Q:

What is the recipe to start the development of a hurricane?

A:

Quick Answer

The main ingredients in the recipe for the development of a hurricane are warm water, warm air and wind. As the warm water condenses in large gusts of wind, the water vapor rises and cools to form cumulonimbus clouds, the beginning stage of a hurricane.

Full Answer

Hurricanes generally form within 20 degrees either north or south of the equator, excluding the 5 degrees closest to the equator, because ocean temperatures less than 165 feet below the surface are at least 80 degrees Fahrenheit. When the water condenses and rises, it releases heat into the surrounding air. That air then also rises and is pulled into the cloud. As this process repeats, the air begins to pinwheel around, giving the hurricane its circular shape.

The first stage of a hurricane is called a tropical disturbance and occurs when this pinwheel joins with other clouds. The next stage, called a tropical depression, continues as increased air pressure at the top of the clouds causes the air pressure on the surface to drop. The storm becomes known as a tropical storm when the sustained winds exceed 39 mph. It becomes known as a tropical cyclone, another name for a hurricane or typhoon, when sustained wind speeds are 74 mph or above.

    What is the difference between a hurricane and a tornado?

    A:

    The main difference between a hurricane and a tornado is that hurricanes form over warm water while tornados form over land. As of 2014, the largest tornado ever recorded was 2.5 miles wide, while hurricanes can measure over 1,000 miles wide.

    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.

  • Q:

    What causes cyclones?

    A:

    According to Geoscience Australia, the main source for the generation of a tropical cyclone is the abundance of warm water and favorable wind patterns that can persist for several days as the cyclone develops. Encyclopedia Britannica explains that warm, moisture-saturated air continues to rise through the center of the circulation as long as the air surrounding the core is cooler and heavier. The continuous vertical movement allows clouds to develop.
