Which of the following cloud types would commonly be found downwind of a mountain group of answer choices?
Wave clouds that often form over or downwind of a mountain are called: lenticular clouds.
Which cloud will have the highest base?
High-level clouds: The three main types of high clouds are cirrus, cirrostratus, and cirrocumulus. Cirrus clouds are wispy, feathery, and composed entirely of ice crystals.
What is the most common ice crystal shape?
The most common ice crystal shape is: graupel.
Why is snow challenging measured?
Why is snow challenging to measure? Snowy areas are too inaccessible to measure. Snow accumulations vary greatly from one spot to the next. It is too difficult to block wind around gauges.
What is an example of orographic clouds?
Orographic Clouds: forced by the earth’s topography. Orographic clouds are clouds that develop in response to the forced lifting of air by topographical features on the earth’s surface, like mountains for example. Air passing over a mountain will oscillate up and down as it moves downstream (see diagram below).
Which set of conditions working together will make the atmosphere more stable?
Which set of conditions, working together, will make the atmosphere the most stable? Cool the surface and Warm the air aloft.
What is the 4 types of clouds?
The Four Core Types of Clouds
- Cirro-form. The Latin word ‘cirro’ means curl of hair.
- Cumulo-form. Generally detached clouds, they look like white fluffy cotton balls.
- Strato-form. From the Latin word for ‘layer’ these clouds are usually broad and fairly wide spread appearing like a blanket.
What are 5 major types of clouds?
Ten Basic Clouds
- Cirrus (Ci), Cirrocumulus (Cc), and Cirrostratus (Cs) are high level clouds.
- Altocumulus (Ac), Altostratus (As), and Nimbostratus (Ns) are mid-level clouds They are composed primarily of water droplets.
- Cumulus (Cu), Stratocumulus (Sc), Stratus (St), and Cumulonimbus (Cb ) are low clouds composed of water droplets.
Is fog a cloud?
Fog is a kind of cloud that touches the ground. Fog forms when the air near the ground cools enough to turn its water vapor into liquid water or ice. There are many different types of fog, too. Ice fog forms when the air near the ground is cold enough to turn the water in fog into ice crystals.
What kind of crystal is formed by frozen water?
On terrestrial objects the ice crystal is the elemental unit of hoarfrost in all of its various forms. Ice crystals that form in slightly supercooled water are termed frazil. Ice originating as frozen water (e.g., hail, graupel, and lake ice ) still has hexagonal symmetry but lacks any external hexagonal form.
Why do ice crystals have different shapes?
The shapes of snowflakes are influenced by the temperature and humidity of the atmosphere. Depending on the temperature and humidity of the air where the snowflakes form, the resulting ice crystals will grow into a myriad of different shapes.
Why are ice crystals symmetrical?
The more detailed explanation is this: The ice crystals that make up snowflakes are symmetrical (or patterned) because they reflect the internal order of the crystal’s water molecules as they arrange themselves in predetermined spaces (known as “crystallization”) to form a six-sided snowflake.
Why is snow more challenging than rainfall?
It is more difficult to measure snowfall amount than rainfall amount because of the variations in the density of the snow. Density of snow greatly varies from place to place, and therefore, similar volumes of snow collected from two different places do not necessarily give the same amount of water when it melts.
What is snow measured in?
While the depth of snow is normally measured in centimetres, the measurement of melted snow (water equivalent) is in millimetres. An estimate of the snow depth can be obtained by multiplying the water equivalent by ten.
How does NOAA measure snowfall?
MEASURING SNOW Snowfall is measured to the nearest tenth of an inch. Measure the greatest amount of snowfall that has accumulated on your snowboard since the last observation. You can measure on a wooden deck or ground if a snowboard is not available. Snowfall should not be measured more than 4 times in 24 hours.
