2. SOL REVIEW….Weather and Atmosphere Read each fact carefully and then be prepared to answer the questions that follow NO TALKING Highlight what you do not remember!! HERE WE GO

3. WEATHER Weather describes the day-to-day changes in atmospheric conditions Climate describes the weather patterns for a given location over a period of years. Winds are created by the uneven heating of the earth’s surface (remember we’re tilted on our axis…23.5°) Winds blow from a high to a low Convection currents …hot air rises and cold air sinks… is a major cause of weather Major climate zones are polar, temperate, and tropical 4 things affect climate: Latitude Elevation Closeness of water Closeness of mountains Cool air Warm air Desert Atmospheric Layers: ground up Troposphere…where weather occurs Stratosphere…ozone layer here Mesosphere…shooting stars burn up Thermosphere…ionosphere is here

4. Coriolis effect causes deflections of global wind patterns…know these patterns A hurricane is a low pressure counterclock- wise movement of air greater than 75 mph Barometer measures air pressure…falling=stormy weather Psychrometer measures humidity (how much moisture is in the air)100% =rain TRADE WINDS WESTERLIES POLAR EASTERLIES FRONT SYMBOLS Weather Instruments: KNOW HOW TO READ A WEATHER STATION MODEL Temperature Air Pressure Dew Point Wind direction NE Cloud Cover=50% 10 mph

5. Land Breezes and sea breezes are created by the differences in the heat capacity between water and land Cloud Types: Cumulus - tall cotton ball looking cloud Nimbus - means precipitation High Low High Winds are named by the direction they blow from Things that can change our atmosphere and eventually our weather ↑ in Carbon dioxide ↓ In ozone layer Volcanic activity & meteorite impacts GLOBAL WARMING

6. CAN YOU ANSWER THE FOLLOWING QUESTIONS? Wind is caused mainly by air-pressure differences that result from Rotation of Earth on its axis Radiation of heat from Earth’s landmasses to water bodies Uneven heating of the Earth’s atmosphere Absorption of ultraviolet radiation by Earth’s landmasses The barometric pressure is 913.0130.010.281013.0 The temperature is 3031-2845 Which letter is in the westerlies, which brings us our weather C F D B A high-pressure center is generally characterized by Cool, wet weather Warm, dry weather Cool, dry weather Warm, wet weather Most surface currents are caused by tides evaporation prevailing winds Salinity differences

7. Adjacent water and land surfaces have the same temperature at sunrise on a clear day, calm day. A surface wind develops after the water and land are heated by the Sun for a few hours. On which map do the arrows best represent the direction of this wind? Winds blow from regions of High air temperature to regions of low air temperature High air pressure to regions of low air pressure High precipitation to regions of low precipitation By which process are clouds, dew and fog formed? precipitationevaporationmeltingcondensation Which side of the mountain would be lush and green? leeward windward

8. What type of front extends eastward away from the low-pressure center? cold warm stationary occluded The arrows around point C represent the transfer of energy by conduction radiation convection precipitation
