Weather and climate

1. Weather and climate Rafaela Diaz 8E

2. Difference between weather and climate • The difference between weather and climate is a measure of time. • Weather is what conditions of the atmosphere are over a short period of time. • Climate is how the atmosphere "behaves" over long periods of time. • An earlier springtime is indicative of a possible change in the climate.

3. How atmosphere, temperatureand precipitation affect climate • Atmosphere: • The greenhouse effect. • They allow light, infrared radiation, and some ultraviolet radiation from the sun to pass through the troposphere. • This gases warm air and heat up our climate • Temperature: • Depending on the variation of temperature, climate is affected. • Hotter of colder. • If temperature is hotter-evaporation of water, oceans, dryness, warm climate. • If temperature is cold-frizzing of lakes, oceans, snow, cold climate. • Precipitation: • Water evaporates because of the excessive heat of weather and then it turns into water in clouds and then it become rainfall. • Rainfall affect climate by producing humidity and heat in some places like the coast and by producing freezing temperatures in zones like the mountains.

4. CLOUDS • A cloud is a large collection of tiny drops of water or ice crystals. The drops are so small and light that they can float in the air. • Clouds Types:

5. CLOUDS • CIRRUS CLOUDS • Cirrus: These clouds are composed of ice and are thin, soft clouds blown in high winds into long streamers. They are usually are whiter than others. • Cirrostratus: These clouds are very thin and frequently they cover the entire sky. Cirrostratus clouds usually come 12 to 24 hours before a rain or snow storm. • Cirrocumulus: These clouds are small, circular white puffs that are in rows in the sky. They appear mostly in the winter and cold weather. • ALTO CLOUDS • Altostratus: These clouds are gray mid level clouds composed of ice crystals and water drops. Altostratus clouds often form ahead of storms with continuous rain or snow.Altocumulus: These clouds are made of water drops and appear as gray puffy clouds. They are formed in groups.

6. clouds • How clouds affect weather? • They carry water that falls to the earth's surface as rain and snow to then support all forms of life. • Clouds can sometimes bring destruction in the form of hail or tornadoes. • How clouds affect climate? • Clouds reflect one part of the sunlight to the space, so less solar energy reaches the ground. • When a cloud absorbs radiation emitted by the Earth's surface, the cloud reemits a portion of the energy to outer space and a portion back toward the surface, thus warming our planet . • The less clouds in the atmosphere, the more the surface is heated.During the night, if there is no clouds the night is colder because most of the infrared radiations emitted by the Earth are send back to the space. • Low, fluffy clouds keep us cooler. • Clouds reflect sunlight, so that make like a shadow in a sunny day.

7. CLOUDS • STRATUS CLOUDS • Stratus clouds: These clouds are uniform grayish clouds that frequently cover the entire sky. They resemble mist that doesn't reach the ground. Stratocumulus: These clouds are low, puffy and gray. Mostly they form in rows with blue sky visible in between them. They can transform into nimbostratus clouds.Nimbostratus: These clouds form a dark gray cloudy layer with continuously falling rain or snow.

8. clouds • CUMULUS CLOUDS • Cumulus clouds: These are white and puffy clouds. The base of these cloud is flat and the top of each cloud has rounded towers. Cumulus clouds grow and they can transform into giant cumulonimbus clouds, thunderstorm clouds. • Cumulonimbus: These are thunderstorm clouds. Cumulonimbus clouds are connected with heavy rain, snow, hail, lightning and even tornadoes.

9. clouds • Special Clouds • Mammatus: Mammatus clouds are usually associated with severe weather.Lenticular: These clouds are caused by a wave wind pattern created by mountains. They have a disk-like shape that from near mountains. Fog: This cloud is composed of billions of tiny water drops floating in the air. It is on the ground.Contrails: These are condensation trails left behind jet aircraft.Green Clouds: They are often associated with severe weather. They have green color that is not completely understood, but it is thought to have something to do with having a high amount of liquid water drops and hail inside the clouds.

10. Human activities • Human Technology.- Contamination/ Deforestation • Contamination and Deforestation have cause a great impact on atmosphere and climate. • Contamination chemicals is harming the ozone layer, and making a big hole and this produce that the sun rays penetrate to our planet warming it up. • Global Warming.-build up greenhouse gases in the atmosphere due to human activities as fossil-fuel burning and destruction of forests.
