Exam 7: Precipitation

Which of the following types of precipitation most likely forms when the surface air temperature is slightly below freezing and the air temperature increases with an increasing distance above the ground?

Which of the following is the most common ice crystal shape?

Which of the following conditions are necessary for falling snowflakes to survive in air with temperatures much above freezing?

Which of the following conditions are associated with large, heavy snowflakes?

Given that precipitation can be accurately measured at surface weather stations, explain why it is desirable to measure rainfall from space.

Which of the following is the name for an amount of precipitation that is less than 0.2 mm?

Which of the following is the most accurate when comparing a snow-covered surface to other natural surfaces?

Which of the following terms refers to the growth of a precipitation particle by the collision of an ice crystal (or snowflake) with a supercooled liquid droplet?

About how large can raindrops get? Why can't they get any larger? What shape does a large raindrop have? What forces determine this shape?

Which of the following is composed of a circular funnel-shaped collector attached to a long measuring tube?

Explain why the middle parts of clouds have so few ice crystals despite temperatures there that are well below freezing.

Which of the following cloud types produces precipitation by the collision-coalescence process only?

Which of the following occurs during the ice crystal process of rain formation?

Which of the following terms refers to the merging of liquid cloud droplets by collision?

Which of the following might be mistaken for hail?

Which of the following two precipitation types require a temperature inversion in the lower troposphere?

Briefly describe the differences between snow, freezing rain, ice pellets, and hail.
