 What is weather?

Weather is the state of the atmosphere at any time during the day or night. It includes temperature, precipitation air pressure and cloud cover. The weather changes daily due to winds and storms .

Seasonal changes are due to the Earth revolving.

Page 3: Climate  & Weather

What is climate?

Climate is an average of the weather taken on a long time period mostly 30 years on a same area of land.

In other words it is the average weather pattern for an individual region.

It describes short term state of the atmosphere.

Page 4: Climate  & Weather

Difference between climate and weather.

Climate and weather are two completely different themes. When climate is the average pattern of weather in a region, weather is the state of the atmosphere for a short period of time.

Page 5: Climate  & Weather

Climate &Atmosphere The atmosphere is a thin layer of gases

that make up what we call air. This layer helps the Earth regulate the climate it has.

The atmosphere traps green house gasses and create the green house effect.

The troposphere lets heat in Earth, but it doesn't let it out. This effect creates climate changes.

Page 6: Climate  & Weather

Climate &Atmosphere. The amount of heat trapped in the

troposphere depends on two factors. The amount of greenhouse gasses stored and the state in the atmosphere.

With out the green house effect process the earth would be a cold, lifeless planet.

It would be 18°C instead of 15°C, which is now.

Climate.Temperature, and Precipitation

Temperature: the measure of the kinetic energy level within an object, system, or body.

Precipitation: any form of liquid or solid water particles that fall from the atmosphere and reach the surface of the Earth

Page 8: Climate  & Weather

Climate.Temperature and Precipitation

Temperature and precipitation patterns that led to the Earth’s climates are mostly caused by the way the air circulates in the earths surface.

Page 9: Climate  & Weather

Temperature and Precipitation Many factors affect the way air

circulates in earths surface.▪ The amount of solar energy striking the earth in

a long term.▪ The uneven heating of the earth’s surface. ▪ Seasonal changesAs there are different ways air circulates on the

globe climate is redistributed through different places causing different temperatures and precipitations, that cause different climates.

Page 10: Climate  & Weather

Uneven heating of the Earth’s surface. The uneven heating of the surface is

simply that air is heated a lot more near the equator -were the sunrays heat directly- than in the poles –where sunlight strikes in an angle an spread toward a bigger area.

This helps explain why tropical regions are hot and vice versa.

Page 11: Climate  & Weather

Seasonal Changes

These occur because the earths axis is tilted so in the Earths normal rotation and revolving one side will receive more sunlight than the other one creating seasons.

Types of CloudsHigh Clouds 5,000-13,000m 

Noctilucent clouds are the highest clouds in the sky, however they are not associated with weather like the rest of the clouds.

Page 13: Climate  & Weather

Cirrus, Cirrostratus, Cirrocumulus Cirrus: most common  (5000-13000m) They are made entirely of

ice and consist of long wispy .Cirrus clouds are usually white and predict fair weather.

Cirrostratus: Sheet like clouds that usually cover the entire sky. The moon and stars can shine trough them. These types of clouds usually come 12-24 hours before rain or snow. 

Cirrocumulus: These clouds are shaped like small rounded puffs that usually appear in long rows.  Cirrocumulus are usually seen in winter time and they indicate fair cold weather.

Page 14: Climate  & Weather

Types of Clouds Middle Clouds.

Middle clouds are made of ice crystals and water droplets. The altitude is 2000-7000m

Page 15: Climate  & Weather

Altostratus & Altocumulus Altostratus: These type of cloud usually cover the

whole sky and has a grayish blue-ish appearance. The moon or the sun can shine through it, but it appears watery or fuzzy. Usually forms ahead of storms with continuous rain or snow.

Altocumulus: These type of clouds are grayish-white with one part of the cloud darker than the other. Altocumulus usually form in groups and are about 1 kilometer thick

Altocumulus humid morning equals thunderstorms in the noon.

Types of CloudsLow Clouds Surface-2,000m  Low clouds consist of water

droplets.

Page 17: Climate  & Weather

Nimbostratus, Stratus, Stratocumulus Nimbostratus: These clouds are dark with a ragged

These clouds mostly predict continuous rain or snow. Stratocumulus: These clouds are low, lumpy, and

gray. Only light rain generally in the form of drizzle occurs after this clouds.

Stratus: These clouds are uniform gray and cover most of the sky, it looks like a fog that doesn’t touch the Stratus clouds predict light mist or drizzle.

Page 18: Climate  & Weather

Types of CloudsClouds with Vertical Growth

Surface-13,000m These clouds grow high up into the atmosphere

instead of spreading. They can get to the troposphere and can even rise up into the stratosphere.

These type of clouds cause the most interesting weather on the Earth. 

Page 19: Climate  & Weather

Cumulus & Cumulonimbus Cumulus: These are puffy white or clear color, they look like

cotton balls. They have sharp outlines and flat base.hey are puffy white or light gray clouds that look like floating cotton balls. Cumulus clouds have sharp outlines and a flat base. Can be associated with good or bad weather.

Cumulonimbus: These clouds can grow up to 10km high. Has the top Cumulonimbus clouds are associated with heavy rain, snow, thunderstorms, hail and lightning.

Page 20: Climate  & Weather

Types of CloudsContrails 5,000-13,000m  Clouds that are formed when water vapor condenses and

freezes around small particles that come from airplanes and other machinery exhaust. The water vapor comes from the air 

Page 21: Climate  & Weather

Clouds and Climate

Clouds are important for the flow of energy that come in and out of our planet and have an great impact on Earths temperature.

Clouds have two very important influences on earth.

Page 22: Climate  & Weather

Clouds and Climate

• Clouds block sunlight form reaching the surface of earths and reflects a piece of energy that came in back to space as in a cooling way. It isnt part of the green house gasses.

• Clouds also block the energy that the earth itself emits back to space. The release of these infrared radiation is the way that the Earth gets rid of heat and when a cloud blocks it from getting it out the temperature heats up.

Page 23: Climate  & Weather

Clouds and Climate

Low clouds tend to be the good sunlight reflectors, and thus cool the planet, while high clouds tend to warm the planet by this infrared trapping mechanism.

These two processes balance each other out!

Page 24: Climate  & Weather

Clouds and Climate

While high clouds trap heat heating the earth, low clouds reflect light cooling the earth

Page 25: Climate  & Weather

Human Impact on Climate Human activities have changed the

climate by causing change in the atmosphere by creating more greenhouse gases.

Exessive greenhouse gasses affect climate by altering incoming solar radiation that comes in and out.

This creates global warming.

Page 26: Climate  & Weather

Global Warming

Refers to an average increase on the earths temperature that could change the climate resulting in ad impacts to plants, wildlife and humans.

Global warming causes climate to be unpredictable.
