20
Q

What is a low pressure system also known as?

A

Low(L)

21
Q

Which direction does a low pressure system flow?

A

counter-clockwise

22

How are stationary fronts created?

A

Cold an warm air masses meet and neither front advances.

32
Q

What are stationary fronts represented by on weather forecasts.

A

Both Blue triangles and red semi-circles
