  • Options
  • A. Temperate cyclones move from west to east with westerlies whereas tropical cyclones follow trade winds
  • B. The front side of cyclone is known as the 'eye of cyclone'.
  • C. Cyclones possess a centre of high pressure surrounded by closed isobars
  • D. Hurricanes are well known tropical cyclones which develop over mid latitudes.

  • Correct Answer
  • Temperate cyclones move from west to east with westerlies whereas tropical cyclones follow trade winds 

    Explanation

    Temperate Cyclones are cyclones of mid-latitudes and hence are primarily under influence of permanent winds of mid-latitudes i.e. westerlies. Their movement is therefore eastwards of their origin with average velocity of 32km per hour in summers and 48km per hour in winters.

    Movement of Tropical CyclonesNormally, they move from east to west under the influence of trade winds because trade winds are permanent winds of tropical latitudes. The general direction is therefore westwards from their origin. They advance with varying velocities. Weak cyclones move at the speed of about 32km per hour while hurricanes attain the velocity of 180km per hour or more.
