Transcript of The weather

Weather ya I wrothe the word weather but what is it? Weather is a set of all the phenomena occuring in the atmoshere at a time. Or the state of uor atmoshere By that i mean like moisture or the clouds forming or the wind. It can can also mean some natrual phenomena that efects the atmoshere like tusnami or volcanoes. BOOM So now for examples Lets start with our puffy white freinds, not mad scientist for ruining a beach day, Clouds! Hi , I'm Edward the spatula and heres a bit, or quite a bit on clouds!
High clouds:20,000-40,000 ft Cirrus clouds are long wispy clouds found high in the atmosphere.They consist of ice crystals only forming at over 26,000 feet. The clouds are very thin because moisture is sparse at high alitutudes.
These clouds cover 25% od earth's surface and has a net heating effect. They reflect 9% of sunlight and trap 50% of infrared from escaping making them part of global warming. Cirrocumulus Clouds A Solo project by Tristan Chhay These hi-altitude clouds signal convection. like other cirrus type clouds there is little water and its in a supercooled state.Instead of being wispy they are like tufts of white and gray. During the eveingthey may take in bright vibrant colors like orange, yello or red. Middle Clouds:6,500-20,000ft I'ma little fishy! How did that relate to my subject!? Altocumulus Clouds

These louds like to form globular masses or rolls in layers. They are white to light gray and often preceed a cold front. They sometime form a " mackerel sky where they form wavy dots. Destroy The
Fish! NO!!! Altostratus Clouds Classifyed by their apearance as a uniform gray sheet.The sun can shine through many layers.
They are caused by large air masses that lifts the clouds then condenses, usually on a frontal system. Low Clouds:6,500 ft and lower Stratocumulus clouds


Characherized by their large dark rolling masss very low to the ground, they don't occur above 8,000 feet.They usually bring no pecipitation, the only form is light rain or snow, but are often at the front or tail of storms indicating bad weather coming. The weekly Flash! The 7 minute newsflash! Stratus Clouds

These clouds are simular to alto straus but they maay cover the whole sky and are nearly white. They are flat, hazy and featurless. In essence they are just masses of fog. Nimbostratus Clouds

These featurless clouds are uniform dark gray. They acually form in middle cloud layer but bring percipitation and snowdown below.they often occur in or around warm fronts. They bring moderate or heavy percipitation and may cover the sky. They are commonly found in middle latitudes. Wide spread clouds: Alomst any altitude.





The original white puffy cloud,They are often asociated with fair weather. They have noticable vertical development and well defined edges. They appear alone, in lines, or in clusters. They form on warm air that rises and meets cool air condesnsing.
The moisture depends on the hight of the clouds. They do apear at differend highs but in warm arid areas they may apear at 20,600 while in cold wet areas they may be as low as 8,000 feet. They bring pleaant weather but may form cumulonimbus cluds, the classic storm cloud.
Cumulonimbus Cloud Cumulonimbus Cloud

The tall dense huge storm clouds you picure in you mind when you think of lightning although that donent always happen. They occur in cold fronts in a squall line. These clouds from from cumulus and may develop into super cells, masssive thunderstrorms. Cumulonimbus Clouds Cumulus Clouds Oh yea, one very important thing is the water cycle. natural disasters! Next focus... natural disasters are the effect of a natural hazard. They are a disaster not caused by us humans. Any event or force of nature with a cataclysmic effect. OR ANY BAD THING CAUSED BY NATURE! Some examples: Typhoons Tornadoes Hurricanes Dust storms Blizzards Tusnamis Drought MORE And more And even more AND LAVA WATER FALLS HE HE JUST KIDDING Avalanches Land slides Tropical Cyclones Tropical cyclones are swirling massive storms in the center of a convection current froming over sea. They get poweer from heat condensationa nd solar heating. The heatead air rises then cools decendinf then is caught in the heat, heats up and rises again in a loop.This is a type of convecton. Many clouds also will form near by.
Typhoons bring low pressure,Thunderstorms, instense rain and intense wind. They also caause storm surge(or rising sea.)These mean they are very destruktive.In the center some of the worlds lowest pressures where recorded.One notable storm was Tip.Sound like a lousy name for a Typhoon? well tell that to the 1,380 mile wide storm sustaining winds of 190mph.Thypoon tip is the largest storm to date. Tornadoes Hey did we do this before!?
Tornadoes are a violent,Dangerous, rotaing colom of air that conects with both the ground and a cloud(usualy cumulonimbus.)They are different from hurricanes i n the fact that they form overland and get power from spinning atmoshrere lowering towrds the ground. They are measured by the fagita scale by F-0 F-1 F-2 F-3 F-4 F-5 and thereoticaly F-6 (in an F-6 the winds would rival the speed of sound.)
Some variations of the tornado are dust devil, Fire devil and steam devils. Exuse me but we are expecting slight turbulance, Hm i wonder how this scraggly plane even took of
B L I Z Z A R D A blizzard is a severe snowstorm, characterized by strong winds. By definition, the difference between blizzard and a snowstorm is the strength of the wind. To be a blizzard, a snow storm must have winds in excess of 56 km/h (35 mph) with blowing or drifting snow which reduces visibility. Ground blizzards require high winds to stir up already fallen snow.Blizzards can bring near-whiteout conditions, and can paralyze regions for days at a time. T U N A M I I CAN SURF S Tunamis are huge waves caused by a maajor disturbancee in the sea. Earth quakes, undersea eruptions and landslides are just a few of the many triggers of this wave.Tunamis are veruy different;some may be 6.6 feet tall while others may be 303 feet tall crest to foot.They may be 120 miles wide and travel at 500mph. Avalanches The sudden rapid flow of snow down a downhill slope.They typicaly form in mountainious terrain and caryy down most everything in the path. They may be natural or man caused.Unlike other natural disasters they are not that rare and are pretty normal. when layers of snow form they accummilate in layers. different tempuretures bring different snow. When a heavy layer forms on a waek layer added pressure may cause a slide.They also occur on steep slopes L A N D S L I D E landslide or landslip is a geological phenomenon which includes a wide range of ground movement, such as rock falls, deep failure of slopes and shallow debris flows, which can occur in offshore, coastal and onshore environments. Some causes: groundwater destabilizing,erosions, loss of vegitation stabilization,earth quakes, and us. There are many different types.Debiris flows, earth flows, sturzstotms,and landslides are just a few. NO THANKS GOR WATCHING THIS USELESS PRESENTATION BY TRISTAN CHHAY! NO THANKS FOR WATCHING THIS TOTALLLY USELESS PRESENTATION! I appiciatate you watched this far, THANKS! The cycle...OHH AHH First water evaporates into vapor. Then it condenses into percipitation,rain sleet hail or snow. ThenThey flow into a lake or groundwater. If it does not go into a body of water or runoff it sinks into the ground ans ground water.
