What is Westward intensification and what causes it?



Answer: Currents flowing from West to East at higher latitudes (in either hemisphere!) have water deflected more quickly and strongly towards the center of the gyre than currents flowing form high latitudes towards the equator because the Coriolis force is greater near the poles. This leads to an asymmetrical gyre and explains why western boundary currents are fast and deep while easter boundary currents are the opposite

Although early research identified several unique features of the grapevine, some of these features may be changing as the Internet plays an increasing role in grapevine communication.

Examine the age-structure diagrams of Sweden and Kenya below, and answer the following questions.   Compare and contrast the two age structure diagrams in terms of two population dynamics - birth rate and death rate. Restatement: Given two age-structure diagram, Sweden and Kenya for 2000, compare and contrast the diagram in terms of population dynamics.  Age structure diagrams are basically divided into three major age categories: 1) Prereproduction (0-15 years old) 2) Reproductive (16-45 years old) 3) Postreproduction (46 years old-death) Birth Rate Sweden  1) Population has nearly equal proportions of pre-reproductive and reproductive individuals. 2) Little growth over a long period of time will produce a population with about equal numbers of people in all age groups. 3) Children not required or necessary to support parents.  4) Availability and acceptance of birth control. Kenya 1) Population had pyramid-shaped age structu...
