Why do nearly all hurricanes form in the equatorial regions of the earth?
| There is stronger vorticity near the equator. | |
| The Coriolis force is the strongest in these areas. | |
| Vertical wind shear is the greatest in these areas. | |
| These areas have the largest source of warm water. |
In which direction does horizontal air flow in a hurricane?
| Clockwise throughout the entire vertical depth of the storm | |
| Counter-clockwise throughout the entire vertical depth of the storm | |
| Clockwise at the surface, counter-clockwise aloft | |
| Counter-clockwise at the surface, clockwise aloft |
Cyclones
| are typically regions of fair weather | |
| are associated with supergeostrophic winds | |
| experience Coriolis effects that deflect air to the east in the Southern Hemisphere | |
| are associated with low-pressure systems |
Over the Indian Ocean, what are the strongest tropical storms called?
| Typhoons | |
| Hurricanes | |
| Cyclones | |
| Inta’akas |
What is true of jet streams?
| They are easy for meteorologists to track. | |
| They have typical speeds around 50 km/hr. | |
| They are very turbulent. | |
| They do not change much in intensity over the course of a year. |
In the northern hemisphere, tornadoes most often form in the ________ quadrant of a hurricane.
| southeast | |
| northeast | |
| southwest | |
| northwest |
What is true of anticyclones?
| They are associated with subgeostrophic winds. | |
| They have air spiraling into them at lower elevations. | |
| They have clockwise winds in the Northern Hemisphere. | |
| They do not have winds in the upper atmosphere that follow height contours. |
