Every time planet Earth has gone from a glacial to an interglacial period, this jump in temperature correlates roughly with changes from ______ to _______ levels of carbon dioxide. Those who believe global warming is going on point to increases in temperatures in the 20th century, while skeptics point that this increase simply correlates with Earth naturally rebounding from a ________ in the preceding centuries. What might be some of the effects if global warming takes place? What might explain late 20th century temperature increases besides global warming?

Arctic Circle Tropic of Cancer Equator Tropic of Capricorn Antarctic Circle Can you identify the correct order of latitudinal zones from Equatorial to Polar? Siberia Where would EXPECT to see the greatest annual temperature variation? Why is it colder in Siberia in winter than at the North Pole? Why would land heat up to higher temperatures than an adjacent area of water? it is a continental location, the north pole is a maritime location the ocean takes longer to heat up and to cool down Ocean/coast climate, less temperature range because water takes longer to heat and cool Continental climate, more temperature range because land heats and cools much faster than water Possible Answers Just before the sun comes up (5am6am) What does a "maritime" climate mean? What does a "continental" climate mean? Where would you go to swim in warm water, the west or the east coast of the United States? Why? The east coast ocean currents are warm How do cold currents influence isotherms? In the middle of North America, isotherms bend towards the equator in winter and they bend towards the pole in summer. Why do they do this? Geographers make maps of: elevation temperature pressure precipitation using isotherms isohyets isobars contour lines Match these lists.

Why does the pressure gradient "win" close to Earth's surface, such that winds spiral into low pressure cells? Winds flow parallel to isobars in the upper atmosphere?? The coriolis effect has a much less impact on winds closest to the surface, especially around the equator. Cyclonic = winds flow counterclockwise around the center; winds spiral upward and inward; usually cloudy with possible precipitation Anticyclonic = winds flow counterclockwise around the center; winds spiral down and outward; usually clear skies with no precipitation India/Indian Ocean What does cylclonic mean?

How do tiny drops of water grow big enough and heavy enough to fall out of a cloud and reach the ground as rainfall? Why does advection fog occur along the west coasts of continents? saturation quantity by lowering the temperature Turn on the heat because warm air holds more moisture Soda cools the air around it until the dew point is reached Tiny water droplets Water condenses around the dirt - cloud condensation nuclei Condense together and are heavy enough to overcome wind resistance and updrafts There is a cold current that chills air until the dew point is reached. When it's reached condensation occurs. Clear skies, little wind, lots of moisture close to the ground What conditions promote the formation of radiation fog? Longwave radiation leaves during the Why does radiation fog start to form early in the morning, but advection night, so air by the ground is chilled by the fog can "roll in" just about anytime. ground. Water is always cold and just need winds to move over cold ocean current. What is the difference between orographic clouds and valley fog? Valley fog happens when the air is chilled in the valley.

If it is unstable, it will __________. Which of these conditions would lead to the development of thunderstorms? Possible Answers If it is stable, it willfall and drop back down producing no thunderstorms. If it is unstable, the air keeps rising until lifting condensation level and forms clouds Unstable leads to thunderstorms. More pressure. Why does a parcel of air heat when pushed down in the atmosphere and cool when pushed up in the atmosphere? Match the lapse rate with the following information: Dry Adiabatic Wet Adiabatic Environmental 10C/1000m 3-6C/1000m relative humidity < 100% relative humity = 100% release of latent heat the real temperature of the atmosphere Why does temperature change between dry and wet lapse rate? During the dry lapse rate, air is not condensing. During the wet, air is condensing. As condensation begins, latent heat is released. Dry Wet Wet When a parcel of air is lifted, it cools at the dry adiabatic lapse rate until The heat released from condensation the dew point is reached and it now cools at the wet adiabatic lapse rate. causes the lapse rate to decrease (to the wet Why does the lapse rate change? rate) You are given a simple adiabatic chart of elevation versus temperature with the dry, wet, and environmental lapse rates drawn. Can you say whether this chart represents a "stable" or "unstable" atmosphere. In winter, on the eastern side of the Rocky Mountains, the cold air moving south from Canada is a _______ air mass. Sometimes, wind directions shift to bring air from the west. For people living next to mountains, this brings lee or Chinook winds. Why does the air get much warmer when the Chinook winds come? Why is the air warmer and drier on the lee side of a mountain range? What is the cause of rainshadows? Compare the location of rainshadows in the belt of the westerly winds and trade winds. On what side would you go to be in the rainshadow? In an inversion, air temperature __________ with elevation. Why is this condition called an inversion? Would you expect to find warmer air or colder air at the surface, when an inversion occurs? Why do inversions trap pollution? Why does the presence of mountains make the pollution worse? decreases it is an inverse of the normal temperature with elevation There is little vertical mixing Yes, to the people on either side of them. The pollution has even less room to mix because the mountains block the escape route. Adiabatic warming- descending air, temp increases, and the relative humidity decreases, the air dries out .

Can you match: cold front warm front occluded front with: symbols on a weather map cross-sectional diagram Why is a mid-latitude cyclone called a "wave" cyclone? What happens to pressure, wind direction, temperature, and precipitation as an "open" mid-latitude wave cyclone passes over you? In other words, what is the weather that will happen before a warm front, as the warm front gets to you, after the warmfront/before the coldfront, as the cold front gets to you, and after the cold front Why doesn't California and Arizona experience the warm front part of mid-latitude wave cyclones? What three factors are needed to have Arizona experience mid-latitude wave cyclones? What "fuels" mid-latitude wave cyclones? [Hint: it is the same process the "fuels" hurricanes.] . Tropical Hurricanes Questions What "fuels" hurricanes? What are the conditions of the ocean and atmosphere that will allow hurricanes to grow?

What are the most damaging effects of hurricanes? What aspect of a hurricane encourages a storm surge? Study Guide Questions: rainfall and flooding tornadoes storm surges high winds mass wasting Low pressure rises the seal level. Use these questions to prepare for the test. One of the best ways to learn how to take multiple choice tests is to write distracters (one close answer, one answer that can detect if student mixes concepts, one answer farther away). Thus, I've put this in table form, to encourage you to think about how you would write the distracters. .World Climates Can you match these climates: rainforest savanna subtropical desert steppe mediterranean marine west coast humid subtropical humid continental boreal tundra ice sheet with their climographs the processes that bring rain or dry conditions Water Balance and Climate Change Questions Possible Answers The combination of water released to the atmosphere by evaporation and transpiration.
