1913 (October) Muktagachha upazila (Mymensingh); cyclonic storm; demolished many villages killing about 500 persons. The term 'cyclone' is at times applied to a mid-latitude depression but is now increasingly restricted to a tropical depression of the hurricane type, especially when it occurs in the indian ocean.

Weather satellites in cyclone warning Bangladesh does not have satellite facilities of its own, but with the help of ground stations, it receives weather pictures from weather satellites launched by advanced countries. Pressure at the centre of the low may be 50-60 hPa (Hexa Pascal) less than in its outskirts. The tail usually crosses the land well before the main core of the cyclone and as a result the sky becomes overcast with clouds and rain often sets in before the onset of a cyclone. . 1963 (28-29 May) Chittagong, Noakhali, Cox's Bazar and the offshore islands of Sandwip, Kutubdia, Hatiya and Maheshkhali were badly affected; severe cyclonic storm with storm-wave rising 4.3-5.2m in Chittagong, maximum wind speed 203 km/hr and at Cox's Bazar 164 km/hr; more than 11,520 people killed, 32,617 cattle lost, 376,332 houses, 4,787 boats and standing crops destroyed. In the West, hurricanes are identified with human names such as Mitchel, Andrew, Carol, Dorothy and Eve. Cyclones are usually formed in the deep seas and hence their study has been very difficult.

Data from NOAA satellites are obtained every six hours. The main core of the cyclone is circular or nearly circular, having a diameter ranging from 100 km to 800 km. All fishing boats have been asked to take immediate shelter until further notice. Amphan is likely to make landfall in Bangladesh tomorrow with maximum sustained wind speed of 155-165kmph, with gusts of up to 185kmh.
In cyclone forecasting, it is often assumed that a cyclone follows the direction of the upper atmospheric current. The maximum recorded wind speed of the 1970 cyclone was about 222 km/hr and the maximum storm surge height was about 10.6m and the cyclone occurred during high-tide. 1975 (9-12 May) Bhola, Cox's Bazar and Khulna; severe cyclonic storm with a wind speed of 96.5 to 112.6 km/hr; 5 persons killed and a number of fishermen missing. Classification Cyclones in Bangladesh are presently classified according to their intensity and the following nomenclature is in use: depression (winds upto 62 km/hr), cyclonic storm (winds from 63 to 87 km/hr), severe cyclonic storm (winds from 88 to 118 km/hr) and severe cyclonic storm of hurricane intensity (winds above 118 km/hr). 1988 (24-30 November) Jessore, Kushtia, Faridpur, offshore islands and chars of Barisal and Khulna; severe cyclonic storm with core wind speed 162 km/hr, storm surge of 4.5m at Mongla point; killed 5,708 persons and lot of wild animals - deer 15,000, Royal Bengal Tiger 9, cattle 65,000 and crops damaged worth about Tk 9.41 billion.

This contributed to a tropical depression that formed November 8th, 1970 in the Bay of Bengal. Cyclones in the Bay of Bengal Because of the funnel shaped coast of the Bay of Bengal, Bangladesh very often becomes the landing ground of cyclones formed in the Bay of Bengal. The diameter of a cyclone may range from 300 km to 600 km. On 15 November 2007, Cyclone Sidr with wind speeds of up to 260 km/hour made landfall in southern Bangladesh, causing over 3,500 deaths and severe damage. 1961 (9 May) Bagerhat and Khulna; severe cyclonic storm with a wind speed of 161 km/hr, surge 2.44-3.05m; rail track between Noakhali and Harinarayanpur damaged, heavy loss of life in Char Alexander, 11,468 people killed and about 25,000 cattlehead destroyed. The eye is small and almost circular; it coincides with the area of lowest pressure and has a diameter ranging from 8 km to 50 km. Moreover, the upper atmospheric current is as variable as the tract of the cyclone. The duration of a cyclone, from the beginning to the end, may range from 7 to 10 days and it may produce 25 cm to 50 cm of rainfall.

People were interviewed after the event, and they described horrific scenes of watching their children being swept away by the strong current. It is likely to make landfall as a strong storm equivalent to a category 3 hurricane, according to the Indian Meteorological Department.

The life cycle of a cyclone ends soon after the cyclone reaches land ('landfall'), because it is cut off from its moisture source. The authorities were able to evacuate more than 2 million people to shelters before cyclones Fani and Bulbul made landfall. The central overcast cloud had a diameter exceeding 600 km.
The eye can be seen clearly in satellite pictures in the case of a well-developed cyclone. Although there were not direct measurements of the winds of pressure in the storm, satellite imagery suggests that the storm intensified rapidly, becoming a well-defined cyclone with sustained winds between 137-145 km/h (85-90 mph) by 11 November. The spiralling winds converge toward the centre of the low pressure where they rise at a tremendous speed. 1991 (29 April) The Great Cyclone of 1991, crossed the Bangladesh coast during the night. 1897 (24 October) Chittagong; hurricane reached maximum intensity with series of storm-waves; Kutubdia Island and coastal villages were swept over, 14,000 people killed and 18,000 died in epidemics (cholera) that followed.

1974 (24-28 November) Coastal belt from Cox's Bazar to Chittagong and offshore islands; severe cyclonic storm with a wind speed of 161 km/hr and storm surge of 2.8-5.2 m; 200 people killed, 1000 cattle lost and 2,300 houses perished.

In each ward the trained volunteers are ready to do the needful in the event of a cyclone. The cyclone of 29 April 1991 hit Chittagong, Cox's Bazar, Barisal, Noakhali, Patuakhali, Barguna and Khulna along with a tidal bore (6.1m to 7.6m), killing 140,000 people. 1941 (May) Eastern Meghna estuary; cyclonic storm with storm-wave; exact figures of the loss of lives and cattle aer not available. On an average, 80 tropical cyclones are formed every year all over the globe.

It is categorized as an “Extremely Severe Cyclone.”. Tropical storms are called hurricanes in the American continent, typhoons in the Far East and cyclones in the South Asian subcontinent. Nov 12, 1970 - The storm begins to move with increased speed north-northeast with estimated winds of 205km/hr. Reports from ships within the storm and in its proximity report to the Indian Meteorological Department and Pakistani Meteorological Service.
