Hurricanes and tornados are some of the many natural disasters that plague our planet. Hurricane and tornados have differences on how they are formed and where they are formed. Also much damage they can cause when they appear. They also appear in my different sizes after they take physical form. Those are some of the many differences on hurricanes and tornados.
Hurricanes and tornados both need warm and cold air to become Hurricane or tornados but are different is in forming. Hurricanes usually start off their lives as clusters of clouds and thunderstorms called tropical disturbances.(HowHurr) A hurricane develops when warm air rises from the oceans and hits cold air and fuse, after fusing, the fused air forces the warm air into the atmosphere, which become the tropical disturbance. As the warm air is being forced out, a patent of wind which spiral up in the eye of the storm with water viper form the oceans keep on fueling this rotation until it become a hurricane. (youtube)
Unlike a hurricane that is form in the ocean a tornado is form on flat land. When cold and warm airs from different direction collide with each other they form a huge thunderstorm called a super cell. When air from two different altitudes begin to go at two different speeds they begin to form a funnel in between called a wind shear. (eo.ucar) When a part of the wind shear gets caught in the super cell upper draft, the speed of the upper draft will make the column go much faster curating a funnel cloud. (eo.ucar) When the funnel cloud is visible rain or hail from the storm will push down on the tail of the funnel cloud until it touches down on land making it a tornado.

...damage and deaths from both natural disasters by giving people warnings when they are about to appear. Both are very difference in shape and sizes and are very unpredictable on how big they will because once they take from and hit land. Hurricanes and tornados have always been natural disasters that plague our planet for many centuries now and with out a doubt will continue to wreak havoc on earth.

According to Webster’s Dictionary, a tornado is a rotating column of air accompanied by a funnel shaped downward extension of a cumulonimbus cloud and having a vortex several hundred yards in diameter whirling destructively at speeds of up to three hundred miles per hour. There are six classifications of tornadoes, which are measured on what is known as the Fujita Scale. These tornadoes range from an F0 to an F5, which is the most devastating of all. Abnormal warm, humid, and oppressive weather usually precede the formation of a tornado. Records of American tornadoes date back to 1804 and have been known to occur in every state of the United States.
Around 1,200 tornadoes hit the United States, most inside “tornado alley”, and during the main “tornado season” during spring and summer. As Earth’s tilt decides where the Sun will be, and what once was undisturbed air, now changed by gravity, can all lead to the production of a tornado. Mother Nature’s most dangerous and mysterious pheromones still unknown and still being researched. What else can cause the formation of tornadoes, beside Earth’s tilt and gravity? Meteorologist are still looking for the answer. Constantly learning more and more about tornadoes, maybe one day there will be a smaller death toll from tornadoes.
Tornadoes are “violent windstorms that take the form of a rotating column of air or vortex that extends downward from a cumulonimbus cloud” as Tarbuck and Lutgens (2012) explain.
A hurricane is easily the most powerful storm that mother-nature can throw at us. Every year people who live on the coasts fight hurricanes with no dismay. A hurricane is simply too strong. Their winds reach speeds of 75 mph. The winds around the eye wall can reach 130 to 150 mph. They are 200 to 300 miles in diameter. The number of casualties is endless, as well as the widespread destruction that takes millions of dollars to repair. Even if the hurricane doesn’t cause a lot of damage, the storm surge will. Storm surge is the great tidal waves that crash into our coasts and make huge floods that are caused by hurricanes.
