Which one of the following may be the true characteristic of cyclones?
General KnowledgeGeography
- ATemperate cyclones move from west to east with westerlies whereas tropical cyclones follow trade winds.
- BThe front side of cyclone is known as the 'eye of cyclone'.
- CCyclones possess a centre of high pressure surrounded by closed isobars.
- DHurricanes are well-known tropical cyclones which develop over mid latitudes.
Explanation
Temperate (extratropical) cyclones move generally from west to east under the influence of the westerlies, while tropical cyclones are steered by the trade winds. The 'eye' is the calm central region, not the front side; cyclones are low-pressure centres, not high-pressure; and hurricanes develop over tropical oceans, not mid-latitudes. Statement A is therefore the true characteristic. Hence option A is correct.
