HERE WE GO Climate describes the weather patterns for a given location over a Weather describes the period of years. day-to-day changes in Major climate zones are polar, atmospheric conditions temperate, and tropical Winds are created by the 4 things affect climate: uneven heating of the earth’s Latitude Closeness of water Elevation Closeness of mountains surface (remember we’re tilted on our axis…23.5°) WEATHER Winds blow from a high to a low Desert Atmospheric Layers: ground up Convection currents Troposphere…where weather occurs …hot air rises and cold Stratosphere…ozone layer here air sinks… is a major Mesosphere…shooting stars burn up Thermosphere…ionosphere is here cause of weather Coriolis effect causes deflections of global wind patterns…know these patterns A hurricane is POLAR EASTERLIES WESTERLIES TRADE WINDS FRONT SYMBOLS a low pressure counterclockwise movement of air greater than 75 mph Temperature Weather Instruments: Psychrometer measures humidity (how much moisture is in the air)100% =rain Barometer measures air pressure…falling=stormy weather 10 mph Air Pressure Dew Point Cloud Cover=50% KNOW HOW TO READ A WEATHER STATION MODEL Land Breezes and sea breezes are created by the differences in the heat capacity between water and land Winds are named by the direction they blow from High Low High Low Things that can change our atmosphere and eventually Cloud Types: our weather Cumulus - tall cotton ball looking cloud ↑ in Carbon dioxide ↓ In ozone layer Nimbus - means Volcanic activity & meteorite impacts precipitation GLOBAL WARMING CAN YOU ANSWER THE FOLLOWING QUESTIONS? Wind is caused mainly by air-pressure differences that result from Rotation of Earth on its axis Thefrom barometric pressure is to water bodies Radiation of heat Earth’s landmasses 913.0 130.0atmosphere 10.28 1013.0 Uneven heating of the Earth’s The temperature 31 -28 45 Absorption of ultraviolet radiationisby30 Earth’s landmasses Which letter is in the westerlies, which brings us our weather F B C D A high-pressure center is generally characterized by Cool,surface wet weather Most currents are caused by Warm, prevailing winds tides dry weather Cool, dry weather evaporation Salinity differences Warm, wet weather 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 By which air pressure processtoare regions clouds, of dew low air and pressure fog formed? High precipitation precipitation evaporation to regions of condensation low precipitation melting Which side of the mountain would be lush and green? windward leeward What type of front extends eastward away from the low-pressure center? cold warm occluded stationary The arrows around point C represent the transfer of energy by conduction radiation convection precipitation
