ATSC 113 Final Exam Questions with Verified Answers

ATSC 113 Final Exam Questions with Verified Answers Warm front - Answer-Easterly ahead southerly behind, Wind ahead is cool & humid. Associated w/ Stratiform clouds ahead. Alongside, extensive low clouds & fog. Weak T gradient Gradual T increase may change the precipitation Reduced vis & thick clouds/fog TS - Answer-Convective clouds driven by buoyancy of warm rising air. Most common in spring & summer. Stay at least 20 nm away. TS cells - Answer-*Each is an individual TS. 1) Cumulus: updraft, no rain, no anvil, not vis on radar. 2) mature: up & down drafts, rain, anvil, most violent, rain vis on radar. 3) Dissipating: Down, raining itself out, leaving ice crystals in the mid & top, not very vis on radar. *4) Residue: ice crystals in the anvil, long time to evap, blocks VFR. Single-cell & Multi-cell storm TS - Answer-basic storms Single-cell: short-lived (15-30min), not violent. Multi-cell: 2 or more, each can be at dif. stages. Orographic TS - Answer-Formed when wind blows warm, humid air towards hills & Mt, if cloud forms -> could develop into TS. If stationary, flashfloods. Basic Storm (along w/ single & multi-cell). Bow-echo TS - Answer-Line of TS bent into an arc by fast wind fromt behind (rear inflow jet). Mesoscale Convective Complex - Answer-Line/region of strong TS cells w/ heavy rain followed by moderate & light rain extending over a broad region. (Mesoscale convective system TS including squall-line, bow-echo, mesoscale convective vortex). Mesoscale convective vortex - Answer-After MCC dissipates, MCV is the remaining non-stormy clouds at mid-alt w/ a slow cc-rotation. May lead to MCC from heat next day.
