Geography 3/2 Key Concepts: Isolines/Isotherm/Thermal Equator/Annual temp range/Sea ice/Wind chill/Heat index/Hypthermia/Hyperthermis/Western Pacific Warm Pool/Ocean currents --Global Temperature Patterns- Isolines (from Greek isos ‘equal’). Used to show geographical patterns. Isotherm= Line of equal temperature. Interpolation= to insert information between data points. -Marine and Continental- Generally, over continents (marine): Isotherms bend equatorward in winter (marine-summer). Isotherms bend poleward in summer (marine- winter). -Land-Water heating differences- Marine effect- Martime. Narrow range along coastlines. Moderate temp patterns (cooler summers, warmer winters). Smaller seasonal range. Continental effect- Continentality. More extreme temps. Large seasonal range. -January Temperature- Thermal Equator= line connecting the highest mean temperatures (~27 degrees C but varies). Isotherms typically run East to West, interrupted by landmasses. North Pole- winter. South Pole- summer.

Unformatted text preview: -July Temperatures- North Pole- summer. South Pole- winter.-Arctic Sea Ice Changes-Positive feedback. -Recorded Temperature Extremes- Global high: 136 degrees F (58 degrees C) in Al Aziziyah, Libya September 1922. Global low: -128.6 degrees F (-89.2 degrees C) in Vostok, Antarctica July 1983. In USA: highest- In Death Valley, CA. 134 degrees F (57 degrees C) in 1913. 37 degrees N and 178 feet below sea level. Lowest- In Prospect Creek, Alaska 1971. -80 degrees F (-62 degrees C).--Temperature and the Human Body- We feel apparent temperature or sensible heat. Comfort level- Water vapor in the air, wind speed, air temp. Discomfort- High/low temp, high/very low humidity, low winds.-Heat Index- Correlates heat and humidity (water vapor in the air). More humid, less evaporative cooling. Hyperthermia- high body temperature, heat stroke which can be fatal. -Wind Chill- Correlates cold and wind speed. Hypothermia- The body loses heat, frostbite can be fatal if not treated....
