Impact of Ocean Circulation on Climate Change
The Arabian Sea's ocean circulation has been crucial for ancient sailors and plays a significant role in modern climate change. This circulation affects various regions, from Europe to Central Asia, influencing weather patterns, jet streams, and monsoon winds. As global warming alters these natural systems, repercussions are seen in wind patterns, ocean currents, snowfall, and floods. Exploring these changes helps us grasp the interconnectedness of Earth's climate systems.

Presentation Transcript
Sailing in the Arabian Sea A ocean circulation that was well known by ancient sailors AND is a key part of modern climate change.
PART 1 SUMMER JUMP TO WINTER JUMP TO WINTER
Europe Arabia Persian Gulf Canton, China Red Sea 0 Arabian Sea Indian Ocean
W 1 Central Asia is sunny and warm.
W 2 Jet stream goes north of Himalayas.
W 3 Trade winds blow west about 5oS.
W 4 Ocean water is pushed toward East Africa.
W L L 5 Air pressure over India is low. because land is warm and jet stream is north
W L L 6 Monsoon winds blow northeast. 7they bring a lot of rain to India!
W L L 8 Monsoon winds also push ocean water into the northern part of the Arabian Sea
W L L 9 That water escapes by flowing southeast along the coast.
10 The result is a clockwise cycle that sailors could use to travel around the Arabian Sea.
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.
PART 2 WINTER
Europe Arabia Persian Gulf Canton, China Red Sea 0 Arabian Sea Indian Ocean
C 1 Central Asia is cold.
C 2 Jet stream goes south of Himalayas.
C H H 3 Air pressure over India is high.
C H H 4 Monsoon winds blow southwest.
C H H 5 Ocean water is pushed southwest.
C H H 6 Trade winds blow west about 15oS.
C H H 7 Ocean water is pushed toward Madagascar.
C H H 8 Water piles up here and escapes to the east.
C H H 9 Water moves northwest along coast of India.
10 The result is a counterclockwise cycle that sailors could use to travel around the Arabian Sea.
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.
