The further we go from the equator the temperature drops and the cooler it gets PREVAILING WINDS Winds that blow from the sea often bring rain to the coast and dry weather to inland areas. Prevailing winds is the reason why temperate coastal areas often receive heavy rainfall. PREVAILING WINDS PREVAILING WINDS TOPOGRAPHY Is the relief of an area. I f an area is close to a body of water it tends to make milder climates. Mountain ranges are natural barriers to air movement. TOPOGRAPHY OCEANCURRENTS are the continuous, predictable, directional movement of seawater driven by gravity, wind (Coriolis Effect), and water density. OCEANCURRENTS  CLIMATOGRAPH A climatograph shows the monthly average temperature and precipitation for a particular area KOPPEN' S CLASSIFICATION SYSTEM TROPICALCLIMATES Tropical climates have constant high temperatures Some have up to 6 0 0 cm of rain each year Tropical Rainforest mT air masses DRYCLIMATES Dry climates cover 30 % of the Earth's land Influenced by cT air masses Scarce vegetation High Temparature,Low moisture  MILD CLIMATES Mild climates generally do not have a huge temperature difference between their cold months and warm months Winters are generally warmer Summers are generally cooler  CONTINENTALCLIMATES Continental climates are relatively dry with hot summers and cold winters Away from the bodies of water Canada  POLARCLIMATES Polar climates lie north of the continental climates known for the constant cold temperatures Has low precipitation Found near the poles and the high elevations NATURAL CAUSES OF EC  EC Earth is constantly changing, including the climate. Natural processes Human impacts  EC Ice Ages: Periods od Extensive glacial cover Ice ages have occured due to changes in Earth's tilt/ axis. VOLCANIC ERUPTIONS Volcanoes release large amounts of gas and ashes Clouds can block out the sun's radiation and cause a cooling of Earth EL NIÑO Is period where the Eastern Pacific Ocean gets warmer while the Western Pacific gets cooler Trade winds delivering warm water to the west die down The Eastern Pacific Ocean will have a pressure decreases-----> More rainfall The Western Pacific Ocean will have a pressure increases -----. Less rainfall EL NIÑO  LA NIÑA Period where the temperatures in the Eastern Pacific Ocean cool down Trade winds Strengthen blowing warm water to the west cold water piles up in the East The Eastern Pacific Ocean will have a pressure increase-----> less rainfall The Western Pacific Ocean will have a pressuredecrease-----More rainfall EL NIÑA SOLAR ACTIVITY When the sun is most active- contains sunspots (dark spots) on the sun (more solar radiation) increase in the number of the sun spots- Temperatures increase  SEASONS Seasons are short term periods of climate change Exist because Erath is tilted on its axis Some areas of the world get more direct heat from the sun. WHO WILL MAKE IT TO THE TOP? Lettheracebegin!  CHANGES IN EARTH'S ORBIT Every 1 0 0 0 0 0 years Earth's Orbit becomes more ellliptical Changes in Earth's Axis - Every41 0 0 0 years Earth's tilt changes from 22. 1 degrees to 24. 5 degrees  SEA LEVEL Sea level has flunctuated through Earth's history Global Warming activists often point rises in sea level as evidence However shifts in tectonic plates can cause a rise in a sea level  GLOBAL WARMING Increase in global temperature from an increase in Carbondioxide Might lead o the melting of the glaciers Would raise sea level 6 0 meters and would flood coastal towns GREENHOUSE EFFECT Water vapor and Carbon Dioxide- majorn greenhouse gases HUman can impact the greenhouse effect. HUman can impact the greenhouse effect. Increasing the amount of Carbon Dioxide which causes temperatures to increase beyond the normalamounts  GLOBAL WARMING Global warming could potencially have an effect on the biosphere Glaciers melt ----> Destroys polar bears habitats Sea level rises HUMAN IMPACTS ON THE ATMOSPHERE  HUMAN IMPACT (ANTHROPOGENIC) Unlike all other points in the Earth's history , many scientiest today believe that humans have the potential to alter the overall composition of the atmosphere  DEFORESTATION When trees are removed and not replanted Increase Carbon Dioxide and decreases oxygen  OZONE Ozone is a gas (O3) that exists in the Stratosphere Protects us from ultraviolet radiation Is the beginning to thin out due to the chloroflourocarbons in the atmosphere.  SMOG Smog is an atmospheric pollutant composed of an unhealthy mixture of gases caused by the reaction of sunlight with other air pollutants (CO2, NO)  ACID RAIN Acid Precipitation= Precipatation with a pH less than 7 Caused by reaction of sulfur oxides amnd nitrogen oxides with water vaper  OCEAN A CI DI FI CA TI ON Ocean acidification is the process where carbon dioxide given off by humans becomes dissolved in oceans This cause the pH tp drop and become more acidic  MICROCLIMATES Microclimates are localized climates that differ from the regional climate in which it is found Asphalt in cities stroring heat Heat Island- Temperatures in cities that are warmer than its sorrounding rural areas.  PHILIPPINES CLEAN AIR ACT OF 1999 (RA 8749) A comprehensive air quality management air quality management policy and program which aims to achieve and maintain healthy air for all Filipinos.
