Part i midlatitude cyclones: what are midlatitude cyclones, midlatitude cyclones in the great lakes region, famous midlatitude cyclones. Part ii research: toronto blizzard of 1999: gough (2000) In lecture 2 we examined the large scale circulation of the world. Midlatitude cyclones occur within the moving boundary of the ferrel and polar cells referred to as the. A series of low and high pressures propagate along the polar front. These lows are called midlatitude cyclones and largely characterize the weather conditions of the midlatitudes in the fall, winter and spring. During the summer the polar front often lies to the north of the great lakes region. Storms during the summer are either mid- latitude cyclones or convective storms arising from surface heating. Midlatitude cyclones, commonly referred to as low pressures, are the major source of weather variation in the midlatitudes (30 to 60 ). These storms occur approximately every four to seven days.
