What condition is necessary for Drizzle and Snow Grains to form, as mentioned in the text?
What condition is necessary for Drizzle and Snow Grains to form, as mentioned in the text?
- Drizzle and Snow Grains form from air masses with very high moisture content.
- Rain and Snow form from air masses with very low moisture content.
- Drizzle and Snow Grains form from low-lying clouds with very little vertical development.
- Drizzle and Snow grains require an overlying cold layer of air aloft to produce the precipitation, with a warmer above-freezing layer beneath. (correct)
What advantage does ground-based Weather Radar have over airborne radar, according to the text?
What advantage does ground-based Weather Radar have over airborne radar, according to the text?
- Less Backscatter, and ability to receive reflected energy back from the storm.
- Higher Reflectivity, and the ability to see smaller forms of precipitation.
- Less Attenuation, and the ability to see further into the storm. (correct)
- Higher beam width, and ability to see more of the storm per sweep.
Why are ground weather radar products considered to paint a more accurate picture of precipitation than airborne weather radar?
Why are ground weather radar products considered to paint a more accurate picture of precipitation than airborne weather radar?
- Ground weather radar is closer to the precipitation it is painting.
- Ground weather radar is more current in terms time.
- Ground weather radar is operated by individual people, rather than being automated.
- Ground weather radar products are less prone to attenuation, and is stitched together from multiple radar sites. (correct)
