Full Answer

Typhoons form in warm waters and weaken when the water temperature goes below 79 degrees Fahrenheit. Typhoons develop slowly and mainly affect countries such as Vietnam, Japan and southern China. Typhoons cause storm surges and heavy rain and bring high winds.

A typhoon consists of spiral rain bands, an eye wall and an eye. The eye is a region of calm within the entire storm. Surrounding the eye is the eye wall, a region with high winds and heavy rain. Spiral rain bands wrap around the eye in the same direction as the winds.

  • Q:

    How does a typhoon start?

    A:

    A typhoon starts when a storm is magnified by warm tropical or sub-tropical ocean water. As the storm draws moisture from the water, the heat increases winds and speeds the rotation of the storm. Once winds hit 74 miles per hour, it becomes a typhoon.

  • Q:

    How does a typhoon form?

    A:

    Typhoons form in the tropical oceans when areas of high pressure rush toward areas of low pressure, which creates wind. When the storm begins to rotate and organize around an "eye" of low pressure, it is well on its way to becoming a typhoon. Storms are categorized as typhoons when they reach wind speeds of 74 miles per hour.
