On a weather map where isobars are closely spaced, the Description pressure gradient is relatively _______ and winds are Course Schedule rela-tively _______. Grading steep...strong Learning weak...strong Objectives steep...weak Photographs weak...weak Practice Questions 2. Horizontal gradients in air pressure are caused by Special Notice horizontal gradients in air temperature. Student horizontal gradients in water vapor concentration. Responsibilities divergence or convergence of winds. Any of the above is correct. Access to Online Daily Weather 3. Air pressure is higher in the _______ than the Summary and _______. Learning troposphere...mesosphere Activities heterosphere...homosphere ionosphere...stratosphere National Weather thermosphere...mesosphere Service - Green Bay 4. All other factors being equal, air flows from regions of relatively _______ pressure toward regions of Home relatively _______ pressure. high...low low...high 5. The centripetal force is a center-seeking force. operates when the wind describes a curved path. arises from the action of other forces. All of the above are correct. 6. The magnitude of the Coriolis effect is maximum at _______ and zero at _______. the equator...45 degrees latitude the poles...the equator Miami...Chicago 0 degrees latitude...the North Pole 7. In the Northern Hemisphere, the Coriolis effect causes an east wind to become a _______ wind. northeast west southeast northwest 8. In the Southern Hemisphere, the Coriolis effect causes a west wind to become a _______ wind. southwest northwest east southeast 9. At the equator, the Coriolis effect causes an east wind to become a _______ wind. southeast northeast west None of the above is correct. 10. The effect of friction on wind speed and direction is great-est in the stratosphere. upper troposphere. lower troposphere. heterosphere. 11. Hydrostatic equilibrium is the balance between _______ and _______. centripetal force...friction the Coriolis effect...gravity gravity...vertical pressure gradient force centripetal force...the Coriolis effect 12. Curved horizontal wind above the friction layer is the _______ wind. geostrophic hydrostatic gradient surface 13. Forces are _______ in the geostrophic wind and _______ in the gradient wind. balanced...balanced balanced...unbalanced unbalanced...balanced unbalanced...unbalanced 14. Unaccelerated, horizontal, and frictionless flow: gradient wind hydrostatic equilibrium geostrophic wind surface winds 15. In the Northern Hemisphere viewed from above, surface winds in a _______ blow counterclockwise and inward. cyclone anticyclone 16. A cyclone is a _______ weather system whereas an anticyclone is a _______ weather system. fair...stormy stormy...fair 17. In the Southern Hemisphere viewed from above, surface winds in an anticyclone blow clockwise and parallel to isobars. counterclockwise and outward. clockwise and outward. counterclockwise and parallel to isobars. 18. Nocturnal radiational cooling is most intense at the center of an anticyclone. at the center of a cyclone. well to the east of an anticyclone. when the sky is cloud-covered. 19. Radiation fog is most likely when a region is under the influence of a(n) cyclone. anticyclone. 20. Dew or frost is most likely when a region is under the influence of a(n) cyclone. anticyclone.
