  1. Sailing in the Arabian Sea A ocean circulation that was well known by ancient sailors AND is a key part of modern climate change.

  2. PART 1SUMMER JUMP TO WINTER

  3. Europe Arabia Persian Gulf Canton, China Red Sea 0 Arabian Sea Indian Ocean

  4. W 1 Central Asia is sunny and warm.

  5. W 2 Jet stream goes north of Himalayas.

  6. W 3 Trade winds blow west about 5oS.

  7. W 4 Ocean water is pushed toward East Africa.

  8. W L 5 Air pressure over India is low. because land is warm and jet stream is north

  9. W L 6 Monsoon winds blow northeast. 7 they bring a lot of rain to India!

  10. W L \ 8 Monsoon winds also push ocean water into the northern part of the Arabian Sea

  11. W L \ 9 That water “escapes” by flowing southeast along the coast.

  12. 10 The result is a clockwise cycle that sailors could use to travel around the Arabian Sea.

  13. 11? Today, as global warming causes the jet stream and the trade winds to shift in position, . . . . there are consequences for winds, ocean currents, snowfall in the mountains, and floods in the lowlands.

  14. PART 2WINTER

  15. Europe Arabia Persian Gulf Canton, China Red Sea 0 Arabian Sea Indian Ocean

  16. C 1 Central Asia is cold.

  17. C 2 Jet stream goes south of Himalayas.

  18. C H 3 Air pressure over India is high.

  19. C H 4 Monsoon winds blow southwest.

  20. C H 5 Ocean water is pushed southwest.

  21. C H 6 Trade winds blow west about 15oS.

  22. C H 7 Ocean water is pushed toward Madagascar.

  23. C H 8 Water “piles up” here and “escapes” to the east.

  24. C H 9 Water moves northwest along coast of India.

  25. 10 The result is a counterclockwise cycle that sailors could use to travel around the Arabian Sea.

  26. 11? Today, as global warming causes the jet stream and the trade winds to shift in position, . . . . there are consequences for winds, ocean currents, snowfall in the mountains, and floods in the lowlands.
