What temperature range is typically associated with rime icing?

• A. -5 to -10 C
• B. -10 to -20 C
• C. -20 to -30 C
• D. 0 to -5 C

Answer: (B)

Rime icing typically occurs in temperatures ranging from approximately -10 to -20 degrees Celsius. This phenomenon arises when supercooled water droplets collide with an object, such as an aircraft wing or tree branches, freezing upon contact. The temperature range is crucial because at these colder temperatures, the water droplets remain in a supercooled state for a longer period, allowing for the accumulation of rime ice. In contrast, at temperatures above -5 degrees Celsius, ice formation is less likely due to the higher temperatures leading to more rapid melting of any ice that begins to form. At temperatures below -20 degrees Celsius, the conditions shift increasingly towards another type of icing known as clear ice, which forms differently. Therefore, the temperature range of -10 to -20 degrees Celsius is specifically conducive to the formation of rime icing, making this the correct answer.