Hurricanes are born over the warm waters of tropical oceans and are formed by a low-pressure system caused by the heating of water. The heat causes the air to rise and form lower pressures in a feedback loop, making the hurricane stronger. Heavy rain results from a condensation of water and strong winds develop from warm air rushing to the eye of the hurricane. Essentially, greater storms and winds occur when the hurricane feeds of the rising temperature of the water. In addition, researchers studied disturbances and intense thunderstorms in the atmosphere over Western Africa and believe they are partly to blame for extreme hurricanes affecting the United States and Canada. While these are all the main ingredients of a perfectly natural process, they were not the primary causes of the damage done by Hurricane
Hurricanes, also known as cyclones or typhoons, are huge, devastating tropical storms that can be up to 600 miles wide. They have strong, forceful winds that spiral inward and upward circling around the “eye” of the storm. Inside the eye, there are clear skies and light winds, however, surrounding the eye wall there are bands of wind and rain that spread out for over hundreds or thousands of miles. Hurricanes begin as tropical disturbances over warm ocean water (27°c or 80°F) and gathers heat and energy as it moves across the ocean. As evaporation from the ocean water increases its power, it changes into a tropical depression (wind speeds of less than 38 mph), then tropical storm (wind speeds of 39-73 mph) to finally a hurricane (wind speeds greater than 75mph). Hurricanes can last two weeks or more over open water and moves about 10-20 miles per hour. The safety of millions of people depends on the meteorologists and their ability to track these storms. Hurricanes may not be dangerous over open water, but are devastating when they hit land. They can cause torrential rains, high winds and storm surges as well as tornadoes, flash floods and land slides. Without warning of these hurricanes approaching, millions could die. The most effective tools meteorologists use are satellite images, radar and aircraft reconnaissance to study and warn people of approaching hurricanes.
Tornadoes are some of the most unpredictable weather we have on earth. Tornadoes belong to the category of meteorology in earth science. Meteorology is the science that deals with the weather and conditions. A tornado is a violent destructive whirling wind accompanied by a funnel-shaped cloud that progress in a narrow path over the land, (Merriam-Webster, 2014).
A tornado requires some basic ingredients to come together. First, energy in the form of warm, moist air must exist to feed thunder storms. Second, there must be a top layer of hot, dry air called a cap. This air acts like a lid on a simmering pot, holding in the warm air that’s accumulating in the atmosphere below until the storm’s ready to burst. Last, there has to be rotating winds speeding in oppositedirections at two different levels in the atmosphere, a phenomenon called wind shear, can cause the storms to rotate. Tornado alley is perfectly situated to meet these requirements. (1)
Hurricanes are one of the deadliest and most expensive natural disasters around. They are more common in areas of humid yet moist weather so they are very foreign to certain places. But to the places were hurricanes are the norm, the people take them extremely seriously because they kill people and ruin countless amounts of property. Hurricanes can attack and harm people in so many ways they can kill people, leave them homeless, it leaves children orphaned and disable them. On the west coast of the United States and other places hurricanes aren’t taken as seriously as other more common disasters, such as, earthquakes and volcanoes yet the hurricane can be a lot more damaging that both of those. Hurricanes are cyclones that develop over warm oceans and breed winds that blow yup to 74 miles per hour.
Hurricanes and tornadoes Floosh! My house is gone! Tornadoes and hurricanes can cause devastating damage. Tornadoes and hurricanes can be very different but they also have a lot of similarities, they both happen frequently, they have all different kinds of wind speeds, and they happen in certain locations.
There are many reasons why hurricanes are dangerous according to “How Dangerous are They?” by Scholastic, including wind damage, storm surge
1. According to the USA Today Tornado Information website, a tornado is a "violently rotating column of air in contact with the ground and pendant from a thunderstorm." Therefore, thunderstorms are the first step in the creation of a tornado.
Hurricanes are powerful atmospheric vortices that are intermediate in size. Hurricanes are unique and powerful weather systems. The word “hurricane” comes from a Caribbean word meaning “big wind”. Views of hurricanes can be seen from a satellite positioned thousands of miles above the earth.
Hurricane is a natural disaster with far reaching consequences. It takes away the lives of millions of people and causes damage to almost all of human creation. It can cause extensive damage to coastlines and several hundred miles inland due to heavy rainfall. Floods and flying debris often plays havoc in the lives of people living along coastal areas. Slow moving hurricanes produce heavy rains in mountainous regions. Landfall and mud-slides can occur due to excessive rain. Chances of flash floods also brighten due to heavy rainfall. Below are some interesting facts about hurricanes.
A hurricane is a type of natural disaster that can be harmful and destructive to anything in its way. Every year five to six hurricanes are formed, damaging and destroying people’s homes, landmarks, and anything in its path (“Hurricane”). Before a hurricane is developed it is known as a tropical storm. To be a tropical storm wind speed must be at least thirty eight miles per hour (“Hurricane”). Once wind speeds reaches seventy four miles an hour it can then be classified as hurricane (“Hurricane”). Large scale storms, like hurricanes have a variety of ways to measure the sev...
