These cyclones are generally accompanied by anticyclones. Four kinds of movement are involvedThe description of mid-latitude cyclones we’ve just provided is sometimes called the “Although the exact details vary from storm to storm, basic structure and movements of a midlatitude cyclone or Temperate cyclones we just described can help us understand the often abrupt weather changes we experience on the ground with the passing of one of these storms. They are infact low pressure centers produced in the middle latitude characterized by converging and rising air, cloudiness and precipitation. You can take Western disturbances that India face in winter as an example. More pronounced in Northern hemisphere due to greater temperature contrast. Tropical Cyclones and Temperate Cyclones -Comparison Tropical Cyclone Temperate Cyclone Origin Thermal Origin Dynamic Origin – Coriolis Force, Movement of air masses. Characteristics of Temperate Cyclones | UPSC IAS A typical mature mid-latitude cyclone or Temperate cyclones has a diameter of 1600 kilometers (1000 miles) or so. Comparison: temperate vs. tropical cyclones; UPSC Mains-2014 question about location of tropical cyclones and its answer South-east Caribbean region and North-west Australia fall in tropics where there is no converging of warm and cold air masses (that’s why temperate cyclones are also called as extra-tropical cyclones).Australia is between 15-38 degree N and Gulf of Mexico between 23 half and 30 degree N.So, in Gulf of Mexico as well there must be little chance of temperate cyclone .So,do they occur there or not?Though GULF of Mexico’s Tropical cyclone are more frequent rather Temperate.You see the spatial distribution of temperate climate varies with seasons (in summer it shifts towards north and in winter it shifts south). Varies from region to region.Less destruction due to winds but more destruction due to The movement of Cyclones in Arabian Sea and Bay of Bengal is a little different.I have no words to explain about ur notes more than excellent well defined digram and note. Typical size: 300 – 2000 kms in diameter. This is especially true when the cold front of a mid-latitude cyclone passes through in winter. Frontal system Absent The very cyclone … Confined to 350 - 650 N and S of equator.
Temperate cyclone also called as extra – tropical cyclone or wave cyclones or simply depressions, are atmospheric disturbances having low pressure in the center and increasing pressure outward. Frontal Cyclones: Occluded, stationary and dissipating front; Distribution of temperate cyclone in the world; Tropical cyclone: formation, mature stage, eye of tropical cyclone, properties and distribution. Latitude Confined to 100 - 300 N and S of equator. One thing i want to say kindly prepare the agriculture geography notes also .The favourite breeding grounds of temperate cyclones are:May be here no occluded front forms as no airmass exits due to warm current.Could you please explain why temperate cyclone doesnot form over these above two areas?The prerequisite for the formation of Temperate cyclones is the convergence of a warm and cold air masses. The temperate cyclones experience more rainfall when there is slower movement and a marked difference in rainfall and temperature between the front and rear of the cyclone. {{#message}}{{{message}}}{{/message}}{{^message}}Your submission failed.

For example in summer Gulf of Mexico will see tropical cyclones and in Winter they see Temperate cyclones. Midlatitude cyclones or Temperate cyclones are essentially transient features, on the move throughout their existence. Tropical cyclones range from 150-200 kms with high velocity where as temperate cyclones are larger in size ranging around 1900 km and due to large size it moves slower at the speed of 40-60 kmph. Such a condition is met only between 30 degree and 60-70 degree N and S (that’s why they are called temperate cyclones).
