What is convergence and divergence in meteorology?
convergence and divergence, in meteorology, the accumulation or drawing apart of air, as well as the rate at which each takes place. The terms are usually used to refer specifically to the horizontal inflow (convergence) or outflow (divergence) of air.
What is convergence in meteorology?
A convergence zone in meteorology is a region in the atmosphere where two prevailing flows meet and interact, usually resulting in distinctive weather conditions. This causes a mass accumulation that eventually leads to a vertical movement and to the formation of clouds and precipitation.
What does divergence mean in geography?
[ dĭ-vûr′jənt ] A tectonic boundary where two plates are moving away from each other and new crust is forming from magma that rises to the Earth’s surface between the two plates.
What do divergent winds cause?
This causes air to diverge, or move away, from the center of the high near the ground. Air has to come from above to fill in the void left by the diverging air at the surface. This leads to sinking motion in the center of a high pressure system and generally clear air.
What is diverge science?
In evolutionary biology, divergence pertains to an evolutionary process wherein a population of an inbreeding species diverges into two or more descendant species that have become more and more dissimilar in terms of forms and structures.
What is a divergent series in math?
In mathematics, a divergent series is an infinite series that is not convergent, meaning that the infinite sequence of the partial sums of the series does not have a finite limit. If a series converges, the individual terms of the series must approach zero.
Is high pressure convergent or divergent?
Surface high pressure systems in the Northern Hemisphere have a clockwise rotation with wind turning slightly outward away from the highest pressure. This causes air to diverge, or move away, from the center of the high near the ground.
What does divergent mean in science?
Divergent (Spreading):This is where two plates move away from each other. Molten rock from the mantle erupts along the opening, forming new crust.
What are convergent winds?
Convergence in a horizontal wind field indicates that more air is entering a given area than is leaving at that level. To compensate for the resulting “excess,” vertical motion may result: upward forcing if convergence is at low levels, or downward forcing (subsidence) if convergence is at high levels.
What does divergent mean in biology?
Divergent evolution refers to the process by which interbreeding species diverged into two or more evolutionary groups. It means that these groups of species used to be similar and related. However, they became more and more dissimilar through time.
