tropical cyclone upsc

Most large scale cyclonic circulations are centred on areas of low atmospheric pressure. A tropical cyclone is a rotating, organized system with winds, clouds and thunderstorms that originates over tropical or subtropical waters and has a closed low-level circulation. 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. If the ridge retreats eastward, there is a high … Continue reading "Re-curving cyclones" Context: Tropical Storm Hikaa develops into Cyclone.

The systems developing in the mid and high latitude (35° latitude and 65° latitude in both hemispheres), beyond the tropics are called the Temperate Cyclones or Extra Tropical Cyclones or Mid-Latitude Cyclones or Frontal Cyclones or Wave Cyclones. Wind speeds may exceed 119 km per hour, it may last from a few days to 3 weeks. The main cause of the development is the formation of the front mainly occluded front. How the names are chosen? Tropical Cyclone: A tropical cyclone is a destructive storm that originated in a warm ocean and winds circulate around low pressure. It is developed in mid and high latitude beyond the tropic means between 30 to 60-degree latitude in both hemispheres. What is a Tropical Cyclone? ...
