The patterns and conditions under which hurricanes develop

Use the Internet to research a severe weather pattern of interest. Collect data on several key components of their severe weather pattern and address the following questions: Under what conditions does the severe pattern form? Where is it most likely to occur geographically?

The patterns and conditions under which hurricanes develop

These giant storms, which form over the Atlantic Ocean and eastern Pacific Ocean, unleash fury on their surroundings. The United States is threatened by hurricanes from June 1 through Nov. Due to this relatively long hurricane season, it is important to understand the weather conditions that create a hurricane, especially to those who live on the coasts and in areas where hurricanes are most likely to hit.

Understanding the weather conditions that create a hurricane is the first step in preparing to weather one's onslaught. As this warm water meets the wind that blows west from Africa across the ocean, it causes the water to vaporize.

The water vapor then rises into the atmosphere, where it cools and liquefies. As it liquefies, it creates clouds called cumulonimbus clouds, which are tall columns of clouds that generate bands of thunderstorms--the perfect weather conditions to create a hurricane.

A cycle begins when rain from the thunderstorm falls to the ocean, where it is reheated and sent back into the atmosphere, giving increased energy to the growing hurricane. Hurricanes are generically called tropical cyclones, which have four stages: A tropical disturbance occurs when the water vapors from the warm ocean water first rise and then condense in the atmosphere, releasing heat and thus energy to begin powering a hurricane.

As this process continues, cumulonimbus clouds are formed into long columns extending high into the atmosphere. When the clouds build, wind begins forming around a center point. As it moves across the ocean, this storm creates more and more thunderstorms, forming a tropical disturbance.

As the cumulonimbus clouds force thunderstorms to higher elevations, the air at the top of the columns begins to cool, releasing energy in the form of heat.

This warms the clouds beneath it and causes wind to move away from the center of the storm in a spinning fashion. As this is repeated, the winds pick up speed, ranging anywhere from 25 to 38mph. A tropical storm follows a tropical depression when winds measure more than 39mph. The process for tropical storm formation is the same as the process for a tropical depression, with winds continuing to blow at faster speeds and circulating around the eye of the storm.

Finally, a tropical cyclone, most often referred to as a hurricane when it is over the Atlantic Ocean, takes place when the speed of the wind reaches 74 mph or more.

Warm Ocean Water

At this point, the hurricane reaches 50, feet or more into the atmosphere and is at least miles across. Winds that move from east to west, known as trade winds, push the hurricane westward.

Feb 14,  · This of course is not the case; if it were, the weather would be very different. The local weather that impacts our daily lives results from large global patterns in the atmosphere caused by the interactions of solar radiation, Earth's large ocean, diverse landscapes, and motion in space. Hurricanes are one of nature’s most aggressive and impressive acts. These giant storms, which form over the Atlantic Ocean and eastern Pacific Ocean, unleash fury on their surroundings. The United States is threatened by hurricanes from June 1 through Nov. It may surprise you to know that very few of the storms over warm water develop into hurricanes. There are many factors that need to be present in the environment before a full-fledged hurricane forms.

This is why so many hurricanes hit the Caribbean, Gulf of Mexico and the coastal regions in the southeastern United States.

As they hit land, hurricanes typically lose strength, because they are no longer over the warm waters required to fuel them.

Exceptional Weather - Tropical Cyclones

However, they still pose a significant threat to the areas over which they make landfall, in the form of wind and water damage. She writes for several websites.Meteorology study guide by fsubarnes includes questions covering vocabulary, terms and more. The conditions that persist along the West Coast of the U.S.

that are conducive to fog formation are. Hurricanes often develop in late summer when waters reach. 27 C.

What Are the Three Weather Conditions Under Which a Tropical Cyclone Usually Develops? | Sciencing

Why don't hurricanes develop near the equator. Storms that form north of the equator spin counterclockwise. Storms south of the equator spin clockwise.

This difference is because of Earth's rotation on its axis. As the storm system rotates faster and faster, an eye forms in the center. It is very calm and clear in the eye, with very low air pressure.

Due to this relatively long hurricane season, it is important to understand the weather conditions that create a hurricane, especially to those who live on the coasts and in areas where hurricanes are most likely to hit.

Weather Underground provides local & long range Weather Forecast, weather reports, maps & tropical weather conditions for locations worldwide. It may surprise you to know that very few of the storms over warm water develop into hurricanes.

There are many factors that need to be present in the environment before a full-fledged hurricane forms. Have students pick one of the following severe weather patterns to study using printed or on-line resources: Tornadoes; Hurricanes; Floods; Lightening, Hail, and Thunderstorms.
