Hint
It can be said that the cyclone is a system of winds rotating counter clockwise in the Northern Hemisphere around a low pressure center. The swirling air rises and cools, creating clouds and precipitation. There are two types of cyclones: middle latitude (mid-latitude) cyclones and tropical cyclones. A cyclone is a general term for a weather system in which winds rotate inwardly to an area of low atmospheric pressure. For large weather systems, the circulation pattern is in a counter clockwise direction in the Northern Hemisphere and a clockwise direction in the Southern Hemisphere.
Complete step by step answer
The eye is a region of mostly calm weather at the centre of strong tropical cyclones. The eye of a storm is a roughly circular area, typically 30–65 kilometres (19–40 miles) in diameter. It is surrounded by the eyewall, a ring of towering thunderstorms where the most severe weather and highest winds occur. The cyclone's lowest barometric pressure occurs in the eye and can be as much as 15 percent lower than the pressure outside the storm. In strong tropical cyclones, the eye is characterized by light winds and clear skies, surrounded on all sides by a towering, symmetric eyewall. In weaker tropical cyclones, the eye is less well defined and can be covered by the central dense overcast, an area of high, thick clouds that show up brightly on satellite imagery. Weaker or disorganized storms may also feature an eyewall that does not completely encircle the eye or have an eye that features heavy rain. In all storms, however, the eye is the location of the storm's minimum barometric pressure—where the atmospheric pressure at sea level is the lowest.
Therefore, the correct answer is Option (B).
Note
Let us clear our ideas on the concept that to form a cyclone, warm, moist air over the ocean rises upward from near the surface. As this air moves up and away from the ocean surface, it leaves less air near the surface. So basically, as the warm air rises, it causes an area of lower air pressure below.
On the other hand, technically, a cyclone is any kind of circular wind storm. Hurricanes occur in the Atlantic and typhoons, in the Pacific. Basically, hurricanes and typhoons form over water and are huge, while tornadoes form over land and are much smaller in size. The impact from cyclones extends over a wide area, with strong winds and heavy rains. However, the greatest damage to life and property is not from the wind, but from secondary events such as storm surges, flooding, landslides and tornadoes.
