What is the purpose of dual-polarization radar technology?
- A. Increase radar range
- B. Distinguish precipitation types (rain, snow, hail, graupel) and improve QPE
- C. Reduce ground clutter
- D. Measure upper-level winds
Answer: B. Distinguish precipitation types (rain, snow, hail, graupel) and improve QPE
Dual-polarization radar transmits both horizontal and vertical pulses, allowing discrimination of hydrometeor types and improving quantitative precipitation estimates.
The moist adiabatic lapse rate (MALR) is approximately what value near the surface?
- A. 9.8°C/km
- B. 4–7°C/km
- C. 12°C/km
- D. 1°C/km
Answer: B. 4–7°C/km
The MALR varies from about 4°C/km in warm moist air to 7°C/km in cooler air, less than the DALR due to latent heat release.
Which surface feature is commonly found along the boundary between dry continental and moist Gulf of Mexico air in the US?
- A. Cold front
- B. Warm front
- C. Dryline
- D. Occluded front
Answer: C. Dryline
The dryline is a moisture boundary common over the US Great Plains, separating moist Gulf air from dry continental air.
What does divergence in the upper atmosphere typically indicate at the surface?
- A. Surface high pressure
- B. Surface low pressure and rising motion
- C. No surface weather
- D. Stable air mass
Answer: B. Surface low pressure and rising motion
Upper-level divergence removes mass from a column, lowering surface pressure and promoting rising motion.
