Q:

How does a typhoon form?

A:

Quick Answer

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.

Full Answer

The process begins when the surface of the ocean heats up. The higher temperatures and humidity levels over the ocean create disturbances in air pressure. When these disturbances strengthen, the wind begins to spiral toward a center of low pressure, drawing moisture to the center, which forms the eye. When the storm becomes organized, it develops into a tropical depression. Once wind speeds reach 39 miles per hour, it becomes a tropical storm.The eye of low pressure develops, and the storm begins to rotate and gain in strength. The storm becomes a typhoon when it reaches wind speeds of 74 miles per hour.

Storms that develop around North and Central America are known as hurricanes. Storms that develop in the Northwest Pacific are known as typhoons. The spiraling in the storm is caused by the Earth's rotation, and because the winds curve, these storms cannot form on or near the equator. A storm must be at least 300 miles away from the equator to develop into a typhoon.

    How does a vortex form?

    A:

    Whether it's a bathtub draining or a spinning tornado, vortexes are caused by downdrafts that form when high pressure and low pressure interact. The conflict results in the creation of a swirling suction that, in the case of a tornado, can be very destructive.

  • Q:

    How are hurricanes made?

    A:

    Hurricanes are made when tropical storms form over sections of the ocean with warm, moist air and enough wind to begin a spiral. The primary cause is the latent heat from water evaporating off the surface of the ocean, which causes atmospheric imbalances that can increase wind speeds to hurricane levels. These can be higher than 150 miles an hour around the hurricane's eye.

  • Q:

    What causes a typhoon?

    A:

    Typhoons are cyclonic tropical storms caused by a combination of warm water, evaporation, swirling winds and other factors. They typically start as smaller more mundane storms, but under the right conditions they may grow into monster coastline-wrecking typhoons.
