Just a video about clouds for school.

1. THE DIFFERENCES IN CLOUDS
BY: TRISTEN WALENDZAK

2. WHAT IS A CLOUD?
• MASS OF WATER IN SKY: A VISIBLE MASS OF WATER OR ICE PARTICLES IN THE ATMOSPHERE
FROM WHICH RAIN AND OTHER FORMS OF PRECIPITATION FALL
• MASS OF PARTICLES IN AIR: A MASS OF PARTICLES IN THE AIR, E.G. DUST OR SMOKE

3. HOW MANY DIFFERENT TYPES OF CLOUDS ARE
THERE?
• THE FOUNDATION CONSISTS OF 10 MAJOR
CLOUD TYPES. IN ADDITION TO
CIRRUS, STRATUS, CUMULUS, AND NIMBUS
CLOUDS, THERE ARE
CIRROSTRATUS, CIRROCUMULUS, ALTOSTRAT
US, ALTOCUMULUS, STRATOCUMULUS, NIMB
OSTRATUS, AND CUMULONIMBUS CLOUDS.

4. WHAT IS A CIRRUS CLOUD?
• A GENUS OF ATMOSPHERIC CLOUD GENERALLY
CHARACTERIZED BY THIN, WISPY STRANDS, GIVING THE
TYPE ITS NAME FROM THE LATIN WORD CIRRUS MEANING
A RINGLET OR CURLING LOCK OF HAIR.
• CIRRUS GENERALLY APPEARS WHITE OR LIGHT GRAY IN
COLOR. IT FORMS WHEN WATER VAPOR UNDERGOES
DEPOSITION AT ALTITUDES ABOVE 5,000 M (16,500 FT) IN
TEMPERATE REGIONS AND ABOVE 6,100 M (20,000 FT) IN
TROPICAL REGIONS. IT ALSO FORMS FROM THE
OUTFLOW OF TROPICAL CYCLONES OR THE ANVILS OF
CUMULONIMBUS CLOUD.

5. WHAT IS A STRATUS CLOUD?
• A CLOUD BELONGING TO A CLASS CHARACTERIZED BY
HORIZONTAL LAYERING WITH A UNIFORM BASE, AS
OPPOSED TO CONVECTIVE CLOUDS THAT ARE FORMED BY
RISING THERMALS (THESE ARE ALSO KNOWN AS
CUMULIFORM CLOUDS). MORE SPECIFICALLY, THE TERM
STRATUS IS USED TO DESCRIBE FLAT, HAZY, FEATURELESS
CLOUDS OF LOW ALTITUDE VARYING IN COLOR FROM
DARK GRAY TO NEARLY WHITE. STRATUS CLOUDS MAY
PRODUCE A LIGHT DRIZZLE OR SNOW.

6. WHAT IS A CUMULUS CLOUD?
• A GENUS-TYPE OF LOW-LEVEL CLOUD THAT CAN
HAVE NOTICEABLE VERTICAL DEVELOPMENT AND
CLEARLY DEFINED EDGES. CUMULO- MEANS "HEAP" OR
"PILE" IN LATIN.
• THEY ARE OFTEN DESCRIBED AS "PUFFY" OR "COTTONLIKE" IN APPEARANCE, AND GENERALLY HAVE FLAT
BASES.

7. WHAT IS A NIMBUS CLOUD?
• A CLOUD THAT PRODUCES PRECIPITATION. USUALLY THE
PRECIPITATION REACHES THE GROUND AS
RAIN, HAIL, SNOW, OR SLEET.
• NIMBUS CLOUDS ARE FORMED AT LOW ALTITUDES AND ARE
TYPICALLY SPREAD UNIFORMLY ACROSS THE SKY.

8. CIRROSTRATUS
• A HIGH, THIN, GENERALLY UNIFORM
STRATIFORM GENUS-TYPE, COMPOSED OF
ICE-CRYSTALS. IT IS DIFFICULT TO DETECT
AND IS CAPABLE OF FORMING HALOS
WHEN THE CLOUD TAKES THE FORM OF
THIN CIRROSTRATUS NEBULOSUS.
CIRROCUMULUS
• ONE OF THE THREE MAIN GENUS-TYPES OF
HIGH-ALTITUDE TROPOSPHERIC
CLOUDS, WHICH ALSO INCLUDES CIRRUS
AND CIRROSTRATUS.[3] THEY USUALLY
OCCUR AT AN ALTITUDE OF 5 KILOMETRES
(16,000 FT) TO 12 KILOMETRES (39,000 FT).

