Within a developing cumulonimbus (thunderstorm) cloud, the ascending cloudy air [(cools) (warms)] at an average rate of [(12.0) (9.8) (6.0)] Celsius degrees per 1000 m. If the temperature of the updraft at the convective condensation level (altitude of 2000 m) is 5 °C (41 °F), predict the temperature of the updraft near the top of the cloud (altitude of 12,000 m). Answer: _____ °C. Based on this temperature, upper reaches of the cloud are likely composed of [(water droplets) (supercooled water droplets) (ice crystals)] exclusively.
