Range Equatorial areas receive the direct rays of the Sun for most of the year. Therefore, the yearly temperature does not change much. Temperature Low Latitudes Mid Latitudes High Latitudes JFMAMJJASOND

Month Latitude - Yearly Temperature Range As latitude increases, yearly temperature range increases 0 90

Latitude Altitude - Average Yearly Temperature Range Altitude - the height of an object above sea level. Low average yearly temperature range High average yearly temperature range

Altitude - Average Yearly Temperature As altitude increases, average yearly temperature decreases Altitude Ocean Currents Ocean currents move warm water from

the equator towards the poles. Ocean currents move cold water from the poles back to the equator to be heated again. (pg. _4_ of ESRT) Animatio n Ocean Currents Marine vs. Continental

Sea or land locations affects temperature ranges. Since land gains and loses heat much more quickly than water, land areas tend to have warmer summers and cooler winters. Coastal areas near the ocean have cooler summers and milder/warmer winters. Coastal areas have marine climates with a small yearly temperature range and areas inland have continental climates with a larger yearly temperature range

Marine Vs. Continental This graph shows the average monthly temperatures for two cities, A and B, which are both located at 41N latitude. Why is there a difference in the average yearly temperature range for the two cities? Because City A is located

inland (continental) and Interactive Climate Map City B is located near water Rainfall Factors - Latitude Uneven heating of the Earth produces global wind & pressure belts. These belts determine the wetness or dryness

of an area. Low Pressure - rising air creates precipitation High Pressure sinking air creates a lack of precipitation Animation Latitude Continued

El Nino A warming of the surface water of the eastern and central Pacific Ocean, occurring every 4 to 12 years and causing unusual global weather patterns. El Nino brings heavy rain to western South American and drought to eastern Australia and Indonesia. Animatio
