  1. 1) insolation per area: insolation per area: lower at poles 2.4 times lower at poles higher at equator than at equator zenith su sun ra rays ys co come me in para rallel Ma Marsh rshak: k: Ea Eart rth, Po Port rtra rait of a Pl Planet SIO15: Topic 15: The Atmosphere and Climate

  2. 1) insolation per area: insolation per area: lower at poles 2.4 times lower at poles higher at equator than at equator zenith sun rays come in parallel Ma Marsh rshak: k: Ea Eart rth, Po Port rtra rait of a Pl Planet SIO15: Topic 15: The Atmosphere and Climate

  3. 1) insolation per area: insolation per area: lower at poles 2.4 times lower at poles higher at equator than at equator zenith sun rays come in parallel Marshak: Earth, Portrait of a Planet SIO15: Topic 15: The Atmosphere and Climate

  4. 2) Earth’s rotation axis is zenith tilted 23.5º su sun ra rays ys co come me in para rallel Marsh Ma rshak: k: Ea Eart rth, Po Port rtra rait of a Pl Planet SIO15: Topic 15: The Atmosphere and Climate

  5. 3) summer: axis tilted so zenith that N pole facing sun su sun ra rays ys co come me in para rallel Marsh Ma rshak: k: Ea Eart rth, Po Port rtra rait of a Pl Planet SIO15: Topic 15: The Atmosphere and Climate

  6. 4) winter: axis tilted so that zenith N pole away from sun su sun ra rays ys co come me in para rallel Marsh Ma rshak: k: Ea Eart rth, Po Port rtra rait of a Pl Planet SIO15: Topic 15: The Atmosphere and Climate

  7. 5) if summer in N. hemisphere zenit -> winter in S. hemisphere h and vice versa sun ra su rays ys co come me in para rallel Marsh Ma rshak: k: Ea Eart rth, Po Port rtra rait of a Pl Planet SIO15: Topic 15: The Atmosphere and Climate

  8. 1) Earth’s rotation axis is tilted 2) tilted axis orbits Sun � sun in zenith at different times (+/- 23.5º N/ S) � local insolation changes throughout the year Marsh Ma rshak: k: Ea Eart rth, Po Port rtra rait of a Pl Planet SIO15: Topic 15: The Atmosphere and Climate
