Gr 12 T1: Mid-latitude cyclones

A large body of air that has generally uniform conditions of temperature and humidity is known as a(n)

• frontal boundary

• thermal

• air mass

• mid-latitude cyclone

This forms when warm air slowly moves into an area covered by cooler air.

• warm front
• cold front
• stationary front
• occluded front

The diagram shown represent a(n):

• occluded front

• warm front

• stationary front

• cold front

Middle latitudes are considered to be between:

• 30-60 degrees

• 60-90 degrees

• 0-30 degrees

• on the equator

Cyclones are centers of __________ pressure.

• High

• Low

• Warm

• Cold

Air rotates around a Mid-Latitude Cyclone in a _____________ and _____________ direction in the Southern Hemisphere.

• Clockwise and inward

• Clockwise and outward

• Anticlockwise and outward

• Anticlockwise and inward

Cold fronts move over the Western Cape....

• all year

• mainly in summer

• mainly in winter

• not at all

The latitude of Mid latitude varies

• with the seasons.

• with the movements of the pressure belts.

• with the movements of the ITCZ

• all the answers are correct

Study the plan view of and the cross-section through a mid-latitude cyclone in Figure 2.

Q - In which general direction does this cyclone move in the Southern Hemisphere?

(a)  

Why does the warm front (C) have very little influence on the weather of South Africa?

• South Africa usually has warm weather.

• The warm sector of air does not pass over South Africa

• The warm sector of the cyclone is visible behind the warm front
