Meteorology 111 Jeopardy 1. Upper-Level Movers $200 The term that is a measure of "spin" in the atmosphere. - Vorticity $400 When you have upper-level divergence, you have what happening in the low levels. - Convergence $600 When the strongest winds in the jet stream are located upstream or to the left of the trough axis, the jet will most likely do what. - Dig $800 This type of vorticity advection leads to downward motion in the atmosphere. - NVA $1000 Daily Double - The two quadrants of a jet streak where upward motion is most favored. RRQ & LFQ 2. Low-Level Shakers $200 Converging air near the surface, causes the air to move this way. - Upward $400 This type of low-level advection causes downward motion. Cold Air Advection $600 These help to keep land masses warm in the winter, compared to other places that don‘t have these surrounding them. Lakes/Oceans/Water $800 What two processes make up Warm Air Advection (WAA) and Cold Air Advection (CAA) - Temperature and Wind. Movement of temperatures by wind. $1000 The low-level jet helps produce what type of weather in Iowa during the summer months. Nighttime Convection. 3. Temperature Toughies $200 Under what type of cloud condition (clear, scattered, or overcast) can you expect to have a warmer than usual night. Overcast $400 The thing that inhibits convection from developing a hot and humid afternoon. - Cap $600 This term for "difference in heights." It can tell you how warm or cold a layer of the atmosphere is. Thickness $800 The term that is a measure of the amount of energy in the atmosphere that is released when convection develops. CAPE $1000 This is the magic thickness number. Tell me what it is and why it’s so magical. 5400. Helps to determine roughly where the rain/snow line will be. 4. Pressure Problems $200 The basic unit of measurement for pressure in meteorology. - Millibar $400 The force that is caused by the difference in high and low pressure. Pressure Gradient Force $600 Low-level convergence is commonly associated with type of pressure. Low pressure $800 This is the pressure level, meteorologists like to use to determine where the vorticity is. 500 mb. $1000 This moves a low pressure system. Where the greatest pressure falls are ahead of the low. 5. Potpourri $200 These are warm-core systems, while your typical cyclone is cold-core. Hurricane $400 The amount of hours you subtract to go from Zulu time to Central Daylight Time. 5 $600 Visual Daily Double How strong is this wind speed? Draw 85 kts. $800 This is a term that combines the properties of temperature and dew point. It’s advection is important to cause upward motion sufficient for precipitation. - Theta-E $1000 What causes a front to move at the surface - The movement of the cold air.
