Document Summary
Isotherm: thermal equator, annual temperature range, sea ice, wind chill, heat index, hypothermia, hyperthermia, western pacific warm pool, ocean currents. Interpolation- to insert information between data points (to decide where the lines go, mathematical process: figure 5. 13. Isotherms bend towards or away from the equator. Marine and continental: generally over continents: isotherms bend equatorward in the winter and isotherms bend poleward in the summer, generally over marine: isotherms bend equatorward in the summer and isotherms bend poleward in the winter. Sea surface temperature: animation is on moodle, shows equator temperatures, water is warmer near the equator, western hemisphere warm pool - stays warm year round. Ocean currents: figure 6. 21, ocean currents directly affect sea temperatures, currents move in circles, as it flows north, it loses energy and becomes cooler, water flows south, gains energy, becomes warmer near the equator, cold air creates fog.
