Document Summary
Midlatitude cyclones occur within the moving boundary of the. Ferrel and polar cells referred to as the polar front. Low and high pressures propogate 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. Polar front often lies to the north of the great lakes region. Midlatitude cyclones which often occur as a result of surface heating. Major weather maker in the midlatitudes (35-60) Most storms in southern ontario in the fall, winter and spring , are midlatitude cyclones. They tend to occur between a cold polar air mass (cp) and a moist. Less intense winds tropical air mass (mt) , the warmth and latent heat (water vapour) provide energy for the storm. Are typically 100s to 1000s of km in extent (larger than hurricanes) , but have less intense winds than hurricanes,
