THE ATMOSPHERE

When you look up outside what you see is the long beautiful sky. What you arelooking at is the atmosphere. The atmosphere is like a multi flavored cake, it

holds different layers. Above the surface of Earth (where we live) is the lowest layer called the Troposphere. Above that is the next layer, Stratosphere. Continuing

that layer is the Mesosphere and on the very top is the Thermosphere.

Convection

Convection is the moving of molecules in a liquid by heating it. Pretend the liquid is

the cold mug of hot chocolate and there are millions of teeny tiny marshmallowssitting still inside. When you put the mug in the microwave to heat it the liquid

turns hotter and the marshmallows inside begin to move. This is called convection.Convection occurs in weather when there are drops and rises in cold and warm

wind.

WIND CURRENTS

A wind current is a large blow of wind that is registered as a type. These types are the

Westerlies – winds that blow on the latitude lines (lines that have degrees and flow horizontally on maps and globes.)

Trade winds – surface winds found near the lower section of the troposphere

Equatorial winds – wind patterns that happen across the earth's equatorPolar easterlies - dry, cold winds that spread and flow from the high

pressure areas of the north and south pole

OCEAN CURRENTS

Density Currents- is a warm current(wave type length) that floats on a cooler current

Surface Currents- Make up 10% of oceans water. 1st 400 ft of ocean water are surface currents.

Deep Water Currents- Makes up the other 90% and these waters are salty and cold and sink back into deep ocean.

Northern Hemisphere Currents- are the ocean currents pushed by winds northern

HIGH PRESSURES

High pressure basically makes good weather. It creates clear skies, sometimes cool air, and no precipitation. Sometimes it can create clouds. High pressure is created because of the Earth being heated unevenly.

LOW PRESSURES

Low pressure is the term used to describe an area of air pressure that has a lower concentration than the area surrounding it. It holds warm air, high winds, precipitation and clouded storms.

Fronts

A front is basically a boundary between two large air masses with very different air masses. There are usually two known types of fronts; warm fronts and cold fronts. Cold fronts usually bring cold weather, precipitation, and winds. Warm fronts bring warm weather, humidity, and clear skies. Two more types are stationary fronts, and Occuled fronts.

HURRICANES

Hurricanes are formed when cold air from the ocean and warm air from land collapse together at a point, mixing in a spiral motion. Then these storms move to land, bringing thunder, lightning, and high winds that can cause enormous amounts of damage.

TORNADOS

Tornadoes occur when cumbulonimbus clouds touch the Earth's surface and create a rapid fast spinning and destructive column of of air that destroys everything in it's path until it subsides and fades away.

The Sun's Energy

Without the sun there would be no life. The sun is the biggest and the most relied upon source of heat for all the earth. Every living creature on this planet relies on the sun for its energy. All energy on earth comes from the sun. The sun's energy causes all of the different pressures which then creates different winds, therefore creating different ocean currents.

WEATHER MAPS

ISOTHERM AND ISOBAR

When you look at a globe or a map and see two points that are the same numeral this is called Isotherm. The two points that are the same.

Isobar is the line that connects two points that are alike or have the same pressure.

TYPES OF PRECIPITATION

Types of precipitation include:Rain- water that falls from condensed cloudsSnow- frozen water that falls like powderSleet- basically the same as snow, but more solid/wateryHail- frozen pellets of ice that fall from condensed clouds

TYPES OF CLOUDS

There are three types of clouds-~Cirrus~Stratus~Cumulus

-Cirrus clouds are very long, string, and close to the ground.

-Stratus clouds are long, gray, and high up in the sky. -Cumulus clouds are white, bunched up, and they look likefloating cotton balls.

DEW POINT

Dew Point is the point where the humidity drops while evaporation and the water condenses into tiny droplets of water.

HOW SCIENTISTS GET IMAGES

Scientists get images of different patterns of weather mainly by satellites. Satellite imagery is used to provide a large-scale picture of an area. They can see activity in places over large scales, like storms or clouds. They also can use a weather balloon, which floats up and brings back atmospherical information.

METEOROLOGICAL INSTRUMENTS

Meteorological Instruments are used to identify different weather patterns for different types of weather. for example, a barometer is used to measure air pressure. A Weather Balloon is used to bring back atmospherical information. A Thermometer is used to tell the temperature of water or air. A compass can be used to tell direction of oncoming storms and winds. A speedometer will show the wind speed.
