Meteorology

QuestionAnswer
What are the characteristics of a CIRRUS cloud? High Clouds (20,000ft); Sometimes appear as hooked filaments called “mares’ tails”
What are the characteristics of a CIRROSTRATUS cloud? High Clouds; thin sheet of white; ice crystal clouds give sky a milky look; Produces halo around sun and moon
What are the characteristics of a CIRROCUMULUS cloud? Lowest of the high clouds with a “mackerel” look ( similar to fish scales)
What are the characteristics of a ALTOCUMULUS cloud? middle cloud 6,500-20,000ft; “sheepback” cloud; white to gray
What are the characteristics of a ALTOSTRATUS cloud? middle cloud 6,500-20,000ft; Stratified veil of clouds that produces light precipitation; When thin, sun or moon may produce a light spot, but no halos are produced.
What are the characteristics of a STRATUS cloud? Low clouds 6500ft; Low uniform layer resembling fog but not resting on the ground; May produce drizzle
What are the characteristics of a STRATOCUMULUS cloud? Low clouds 6500ft; Soft, gray clouds in globular patches or roles; Rolls may join together to make a continuous cloud
What are the characteristics of a NIMBOSTRATUS cloud? Low clouds 6500ft; Amorphous layer of dark gray clouds; One of the chief precipitation producing clouds **********
What are the characteristics of a CUMULUS cloud? Clouds of Vertical Development (Unstable); Dense, billowy often characterized by flat bases; May occur as isolated clouds or closely packed
What are the characteristics of a CUMULONIMBUS cloud? Clouds of Vertical Development (Unstable); Towering cloud, sometimes spreading out on top to form an anvil head. Associated with heavy rainfall/thunder/lightning/hail/tornadoes ************
Why are high clouds always thin in comparison to low and middle clouds? High Clouds: low temp & small quantity of water vapor makes clouds thin, white, and made primarily of ice crystals; Low & Middle Clouds: because composed primarily of water droplets, cells are more distinct
Latent Heat Situation in which it doesn’t produce a temperature change until a given point (ice in water stays the same temp until the ice is fully melted); Heat is hidden!
Heat Transfer (Water) 1 calorie (heat measurement) is needed to raise the temperature of 1 gram of water by 1 degree Celsius
Latent Heat of Melting Requires 80 calories to melt 1gram of ice
Latent Heat of Fusion When freezing, 80 calories are release for every 1gram
Adiabatic temperature changes Temperature changes in which heat was neither added or subtracted. They result when air is compressed or allowed to expand; When air is allowed to expand it cools; When air is compressed it warms; No heat is transferred in/out of a parcel (body of air)
How does Lake breeze develop? As air over land is warmed, the air expands & becomes less dense; produces a decrease in surface pressure over land; the pressure over water remains nearly constant; pressure gradient between land & water causes air over shoreline to move inland
Cold & Warm / Pressure Cold (dense) – higher pressure; Warm (less dense) – lower pressure

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
