we speak the word “life,” it must be understood we are not referring to life as we know it from its surface of fact, but to that fragile, fluctuating center which forms never reach.”
—Antonin Artaud (1896–1948)
“Painting dissolves the forms at its command, or tends to; it melts them into color. Drawing, on the other hand, goes about resolving forms, giving edge and essence to things. To see shapes clearly, one outlines them—whether on paper or in the mind. Therefore, Michelangelo, a profoundly cultivated man, called drawing the basis of all knowledge whatsoever.”
—Alexander Eliot (b. 1919)
