In the atmosphere, cloud condensation nuclei are abundant than ice-
forming nuclei. - ANSWER: More
Where there is an abundance of hygroscopic nuclei in the atmosphere, clouds are
likely to develop at relative humidities 100%. - ANSWER: Under
If cumulus clouds (puffy clouds that build vertically) continue to develop to great
altitudes, the atmosphere is - ANSWER: Unstable
Lee-wave clouds form of a mountain range. - ANSWER: Downwind
Overnight radiational cooling of clear air may cause temperatures to reach
saturation with stable conditions to form fog. - ANSWER: Radiation
The water droplets and ice crystals that make up clouds are always falling relative
to the air, yet the clouds themselves may not be falling relative to the Earth's
surface. This happens because clouds are most likely to be located where
prevail. - ANSWER: Updrafts

Water in solid or liquid form that falls from clouds to the Earth's surface is known
as - ANSWER: Precipitation
Which one of the following particles has the greatest terminal velocity in still air? -
ANSWER: Rain drop
Cloud droplets can cool to temperatures well below 0 °C (32 °F) without freezing.
When these so-called supercooled droplets coexist with ice crystals in the same
cloud, the grow in size. This is the basis of the Bergeron-Findeisen process
that is responsible for the formation of most precipitation. - ANSWER: Ice
crystals
At least some of the water (in the liquid or solid form) falling from a cloud
vaporizes as it passes through air below the cloud base. If the water
completely vaporizes before reaching the Earth's surface, the shaft of falling liquid
or ice particles is known as virga. - ANSWER: Unsaturated
Freezing rain (or drizzle) occurs when falling water drops are ; thus, drops
partially freeze when they strike cold surfaces. - ANSWER: Supercooled
Acid rain (or snow) occurs when the pH of the precipitation is less than -
ANSWER: 5.6

For a weather radar operating in the reflectivity mode, the strongest echoes are
produced by - ANSWER: Hail
As a general rule-of-thumb, on average, 13 inches of snow will melt down to 1
inch of liquid water. Therefore, a 33-inch snowfall will produce approximately
inches of liquid. - ANSWER: 2.5
Remote sensing of precipitation amounts over the vast areas of tropical oceans is
possible with data from the satellite. - ANSWER: GPM
A mass of cold, dry air is a mass of warm, humid air. Consequently,
warmer (lighter) air is often forced to rise above the sloping frontal surface
overlying colder (denser) air. - ANSWER: Denser than
Ascending unsaturated (clear) air , cooling at about 10 Celsius degrees
per 1000 meters of ascent (5.5 Fahrenheit degrees per 1000 feet). - ANSWER:
Expands
The warmer air rising above the frontal surface expands and cools as it ascends,
and its relative humidity . If saturation is achieved, clouds develop and
from those clouds, rain or snow may fall. - ANSWER: Increases
