Question
The size of these objects are often measured using namesake “pads” consisting of aluminum foil stretched over a piece of foam or a bucket. For 10 points each:
[10m] Name these objects that may consist of layers formed through alternating cycles of wet and dry growth. The three-body scatter spike is an artifact indicative of large instances of these objects.
ANSWER: hailstones
[10e] This type of precipitation lends its name to the central embryo of hailstones and forms when supercooled droplets land on snowflakes in a process called riming (“rhyming”). In the METAR system, hail is denoted GR, while this form of precipitation is denoted GS.
ANSWER: graupel [or corn snow, hominy snow, snow pellets, or soft hail; reject “hail” or “snow” or “pellets”]
[10h] Smaller cloud droplets decrease the riming efficiency within these clouds through aerosol indirect effects. These ubiquitous clouds are characterized by the coexistence of ice crystals with supercooled droplets.
ANSWER: mixed-phase clouds [or MPCs; accept liquid-top mixed-phase clouds or LTMPs]
