Mid-latitude Cyclone Exercise
Try doing the following without looking at your book or notes.
1.
Draw out a mid-latitude cyclone.
Start with an “L” signifying your low pressure center.
2.
Add in fronts around your “L” where the warm front and cold front are, assuming no
occlusion occurred (it’s in the mature stage).
Be sure to have the correct symbols on each
of your lines!
3.
Label the warm sector of the mid-latitude cyclone.
4.
Label the wind directions in three areas: at the approaching warm front, within the warm
sector, and behind the cold front.
5.
Label the cloud type and sky coverage at each of the three locations: at the approaching
warm front, within the warm sector, and at the approaching cold front.
