This PowerPoint explains how convection affects weather patterns and climate.Students must know that because warm air near Earth’s surface rises and then cools as it goes up, a convection current is set up in the atmosphere. There are three atmospheric convection areas in the northern hemisphere and three in the southern hemisphere: arctic region, temperate region and tropical region. Students will learn the wind belts located in that region: polar winds, trade winds and westerlies. Colorful graphics and easy to read! ALSO includes simulation from NOAA website to show land and sea breezes during a 24 hour period. Powerpoint also includes information about the ocean currents that affect weather and climate --> California and Gulf Stream Current! Guided notes to be used during lesson are included in store titled "Global and Local Convection Notes Guide".
