  1. 1. Weather and climate<br />Weather factors<br />Weather prediction<br />Climate<br />By: Beth Ginsberg<br />
  2. 2. Weather factors<br />Heat energy- a form of energy transferred by differences in temp.<br />Moisture-wet and mushy<br />Air pressure- the measure of the force with which air molecules push on a surface.<br />Winds-air moving from an area of high to low pressure<br />
  3. 3. Weather prediction<br />Weather prediction- to state what is going to happen in the atmosphere in the future.<br />Can predict:<br />Thunderstorm : cumulonimbus<br />Rain <br />Fronts : cold, warm, or stationary<br />cold : thunderstorms, heavy rain, or snow<br />Warm : drizzly rain followed by clear and warm weather<br />
  4. 4. Stationary : brings cloudy, wet weather.<br />Air masses : <br />Maritime: forms over water, wet.<br />Continental: forms over land, dry.<br />Polar : forms over polar regions, cold.<br />Tropical: forms over tropics, warm.<br />mP, mT, cT, cP<br />
  5. 5. climate<br />Climate : The average weather condition in an area over a long period.<br />Latitude: the distance north or south from the equator and is in degrees.<br />Latitude effects sunlight<br />Earth is tilted 23.5 degrees<br />Elevation-the height of an object above sea level.<br />
  6. 6. As elevation increases the ability of air to transfer energy from the ground to the atmosphere decreases<br />As elevation increases, temp. decreases.<br />Surface currents<br />Surface currents- A horizontal movement of water that is caused by wind and that occurs at or near the ocean surface.<br />When surface currents move they carry warm or cooled water to different locations.<br />
  7. 7. The surface temp. of the water affects the temp. of the air above it. <br />warm currents heat the surrounding air above it and then cause warm temp.<br />Cool currents cool the surrounding air and cause cooler temps.<br />Mountains can affect temp. and precipitation.<br />The mountain blocks the prevailing wind and affects the climate on the other side.<br />
  8. 8. The zones of climate<br />Temperate- 23.5 degrees to 66.5 degrees south<br />Tropical- 0 to 23.5 degrees south<br />Polar-66.5 to 90 degrees south<br />
