Atmosphere

Question 1

Global Heat Budget

Answer 1

• Insolation is short wave radiation from the sun 100%
• Albedo affect
• 17% is refelted by clouds
• 8% is scattered by atmosphere gases and dust
• 23% is absorbed by atmosphere split into 19% by gases and 4% by clouds
• 52% is left
• 6% is reflected by earth surfaces
• 46% is absorbed by earth surfaces of the 46%, 6% is released by longwave radiation and 94% is released and absorbed by greenhouse gases

Question 2

Surplus and Deficit

Answer 2

• Curvature of the earth, larger surface area
• Albedo affect, surplus tropics + deficit poles
• Tilt of the earth 23.5, one pole get sunlight
• Oblique angle of the earth. energy to pole interacts with atmosphere and is reflected

Question 3

Ocean Currents

Answer 3

• Follow prevailing winds, frictional drag
• Deflected off of NA creates NAD
• Right in notheren hemisphere, coriolis force
• Dense polar water, Labrador Current
• Gyres large open areas

Question 4

3 Cell Model

Answer 4

• Warm rises amd condesnes forming low presuure
• It cools and travels to 30
• Returns as trade winds as air moves high to low
• Winds delfected to the right in NH due to coriolis
• Polar Cell, cold air sinks
