Topic #2 Revision

The amount of energy incoming from the sun that reaches the EARTH's surface

• Albedo

• Insolation

• Energy Budget

• Sensible Heat Transfer

The proportion of heat reflected back into the atmosphere

• Long wave radiation

• Sensible Heat Transfer

• Insolation

• Albedo

Most long wave radiation is lost:

• At night when it is cloudless

• During a sunny cloudless day

• At night when it is rainy

• Dependent upon the albedo of surfaces

During the night, water vapor close to the surface can condense to form water.

• Latent heat transfer

• Dew

• Condensation

• All of the above

The main difference between mist and fog is

• visibility

• air temperature

• amount of dew on the ground

• amount of clouds in the sky

Which of the following about mist or fog?

• cloud at ground level

• atmospheric instability

• dust or salt must be present in the air

• more common in coastal areas

This happens when there are calm conditions and high pressure. The movement of air causing cold and warm air to mix and affects the air quality causing air pollutants to stay close to the Earth's surface.

• dew

• temperature inversion

• advection fog

• radiation fog

Which hemisphere has the most intense pressure variations thus greater seasonal contrasts?

• Northern

• Southern

• Eastern

• Western

Permanent high pressure belts are located where?

• Polar regions

• Subtropical regions near equator

• Northern hemisphere

• in South east Asia

A band a few hundred kilometers wide in which winds from the tropics blow inwards, converge and then rise forming an area of low-pressure

• equatorial pressure zone

• subtropical pressure zone

• inter-tropical convergence zone

• polar pressure zone
