In  meteorology , a  cyclone  is a large scale  air mass  that rotates around a strong center of low  atmospheric pressure .   Cyclones are characterized by inward  spiraling   winds  that rotate about a zone of  low pressure .  The largest low-pressure systems are  polar vortices  and  extratropical cyclones  of the largest scale (the  synoptic scale ). Warm-core cyclones such as  tropical cyclones  and  subtropical cyclones  also lie within the synoptic scale.   Mesocyclones ,  tornadoes  and  dust devils  lie within smaller  mesoscale,  Upper level cyclones can exist without the presence of a surface low, and can pinch off from the base of the  tropical upper tropospheric trough  during the summer months in the  Northern Hemisphere . Cyclones have also been seen on extraterrestrial planets, such as  Mars  and  Ne...

Cyclone Fani—pronounced "Foni"—is gaining strength over the southeast Bay of Bengal and will soon develop into an "extremely severe cyclonic" storm. The name for this cyclone was suggested by Bangladesh, reports India Today.  The World Meteorological Organisation (WMO) has devised a mechanism where countries submit it a list of names from time-to-time. Cyclone names are chosen from this pool. For tropical cyclones developing in the North Indian Ocean, countries—like India, Sri Lanka, Bangladesh, Maldives, Myanmar, Oman, Pakistan, and Thailand—send in their names to the regional tropical cyclone com...
