Stage of formation of the temperate cyclone : The main cause of the development is the formation of the front mainly occluded front. How are cyclones named? In News: NIVAR Cyclone made a landfall 30 km north of Puducherry and 115 km south of Chennai on the night of 25th November. 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. What is a Tropical Cyclone? In Northern Hemisphere, recurvature of a tropical cyclone is defined as the situation when a tropical cyclone transits from a mainly westward track to a northward and sometimes even an eastward track. ; The Indian Meteorological Department (IMD) said that the tropical storm has weakened from a ‘Very Severe Cyclonic Storm’ to a ‘Severe Cyclonic Storm’ with a wind speed of 100-110 km per hour,; As per IMD predictions, it would continue to move … Tropical Cyclone: A tropical cyclone is a destructive storm that originated in a warm ocean and winds circulate around low pressure. Tropical cyclones are what most people are familiar with because these are cyclones that occur over tropical ocean regions. They are infact low pressure centers produced in the middle latitude characterized by converging and rising air, cloudiness and precipitation. Based on their latitude, the cyclones may be tropical cyclones or temperate cyclones (extra-tropical … will find this geography quiz on cyclones and … Context: Tropical Storm Hikaa develops into Cyclone. Most large scale cyclonic circulations are centred on areas of low atmospheric pressure. ESSAY TEST SERIES 2021- UPSC IAS MAINS Examination A strong subtropical ridge usually steers a tropical cyclone to move along its periphery. For cyclones in the Bay of Bengal and Arabian Sea, the naming system was agreed by eight member countries of a group called WMO/ESCAP and took effect in 2004. 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. As per Ferrel law, it rotates anticlockwise wise in the northern hemisphere and clockwise in the southern hemisphere. The tradition of naming cyclones started with hurricanes in the Atlantic Ocean, where tropical storms that reach sustained wind speeds of 39 miles per hour were given names In 1953, the US weather service officially adopted the idea and created a new phonetic alphabet (international) of women’s names from A to W, leaving out Q, U, X, Y and Z. A Cyclone represents a rotating, organized system of clouds and thunderstorms that originates over tropical or subtropical waters and has closed low-level circulation.

If the ridge retreats eastward, there is a high … Continue reading "Re-curving cyclones" It is developed in mid and high latitude beyond the tropic means between 30 to 60-degree latitude in both hemispheres. Origin and Development of Temperate Cyclones Polar Front Theory According to this theory, the warm-humid air masses from the tropics … How the names are chosen?
