Review for Atmosphere, climate and weather Dr. Makin 8th Grade Clarence Middle School
Global warming • Causes: • Burning Fossil fuels increases Carbon Dioxide in the atmosphere • Deforestation reduces the amount of CO2 absorbed by the plants
Factors that influence climate • Large bodies of water like the oceans • Large cities • Ocean currents • Trade winds
Temperature Zones • Polar zones (cold) • Temperate zones(moderate) • Tropical zones (hot and wet) • Dessert zones (hot and dry)
Factors that Cool the Earth • Pollution • Volcanic eruptions • Reflection of ice and snow
Angles of the Sun on the Earth • The lower the angle of the sun hitting a particular area on the Earth the colder that place will be.
El Nino • an irregularly occurring and complex series of climatic changes affecting the equatorial Pacific region and beyond every few years, characterized by the appearance of unusually warm, nutrient-poor water off northern Peru and Ecuador(tropical Pacific Ocean), typically in late December.
Classification of Climate • Temperature • The amount and type of precipitation • The vegetation that grow there • Climate changes less frequently unlike weather • Climate is weather measured over a long period of time
Cloud Formation • The sun warms the water on the earth and it rises to the proper altitude where it cools and condenses to form a cloud
Weather • Is measured by • Temperature • Cloud cover • Wind speed • Humidity • Air pressure • Wind direction and speed which can change with changes in temperature and pressure
Precipitation • Happens when water becomes to heavy to be suspended in the clouds.
Hurricanes • Are weather storms that can last several weeks and has winds of over 120 mph
Factors that Affect Weather • There are six main things that affect weather. These are: • Latitude • Altitude • Prevailing winds • Distance from the sea • Ocean currents • Great mountain barriers.
Fronts • A warm front is a transition zone between a mass of warm air and the colder air it is replacing. • A cold front is defined as the transition zone where a cold air mass is replacing a warmer air mass. • An occluded front is a composite front where a cold front overtakes a warm front and pushes it upward. • A stationary front is a front between warm and cold air masses that is moving very slowly or not at all.
