B) The cyclone has sucked up all the moist air around it,leaving dry air behind.

Accepted Answer

A) A strong jet stream flow must be present to maintain the inward flow. 
B) A strong divergent flow (outflow)aloft must keep up with,or exceed,the inflow near the surface. 
C) The storm must push the tropopause far into the stratosphere to maintain the low pressure. 
D) Rain must fall to force thunderstorms to collapse to keep the air circulation going.

Question 8

Asia has an intense monsoon,but North America also experiences a low-intensity monsoon.What causes monsoons?

Accepted Answer

A) Heating of the polar regions in summer due to long days causes air to flow toward the poles in summer,drawing moisture from warm ocean dominated air masses. 
B) The heating of the continent during the summer produces a persistent low pressure over the continent that draws warm moist air masses from adjacent oceans. 
C) The oceans warm faster than the continents during the summer and spawn cyclonic storms that move toward the continents. 
D) The horse latitude high pressure system breaks down in summer,leading to monsoon moisture in desert locations like southwestern North America and India.

Question 9

Which of the following is not true for anticyclonic storms systems in the Northern Hemisphere?

Accepted Answer

A) The outward flow produces a clockwise circulation due to the Coriolis force. 
B) The storm system is characterized by high pressure and descending air. 
C) The storm system is characteristic of mid-latitude zones and is typically associated with fair weather. 
D) The storm system is a low-latitude phenomena associated with outflow from tropical cyclones.
