What is the general term for water vapor in the air?
humidity
Moisture, or humidity, is a general term we will use to describe the amount of water vapor in the air. There are a number of ways to express the amount of humidity in the air — the most common being absolute humidity, relative humidity and mixing ratio. We will take up each of these shortly. 02.
Which of the following words means rainy cloud?
(“Nimbus” comes from the Latin word for “rain.”) Two examples are the nimbostratus or cumulonimbus clouds.
Which forms when supercooled raindrops freeze on contact with solid objects near Earth’s surface?
Cards
| Term Cirrus | Definition high altitude clouds that are thin, wispy |
|---|---|
| Term Freezing Rain | Definition supercooled raindrops that freeze instantly when they hit a solid surface |
| Term Hail | Definition small, nearly spherical pieces of ice made by concentric layers formed by successive freezing of layers of water |
What happens when unstable air is forced to rise?
Stable air resists upward movement, whereas unstable air does not. Clouds formed when stable air is forced to rise are generally thin and precipitation, if any, is moderate or light. Conversely, when unstable air rises, clouds are often towering and precipitation can be heavy. 24.
How is water vapor created?
Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Water vapor is transparent, like most constituents of the atmosphere. Under typical atmospheric conditions, water vapor is continuously generated by evaporation and removed by condensation.
What is water Vapour short answer?
Water vapor is water in its gaseous state-instead of liquid or solid (ice). When liquid water is evaporated to form water vapor, heat is absorbed. This helps to cool the surface of the Earth. This “latent heat of condensation” is released again when the water vapor condenses to form cloud water.
What type of clouds will be seen during a stormy day?
Cumulonimbus clouds, sometimes called “thunderheads,” are associated with thunderstorms, lightning and intense, heavy rains as well as hail.
What is a wintertime form of precipitation that consists of small ice particles?
Chapters 12 & 13 & 14
| Question | Answer |
|---|---|
| A wintertime form of precipitation that consists of small ice particles is called | sleet |
| This fog forms in valleys at night | radiation fog |
| When warm moist air moves over a cold surface,____ fog may result. | advection |
| This fog results from adiabatic cooling. | upslope |
Is cloud and fog the same?
The Short Answer: Clouds and fog both form when water vapor condenses or freezes to form tiny droplets or crystals in the air, but clouds can form at many different altitudes while fog only forms near the ground.
What is a visible indicator of stable air?
Because stable air masses are, by nature, calm and free of violent disturbances, they are often marked by the appearance of stratiform clouds or fog. Stratiform clouds can be identified by their smooth, sheetlike nature and do not build vertically like clouds found in unstable air masses with convective activity.
What is the main premise behind the ice crystal Bergeron process produce precipitation?
How does the ice-crystal (Bergeron) process produce precipitation? What is the main premise behind this process? This process proposes that both ice crystals and liquid cloud droplets must co-exist in clouds at temperatures below freezing.
What kind of clouds are made of liquid water?
They are considered “mid-level” clouds and are mostly made of liquid water droplets, but can have some ice crystals in cold enough temperatures. The prefix “nimbo-” or the suffix “-nimbus” are low-level clouds that have their bases below 2,000 meters (6,500 feet) above the Earth. Clouds that produce rain and snow fall into this category.
Why do clouds appear white when it is about to rain?
Clouds usually appear white because the tiny water droplets inside them are tightly packed, reflecting most of the sunlight that hits them. White is how our eyes perceive all wavelengths of sunlight mixed together. When it’s about to rain, clouds darken because the water vapor is clumping together into raindrop s,…
What kind of precipitation does fog usually produce?
Fog commonly produces precipitation in the form of drizzle or very light snow. Drizzle occurs when the humidity of fog attains 100% and the minute cloud droplets begin to coalesce into larger droplets.
What kind of clouds produce thunder and lightning?
Thunderheads produce rain, thunder, and lightning. Many cumulonimbus clouds occur along cold fronts, where cool air is forced under warm air. They usually shrink as evening approaches, and moisture in the air evaporates. Cumulonimbus clouds gradually become stratocumulus clouds, which rarely produce rain.
