Climate and Weather

Transcript of Climate and Weather
Precipitation Definitions of Weather and Climate... Climate is the average weather conditions for an area over a long period of time. Weather can change daily or hourly. Climate changes very slowly. Sometimes human activity, such as burning fossil fuels like coal and oil can change climate by adding chemicals like carbon dioxide to the air. This causes the atmosphere to heat up. Global Warming is caused by the Greenhouse Effect, the warming of the atmosphere as carbon dioxide and other gases trap the sun's heat in. What affects climate? Latitude: How far north or south of the equator Polar Zone: Very cold and dry. Most precipitation falls as snow. Glaciers may form. Temperate Zone: Moderate temperatures, four season Tropics: Near the equator; has most direct sunlight; very warm and usually raining Bodies of water affect climate. Being near an ocean or large lake tends to have a moderating effect on temperature and may bring more precipitation. Mountains affect climate. Higher elevations are colder. The windward side of a mountain range has more rain than the leeward side. Storms Can you name 4 kinds of precipitation? The Rain Shadow: The leeward side of mountains is dry because wet air blowing up the windward side cools and causes all the rain to fall there. The Water Cycle EVAPORATION: The sun turns liquid water in oceans and lakes into water vapor, which rises in the atmosphere. CONDENSATION: Water vapor cools and turns to a liquid water droplet on a dust particle. This forms clouds. PRECIPITATION: It rains or snows from the clouds. RUNOFF: Water goes to lakes or into the ground where it eventually runs into rivers and back into the ocean. Hail occurs as part of a thunderstorm. Hurricanes form over warm, tropical ocean water. Weather Lore Sayings used by people to help them predict the weather are called weather lore. Usually, weather lore is told in verse. Why is it usually told in verse? Indicators that actually affect the weather:
Air Pressure “When the dew is on the grass,
Rain will never come to pass.
When grass is dry at morning light,
Look for rain before the night.” “When clouds appear like rocks and towers,
The earth will be washed by frequent showers.” “A wind in the south
Has rain in her mouth.” “Expect the weather to be fair
When crows fly is pairs” INFILTRATION: Rainfall filters into the soil and becomes part of the groundwater.
