On radar displays, high reflectivity is commonly shown as which color?

• A. Blue
• B. Red
• C. Green
• D. Yellow

Answer: (B)

Radar color scales translate the amount of energy reflected by precipitation into colors that quickly convey intensity. Higher reflectivity means a stronger return, which comes from larger or more numerous hydrometeors. To make that difference obvious, display scales typically use cool colors for lower values and warm colors for higher values; red stands out as the hottest color, signaling very heavy precipitation or severe weather. So high reflectivity is commonly shown as red. Lower levels might appear blue or green, and moderate levels as yellow, with red marking the top end of the scale.
