HODOGRAPHS, BUOYANCY, COLD POOL/SHEAR INTERACTIONS - IMPORTANT CONCEPTS AND QUESTIONS

  1. What is a hodograph and how is vertical wind shear represented?
  2. Draw a vertical wind profile that would produce a straight hodograph?
  3. What kind of wind profile woud produce a clockwise hodograph?
  4. How does one estimate storm motion of an ordinary cell with the hodograph?
  5. What is buoyancy? Units?
  6. what contributes to positive and/or negative buoyancy?
  7. How is buoyancy related to CAPE? What is CAPE? What assumptions are made when calculating CAPE?
  8. Discuss the relationship between downdraft strength and the wet bulb potential temperature.
  9. What factors contribute to stronger updrafts and downdrafts?
  10. Discuss the physical processes that lead to vorticity generation.
  11. Discuss how cold pool/shear interaction leads to preferential lifting of parcels on the down-shear flank of a circular cold pool.
  12. What is the significance of C = delta U?
