Weather-producing fronts are parts of storm systems called Mid -Latitude cyclones. Mid-latitude cyclones are formed due to large temperature difference between the air-masses and the air masses blow in opposite directions.

Explanation:

The cyclonic storms with a diameter of 2000 kilometer and has low atmospheric pressure at the center are referred to as the Mid-latitude cyclone They are said to have cold front on the east and a warm front at the west side of the storm centerMid-latitude cyclones are formed due to large temperature difference between the air-masses and the air masses blow in opposite directions.The main  difference between a hurricane and a mid-latitude cyclone is that the hurricane have strong wind around the center or the eye of the hurricane but in case of a mid-latitude cyclones have their strongest winds aloft, in the jet stream
