Mid Latitude Cyclone in Southern Hemisphere
A mid latitude cyclone can also be referred to as an extratropical cyclone. As the name mid latitude suggests, they are found outside the tropics but before the north and south poles, approximately between 23 and 66 degrees on each of the hemispheres or the temperate zones of the earth between the Antarctic and the Arctic Polar Regions and the tropics. A cyclone on the other had refers to a location that is characterized by the existence of low pressure where the wind blows clockwise and anticlockwise in the southern hemisphere and northern hemisphere respectively. It is an area filled with fluid rotating in a circular motion as a result of the earth’s rotation. Mid latitude cyclones are formed as a result of degree of difference in heating from the sun. There are various stages involved in the formation of a mid latitude cyclone. In this context for instance, when the world is tilted on its axis during the winter season, the southern hemisphere receives minimal sunlight due to the limited angle of the sun hence the region becomes very cold. The tropics on the other hand experience more solar radiation due to the direct angle of the sun. Therefore, this scenario forms an imbalance. The result is a formation of a “Polar front” which can also be referred to as the “dividing line” between the two atmospheres. It separates extremely warm air to the north and extremely cold air to the south in the case of the southern hemisphere. They have to stabilize out the massive heat that exists close to the equator and the cold air close to the poles. The warm air tries to move towards the south while the cold air tries to move towards the north. As a result mid latitude cyclones are formed to restore the balance in the regions affected by this scenario. A kink is formed during this process when the warm air is moving southwards and the cold air mass is heading northwards. At this...