9. ALTOSTRATUS
• A MIDDLE ALTITUDE CLOUD GENUS
BELONGING TO THE STRATIFORM PHYSICAL
CATEGORY CHARACTERIZED BY A
GENERALLY UNIFORM GRAY TO BLUISHGRAY[3] SHEET OR LAYER, LIGHTER IN
COLOR THAN NIMBOSTRATUS AND DARKER
THAN HIGH CIRROSTRATUS. THE SUN CAN
BE SEEN THROUGH THIN ALTOSTRATUS, BUT
THICKER LAYERS CAN BE QUITE OPAQUE.

10. ALTOCUMULUS
• A MIDDLE ALTITUDE CLOUD GENUS THAT BELONGS
TO THE STRATOCUMULIFORM PHYSICAL CATEGORY
CHARACTERIZED BY GLOBULAR MASSES OR ROLLS
IN LAYERS OR PATCHES, THE INDIVIDUAL ELEMENTS
BEING LARGER AND DARKER THAN THOSE OF
CIRROCUMULUS AND SMALLER THAN THOSE OF
STRATOCUMULUS. LIKE OTHER CUMULIFORM AND
STRATOCUMULIFORM CLOUDS, ALTOCUMULUS
SIGNIFIES CONVECTION. IT IS USUALLY WHITE OR
GREY, AND OFTEN OCCURS IN SHEETS OR PATCHES
WITH WAVY, ROUNDED MASSES OR ROLLS.

11. STRATOCUMULUS
• A GENUS-TYPE OF CLOUDS CHARACTERIZED
BY LARGE DARK, ROUNDED MASSES, USUALLY
IN GROUPS, LINES, OR WAVES, THE INDIVIDUAL
ELEMENTS BEING LARGER THAN THOSE IN
ALTOCUMULUS, AND THE WHOLE BEING AT A
LOWER ALTITUDE, USUALLY BELOW 2,400 M
(8,000 FT). WEAK CONVECTIVE CURRENTS
CREATE SHALLOW CLOUD LAYERS BECAUSE OF
DRIER, STABLE AIR ABOVE PREVENTING
CONTINUED VERTICAL DEVELOPMENT.

12. NIMBOSTRATUS
• CHARACTERIZED BY A FORMLESS CLOUD LAYER
THAT IS ALMOST UNIFORMLY DARK GREY. "NIMBO"
IS FROM THE LATIN WORD "NIMBUS", WHICH
DENOTES PRECIPITATION. IT IS GENERALLY A
STRATIFORM CLOUD OF MODERATE VERTICAL
DEVELOPMENT (FAMILY D1) THAT PRODUCES
PRECIPITATION, DEVELOPING CLOUD BASES
BETWEEN THE SURFACE AND ABOUT 10000 FT
(3000 M). THIS CLOUD TYPICALLY FORMS FROM
ALTOSTRATUS IN THE MIDDLE ALTITUDE RANGE THEN
SUBSIDES INTO THE LOW ALTITUDE RANGE DURING
PRECIPITATION.

13. CUMULONIMBUS
• A DENSE TOWERING VERTICAL CLOUD
ASSOCIATED WITH THUNDERSTORMS AND
ATMOSPHERIC INSTABILITY, FORMING FROM
WATER VAPOR CARRIED BY POWERFUL
UPWARD AIR CURRENTS. CUMULONIMBUS
MAY FORM ALONE, IN CLUSTERS, OR ALONG
COLD FRONT SQUALL LINES. THEY ARE
CAPABLE OF PRODUCING LIGHTNING AND
OTHER DANGEROUS SEVERE WEATHER, SUCH
AS GUSTS, HAIL, AND OCCASIONAL
TORNADOES.

14. • OVER ALL WE LEARNED ABOUT THE TEN
DIFFERENT CLOUD TYPES AND OUT OF
ALL OF THEM WHICH ONES CREATE
SNOW, ICES, RAIN, AND HAIL. I HOPE
YOU ENJOYED THIS PRESENTATION AND
HOPEFULLY LEFT HERE LEARNING
SOMETHING NEW. 
