- Why And How Of Hurricanes
By: Brian Jones | - A hurricane is a naturally-occurring violent tropical storm characterized by spiraling winds of high speed and great destructive power. The diameter of the wind spiral may reach into several hundred miles. Hurricanes develop from large warm bodies of water and then move towards land at a speed of ten to thirty miles per hour. Hurricanes can produce torrential rainfalls, high waves and storm surges.
The term hurricane is used for tropical storm that occurs in North Atlantic and Nor ...

Several atmospheric ingredients must come together for a hurricane to form. There are perhaps seven atmospheric conditions which, if met, could cause a hurricane to form. A pre-existing disturbance, warm ocean water, low atmospheric stability, sufficient Coriolis force, moist mid- atmosphere, and upper atmosphere divergence are all important factors for hurricane formation. These conditions are discussed in greater detail in another article by Rich ...

- How Do Hurricanes Form?
By: Rich Johnson | - Hurricanes usually form in the summer or early autumn when several key atmospheric ingredients come together. Contrary to common belief, many factors other than warm ocean water cause hurricanes to form. In fact, the water is always warm enough in the deep tropics for hurricanes to form all year long. During the winter and spring, upper air winds are hostile, and usually do not allow tropical cyclone development. So, what does it take for a hurricane to form?
1. Pre-existing ...

- Does Global Warming Affect Hurricanes?
By: Rich Johnson | - Global Warming is a term denoting a gradual warming of the Earths average temperature. The term has become synonymous to the Earths warming exclusively due to man-made effects, especially carbon dioxide. Carbon dioxide concentrations have increased from 300 parts per million to 384 parts per million since 1900, with the most accelerated increase during the past 40 years. Some scientists have drawn the conclusion that the increase in the Earths average temperature (about 1F since 1975) is es ...
