Atmospheric Circulation

[ORIGIN from Greek anemos ‘wind’][ORIGIN from Greek baros ‘weight’]

22.3 Atmospheric Circulation. It all starts with unequal heating of Earth that cause differences in pressure Warm air is less dense, rises and creates.

Wind – air that moves horizontally. convection cell – a pattern of rising and falling air, sinking air, and winds caused by unequal heating and cooling.

FACTS ABOUT WIND Wind is caused by air moving from high pressure to low pressure –Low: Warm air rises, less dense, humid, clouds, precipitation –High: Cold air sinks, more dense, dry, no clouds, clear sky Weather moves across the United States from west to east (prevailing winds, planetary wind belt, SW winds) Water heats up and releases heat energy slowly due to its high specific heat Land heats up and releases heat energy fast due to its low specific heat Specific Heat is the amount of energy needed to raise the temperature of a substance 1°C. Coriolis Effect is the curved path a fluid (liquid,gas) moves due to the rotation of the planet; moves clockwise, right in the northern hemisphere and counterclockwise, left in the southern hemisphere

IMPORTANT 1) Thermometer bulb must be positioned just below water surface and soil surface; Thermometer is held in place by using masking tape and attaching thermometer to cup. 2) Before experiment begins, place heat lamp bulb close to cups

TOMORROW YOU GET: You are given a blank data table to collect your data and blank graph paper to plot your data. The graph will be a double line graph (1 st line = water; 2 nd line = soil) with one axis temperature and the other axis time. You are given 20 minutes to collect your heating and cooling data for soil (land) and water. You will be given 5 minutes to discuss and set up your soil versus water experiment. We will start at Time = 0, record the temperature. Then I will start the stopwatch on the smart board and every minute I will announce the time. You will record your temperature (ºC) & time data. At 20 minutes, the experiment is over. Plot your results and start the lab write up. READY?
