Fluorosis is a cosmetic condition that affects the teeth. Itâs caused by overexposure to fluoride during the first eight years of life. This is the time when most permanent teeth are being formed. After the teeth come in, the teeth of those affected by fluorosis may appear mildly discolored.
The eye that shows up in mature hurricanes represents the center of the storm. Counterintuitively to some, the eye represents an area of the hurricane where there is little to no precipitation, the sun or stars can be visible for a time, and the winds are light.Also within the eye is the lowest barometric pressure associated with the hurricane.The eye of a hurricane can range in size from about 5 miles (8 km) up to as wide as 120 miles (200 km) in diameter; however, a typical size is usually about 20-40 miles (30-60 km).he eye that shows up in mature hurricanes represents the center of the storm. Counterintuitively to some, the eye represents an area of the hurricane where there is little to no precipitation, the sun or stars can be visible for a time, and the winds are light.
Similar to the eye seen in hurricanes or typhoons, it is a circular area at the circulation center of the storm in which convection is absent. These eye-like features are most normally found in intensifying tropical storms and hurricanes of Category 1 strength on the Saffir-Simpson scale.hough the eye is by far the calmest part of the storm, with no wind at the center and typically clear skies, over the ocean it is possibly the most hazardous area. In the eyewall, wind-driven waves all travel in the same direction.
