how many people have died due to this occurrence?

Tropical cyclone
The 1970 Bhola cyclone is considered to be the deadliest tropical cyclone on record, which killed around 300,000 people, after striking the densely populated Ganges Delta region of Bangladesh on November 13, 1970. Its powerful storm surge was responsible for the high death toll. The 
what are the effects of a tropical cyclone Heavy rain, strong wind, large storm surges near landfall, and tornadoes. what was its effect in us? The main cause of storm-related fatalities had been shifting away from storm surge and towards freshwater (rain) flooding. Despite advances in warning strategies and reduction in track forecast error, this increase in fatalities is expected to continue for as long as people migrate towards the shore. what happens at the center of this tropical disaster? At the center of a mature tropical cyclone, air sinks rather than rises. For a sufficiently strong storm, air may sink over a layer deep enough to suppress cloud formation, thereby creating a clear "eye". are there any warning centers? Yes, The United States National Hurricane Center, Fiji Meteorological Service, The United States Joint Typhoon Warning Center (JTWC) and Fleet Weather Center (FWC). what is the role of the second center? Its specialty is forecasting tropical cyclones south of the equator to the 25th parallel south, and between the 160th meridian east and 120th meridian west longitude and it issues public and marine weather bulletins for Kiribati, Northern Cooks, Southern Cooks, Tuvalu, Tokelau, Niue, Nauru and Fiji. do they have products for any disaster? Yes, Special Weather Bulletins (SWB's), Tropical Disturbance Advisories (TDA's), Special Advisory for Samoa, Tropical Cyclone Advisories (TCA's), Tropical Cyclone Sigmets, CREX bulletins and International Marine Warnings are a few. what is the first center responsible for? It is responsible for tracking and predicting tropical weather systems between the Prime Meridian and the 140th meridian west poleward to the 30th parallel north in the northeast Pacific Ocean and the 31st parallel north in the northern Atlantic Ocean. when was it formed? The first hurricane warning service was set up in the 1870s. what is carcah? Chief, Aerial Reconnaissance Coordination, All Hurricanes. what is its purpose? To provide a point-of-contact and to coordinate all tropical cyclone operational reconnaissance requirements at NHC and the Central Pacific Hurricane Center for the North Atlantic, Caribbean, Gulf of Mexico, and the North Pacific basin east of the International Date Line. how is the tropical disaster that was mentioned earlier forecasted? On the position and strength of high- and low-pressure areas, and predicting how those areas will change during the life of a tropical system. which are the notable ones that have occurred? Bhola, Nina, Thelma and Haiyan, to name a few. where did the first one occur? Ganges Delta region of Bangladesh.

Tropical cyclone [SEP] Notable tropical cyclones
Typhoon Nancy in 1961 also had recorded wind speeds of or , but recent research indicates that wind speeds from the 1940s to the 1960s were gauged too high, and thus it is no longer considered the storm with the highest wind speed on record. Likewise, a surface-level gust caused by Typhoon Paka on Guam in late 1997 was recorded at or . Had it been confirmed, it would be the strongest non-tornadic wind ever recorded on the Earth's surface, but the reading had to be discarded since the anemometer was damaged by the storm. The World Meteorological Organization established Barrow Island (Queensland) as the location of the highest non-tornado related wind gust at on April 10, 1996, during Severe Tropical Cyclone Olivia.
