Studying this event? See the Meteorology study guide and all practice tests.

1. Most day-to-day weather, including severe thunderstorms and tornadoes, occurs in which layer of Earth’s atmosphere, and how does temperature generally change with height in this layer?

  • A.A) Troposphere; temperature usually decreases with height
  • B.B) Troposphere; temperature usually increases with height
  • C.C) Stratosphere; temperature usually decreases with height
  • D.D) Stratosphere; temperature usually stays constant with height

2. A line of strong thunderstorms is forming along a cold front. Surface observations from three nearby towns at the same time are shown: Town 1: Temperature 29 °C, Dew point 23 °C, Light south wind, Pressure falling Town 2: Temperature 18 °C, Dew point 10 °C, Strong northwest wind, Pressure rising Town 3: Temperature 24 °C, Dew point 5 °C, Light west wind, Pressure steady At which town are severe thunderstorms most likely to DEVELOP in the next hour as the cold front moves in?

  • A.A) Town 1, because it is warm, very humid, and pressure is falling
  • B.B) Town 2, because strong northwest winds behind the front cause thunderstorms
  • C.C) Town 3, because dry air mixing with warm air always makes storms
  • D.D) All three towns are equally likely to see new severe thunderstorms

3. You see a cloud-to-ground lightning flash during a severe thunderstorm and count 18 seconds before you hear the thunder. Using the rule of thumb that sound takes about 3 seconds to travel 1 kilometer, how far away is the lightning strike?

  • A.A) About 3 km away
  • B.B) About 6 km away
  • C.C) About 9 km away
  • D.D) About 18 km away

4. A towering cumulus cloud is growing quickly on a warm, humid afternoon. The radar shows only light rain nearby, and the cloud has strong updrafts but almost no downdrafts yet. In the standard thunderstorm life cycle, which stage is this storm in?

  • A.A) Dissipating stage
  • B.B) Mature stage
  • C.C) Cumulus (developing) stage
  • D.D) Occluded stage

5. A weather radar image shows a strong line of storms. In one part of the line, there is a bow-shaped area of very high reflectivity (bright colors) bulging outward to the east. Winds at nearby surface stations shift rapidly from south to west as this feature passes. Which severe weather hazard is MOST strongly suggested by this radar feature?

  • A.A) A long-lived straight-line wind event (possible derecho)
  • B.B) A slow-moving tropical cyclone forming along the line
  • C.C) A major ice storm with widespread freezing rain
  • D.D) A lake-effect snow band setting up downwind of a warm lake

6. On a summer day, the temperature at sea level is 22 °C. An airplane climbs straight up into the troposphere to an altitude of 4 km. Assuming the average tropospheric lapse rate is 6.5 °C per km, what is the approximate air temperature around the airplane?

  • A.A) 4 °C
  • B.B) −4 °C
  • C.C) −10 °C
  • D.D) −26 °C

7. A surface weather map shows isobars packed very closely together over the central United States around a deep low-pressure center. Which condition is most likely in that region?

  • A.A) Very light winds and clear skies
  • B.B) Strong winds due to a large pressure gradient
  • C.C) Calm conditions because pressure is uniform
  • D.D) Gentle breezes caused by weak pressure differences

8. In a well-developed hurricane in the Northern Hemisphere, where are the strongest sustained winds typically found?

  • A.A) In the clear eye at the center of the storm
  • B.B) In the outermost spiral rain bands, far from the center
  • C.C) In the eyewall that surrounds the eye
  • D.D) At the very top of the storm clouds in the upper troposphere

9. A Science Olympiad team wants to investigate how updraft strength in a model thunderstorm affects the size of hailstones that form in their experiment. They use a cold room and a vertical wind tunnel with small ice pellets as “hailstones.” Which change would BEST improve their experimental design so they can clearly test the effect of updraft speed?

  • A.A) Keep temperature and humidity constant while testing several different updraft speeds
  • B.B) Change the room temperature and humidity each time they change the updraft speed
  • C.C) Use different-sized starting ice pellets for each updraft speed they test
  • D.D) Measure only how many pellets form and ignore their size to simplify the data

10. On a spring afternoon before severe thunderstorms develop, the surface temperature is 30 °C. Assuming the average tropospheric lapse rate is 6.5 °C per km and that the temperature decreases steadily with height, at approximately what altitude will the air temperature drop to 0 °C (the freezing level)?

  • A.A) 2.0 km
  • B.B) 3.0 km
  • C.C) 4.5 km
  • D.D) 6.0 km
