What is the difference between a shelf cloud and a wall cloud?

Hurricane development is less likely when pre existing upper level winds are...?

• I need help with meteorology...if anyone can help. 1. Hurricane development is less likely when preexisting upper-level winds are [STRONG or WEAK]. 2. Tropical cyclone development is most likely in a region where surface winds [CONVERGE or DIVERGE]. 3. Hurricanes are [WARM or COLD] core lows. 4. In a hurricane are the fastest winds and the strongest thunderstorms found closer to the [CENTER or OUTER EDGE] of the storm. 5. Cloud seeding has been used in attempts to [INCREASE or DECREASE] the diameter of the eye wall and thereby weaken hurricanes. 6. In a hurricane moving northward along the Atlantic coast of the US, the strongest winds will be on the [EAST or WEST ] side. 7. From 1953 to 1977, the Weather Service used just [MALE or FEMALE] names for hurricanes. 8. In most tropical regions the seasons are marked by differences in [TEMPERATURE or PRECIPITATION]. 9. The temperature difference between the ocean and the cloud top determines the maximum strength of a storm in the [HEAT ENGINE or ORGANIZED CONVECTION] representation of a hurricane. 10. If a hurricane remains over warm water of sufficient depth, it may survive for several weeks. [TRUE or FALSE] 11. Lows that develop over polar waters during the winter exhibit many of the characteristics of a hurricane and are sometimes referred to as Arctic hurricanes. [TRUE or FALSE] 12. Despite there being many differences in structure, if a weakening hurricane links up with an upper-level trough it may actually become a mid-latitude cyclone. [TRUE or FALSE] 13. Statistical models that compare a present hurricane with similar storms in the past have been very successfully used to forecast changes in a hurricane’s intensity. [TRUE or FALSE] 14. Most hurricanes develop in warm tropical waters at the equator even though the Coriolis force is zero there. [TRUE or FALSE] 15. The terms typhoon and cyclone refer to the initial weaker stages in the development of a hurricane. [TRUE or FALSE] 16. Considerable damage may be caused by [MICROBURSTS or TORNADOES] that tend to form in the right front quadrant of an advancing hurricane. 17. The clear eye in the center of a hurricane is produced by [RISING or SINKING] air. 18. The eye wall is a ring of intense [THUNDERSTORMS or SPIRAL BANDS] that surround the center of a hurricane. 19. Hurricanes derive their energy from transfer of sensible and [CONVECTIVE or LATENT or CONDUCTIVE] heat from warm tropical oceans into the atmosphere. 20. The storm surge can be especially damaging when it coincides with [LOW or HIGH] tide. 21. Streamlines are used on weather maps for the tropics because [TEMPERATURE or PRESSURE] varies so little in this region. 22. Hurricanes in the North Pacific are termed [CYCLONES or TYPHOONS]. 23. A convection profile half way across the diameter of a typical hurricane, at the surface, would find [DESCENDING or ASCENDING] air at the outer edge, strong advection flow [TOWARD or AWAY FROM] the eye, [DESCENDING or ASCENDING] air in the eye wall and [DESCENDING or ASCENDING] air in the eye. Within the advection region one would find [SPIRAL BANDS or STRAY EYES] caused by regions of [SINKING or RISING or ALTERNATING RISING & SINKING] air. {6 answers} 24. A hurricane moving due west will have its strongest winds on the [NORTHERN or SOUTHERN] side of the storm; as the storm moves along one would expect the storm to curve to the [RIGHT or LEFT] due to Coriolis force. {2 answers} 25. Hurricane Zeke is head due north up the Florida west coast. The strongest winds will be on the [LANDWARD or SEAWARD] side of the storm. A cold front lies across the state from Daytona to Tampa. One would expect Zeke to [CONTINUE NORTH UP THE COAST or CURVE AND FOLLOW THE FRONT NORTHEASTWARD ACROSS THE STATE or STALL AND BACK UP OVER THE KEYS].{2 answers} 26. Most damage caused by hurricanes is due to [HIGH WINDS or HIGH WAVES or STORM SURGE or HEAVY RAIN]. 27. Hurricanes Lum (Category 2) is following closely in the path of Hurricane Jake (Category 4). A very possible result might be that Lum will die out because [Jake chilled the seawater along Lum’s path OR out flow aloft from Jake disturbed the upper air flow in Lum OR Jake chilled the seawater path and it’s outflow broke Lum apart aloft].

• Answer:

  1. Strong 2. converge 3. warm 4. center 5. increase (to disrupt angular momentum) 6. east (Velocity + Translational considered) 7. female 8. precipitation 9. heat engine (aka Carnot engine) 10. true 11. true 12. true ( a nearly perfect analogue to this is Hurricane Wilma in October 2005) 13. true (SHIPS model is mainly stat driven) 14. false 15. false 16. tornadoes 17. sinking (subsidence) 18. thunderstorms 19. Latent 20. high tide (the water is at a higher starting point) 21. pressure (since streamlines are pressure related) 22. typhoons 23. descending, toward, ascending, descending ...not sure on others... 24. northern, right (to the right in north hemisphere) 25. landward, follow the front northeast across the state 26. storm surge 27. Option 3 I hope this helps you! I had fun with this!
