  1. Physical Geography Climate & LACEMOPS

  2. FACTORS THAT AFFECT CLIMATE http://upload.wikimedia.org/wikipedia/commons/thumb/9/97/The_Earth_seen_from_Apollo_17.jpg/300px-The_Earth_seen_from_Apollo_17.jpg LACEMOPS

  3. Weather – The daily condition of the atmosphere which includes temperature & precipitation Precipitation - Moisture that falls from the sky 4 forms: rain, snow, sleet, & hail Climate - Average weather-over an extended period of time (usually 30 years) http://www.mnh.si.edu/archives/garden/images/4seasons.gif

  4. L - LATITUDE - The most important factor! The farther from the Equator - the colder & drierit becomes. Direct rays of the sun are always between the Tropics. Areas not in the tropics receive indirect sun rays. High Mid Low High

  5. A - AIR MASSES Northern Hemisphere,cold air from the Polar Regions comes from the north Hot air from the tropics comes from the south Mountains to the north of a city could block the cold air from reaching the city (Opposite in the Southern Hemisphere)

  6. C - CONTINENTALITY Water moderates climate. Water takes longer to heat and cool than land. Areas inland from the coast will be hotter in the summer and colder in the winter than areas with the same latitude on the coast http://images.google.com/imgres?imgurl=http://edc.usgs.gov/imagegallery/imageSrc/United%2520States-NED500.jpg&imgrefurl=http://edc.usgs.gov/imagegallery/imageDetail.php%3Fpage%3D18%26img%3DUnited%2BStates-NED%26id%3D2071%26col%3DStates%2B-%2BNED%2BShaded%2BRelief&h=353&w=500&sz=121&hl=en&start=17&um=1&tbnid=tsJBVC5mQRiZ6M:&tbnh=92&tbnw=130&prev=/images%3Fq%3Dunited%2Bstates%2B%26svnum%3D10%26um%3D1%26hl%3Den%26safe%3Dactive%26rls%3Dcom.microsoft:en-us:IE-SearchBox%26rlz%3D1I7GGLG%26sa%3DG

  7. E - ELEVATION It gets colder as you go up a mountain. The formula for vertical climate is: Temperature decreases 3.5º F for every 1,000 feet increase in elevation (the opposite is also true). You can work out the temperature at the top of a tall mountain. http://images.google.com/imgres?imgurl=http://www.savetibet.org/images/images/MountEverest.jpg&imgrefurl=http://www.savetibet.org/news/newsitem.php%3Fid%3D1050&h=300&w=400&sz=22&hl=en&start=6&um=1&tbnid=ODjU-A29uyNbXM:&tbnh=93&tbnw=124&prev=/images%3Fq%3Dmt%2Beverest%26svnum%3D10%26um%3D1%26hl%3Den%26safe%3Dactive%26rls%3DGGLG,GGLG:2005-42,GGLG:en http://www.commondreams.org/headlines05/images/0314-01.jpg

  8. It is 75º at the base of a 15,000 ft. tall mountain. What is the temperature on top of the mountain? First, count the thousands… (15,000) Second, multiply that number by 3.5… 3.5° (from formula) X 15 (how many thousands of feet the mountain is tall) 52.5° (how much colder at the top than the bottom) Third, Subtract that number from the temperature at the base to get the answer… 75° (temperature at bottom) - 52.5° (how much colder at the top) 22.5 ° (temperature at the top)  Answer

  9. M - MOUNTAIN BARRIERS Orographic effect: Wind containing moisture hits the windwardside of a mountain (facing the wind) Moisture-full clouds are too heavy to get over the mountain so precipitation occurs, after they’re empty, they are able to rise over the mountain. The side facing away from the wind-leeward side. The windward side -lush vegetation The leeward side-usually a desert

  10. O - OCEAN CURRENTS Cold currents bring dry, cool air to the coastal areas. Warm currents bring warm, wet air to coastal areas. http://go.owu.edu/~jbkrygie/krygier_html/geog_111/geog_111_lo/geog_111_lo05_gr/3-16.jpg

  11. P - PRESSURE AND PREVAILING WINDS: Pressure High pressure is heavy, cold air. Low pressure is warm, light air. Heat rises. There are some fairly constant air pressure systems. Notice that these lines are located at 0, 30, 60, 90 (not 0, 23 ½, 66 ½, and 90)

  12. Prevailing Winds The Equator is surrounded by an area of calm called the Doldrums (ITCZ). The Trade Winds (Tropical Easterlies) blow from east to west (warm & moist). Westerlies(Prevailing Westerlies)blow from west to east. The PolarEasterlies blow from 90ºin an eastward direction toward the Westerlies. There are serious thunderstorms around 60ºlatitude where the 2 wind patterns collide http://www.worldstats.org/general_world/maps/prevailing_winds_big.gif Notice that these lines are located at 0, 30, 60, 90 (not 0, 23 ½, 66 ½, and 90)

  13. S - STORMS Where the Polar Easterlies meet the Westerlies there are thunderstorms. When hot air masses and cold air masses collide - there are storms. Cyclonic storms (hurricanes, typhoons, etc.) in the Northern Hemisphere spin counter-clockwise In the Southern Hemisphere cyclones spin clockwise.
