Hurricanes and Tornadoes
"Disaster, destruction, and distress" those are the sounds of a massive storm. Tornadoes and Hurricanes are some of the strongest storms on the planet, and I'm not talking about Earthquakes I'm talking about windstorms. Although these windstorms are different in many ways, they also have many similarities.
To start off with, when a Hurricane or Tornado is in the northern hemisphere they spin counter clockwise, but when in the southern hemisphere they spin clockwise. Both Hurricanes and Tornadoes are classified as cyclones, which are storms that spin with both hot and cold molecules mixing. Just like Hurricanes Tornadoes reach high speeds that could go up 300mph and maybe more!
Although, with similarities there
Hurricanes are formed over tropical waters. These intense storms consist of winds over 74 miles per hour (Ahrens & Sampson, 2011). The storms addressed here are Hurricane Katrina and Hurricane Sandy. This paper will explore the contrasts and comparisons between these two horrific storms.
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.
Tornadoes, also called twisters or cyclones, are a localized, violently destructive windstorm occurring over land, and characterized by a long, funnel-shaped cloud extending toward the ground and made visible by condensation and debris. They come in many different shapes and sizes, but are typical in a funnel formation, where the narrow end makes contact with the earth. Most don’t reach winds over 110 miles per hour (177 km/h) or have a path wider than 250 feet (76m), and most only travel a few miles on ground before dissipating. Although, some can reach winds as high as 300 miles per hour (483 km/h) or higher, have a path that can be as wide as two miles (3.2 km) or more, and can travel for dozens of miles on the ground before dissipating.
Hurricanes form over the ocean. Easterly waves, what hurricanes develop from, are long, narrow regions of low pressure which occur in ocean winds called trade winds. At first, these easterly waves can grow into something called, a tropical depression. A tropical depression occurs when winds are up to 31 mph. Then tropical depressions can be upgraded into a tropical storm if the winds reach speeds of 74 mph or less. Then finally a the storm can be bumped up into a hurricane if the winds reach 75 mph.
Hurricanes have been an active weather phenomenon throughout history. Thanks to our modern equipment, they are easy to track, yet still difficult to predict. Their destructive force causes millions of dollars in damage each time they hit land. We use male and female names to name them. They begin as many storm clouds over warm water and begin to form a tropical storm when enough of them gather. The rotating earth sets the storms in motion. The Coriolis Effect, which is the apparent deviation of an object, greatly influences the path of a hurricane, and must be taken into effect when trying to predict its path.
Hurricanes are large tropical storms occurring near or on the equator with large amounts of wind and rainfall, accompanied by high humidity and possible flooding. By definition, they must have a wind speed of 119 km/hr, or 74 mph. Technically, only tropical cyclones (the scientific term for hurricane) that form in the Atlantic or eastern Pacific are deemed “hurricanes”. They are formed in a chain reaction that starts with the ocean warming the moist air on its surface. Because warm air rises, the air heated by the ocean rises, leaving a low pressure gap underneath, allowing surrounding air to flow in. This process continues with the new air, and eventually, new air begins swirling into the low pressure zone. The previously-warmed air, now pushed up by the new air, begins to condense and form clouds. This is the nascent form of a hurricane, which may or may not fully develop. Hurricanes were first
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)
When people think of a tornado they may think of a vortex of spiraling winds reaching up to 200 mph. But when they think of a hurricane they may think of something very different but tornados and hurricanes have many similarities. Like how they have around the same costs and around the same casualties.
Picture this, you laying on top of you car as you are being violently slung down your street, which was once dry and calm and is now wet and foreign, at an extremely rapid pace. You can’t find your family and all you can do is hope that they haven’t drowned and are able to stay afloat against the violent waters that are angrily attempting to destroy everything in its path. You look around the weather is gray and it’s raining heavily. It is a struggle to breathe between the rapid rain and the violent waters which are attempting to pull you under, forever. Your house no longer exists it is broken down from the pounding waters and fast winds. That is exactly what it would be like if you were in the midst of a hurricane. After hurricanes are over the confusion is crazy, children who had loving families are now orphaned, people become homeless, and people miss certain joys such as walking due to becoming paralyzed.
Hurricanes begin as tropical disturbances in warm ocean waters with temperatures of at least 80 degrees Fahrenheit. These low pressure systems are served by energy from the warm seas. If a storm reaches wind speeds of 38 miles an hour, it is known as a tropical depression. A tropical depression becomes a tropical storm, and is given a name, when its sustained wind speeds top 39 miles an hour. When a storm’s sustained wind speeds reach 74 miles an hour, it becomes a hurricane and earns a category rating of 1 to 5 on the Saffir-Simpson scale.
First of all, I 'm going to give you some basic information on tornadoes. A tornado is a strong column of wind rotating around a center of low atmospheric pressure. Tornadoes look like large black funnels hanging from storm clouds. The winds inside a tornado can blow at speeds up to 500 miles per hour, but on average about 300 miles per hour. They are the fastest winds on earth. A tornado can form very fast, some even in less than a minute. Some people may say that a tornado is as loud as a train, but that isn 't always
For a hurricane to form, the ocean temperature must be warmer than twenty-six degrees Celsius, or eighty degrees Fahrenheit. Also, the air near the oceans surface must be filled with moisture. The seawater that is warmed by the heat from the sun evaporates to form vast storm clouds. As the warm air rises, the cooler air replaces it thus creating a wind. The rotation of the earth bends the wind inward causing it to rotate and spiral upward with a great amount of force. Around the Equator, the spin is the fastest. There, it can be faster than six hundred miles per hour.
The consistent message mainly sent by the media is that tornadoes are formed along the boundaries amid air masses like dry lines or cold fronts. However, the formation of tornadoes is associated with the clash of air masses. However, in reality, air masses are fond of clashing every time but in each situation, a tornado is not produced. Therefore, this explanation cannot be used to explain the formation of tornadoes since it is oversimplified and vague. The media draws its explanation from the cyclone model that is used to describe the formation of lesser pressures in the polar from, which is a region with warm tropical air adjacent to the cold polar air (Schultz et al.
A hurricane can be defined as than 64 knots (74 miles per hour; 119 kilometers per hour), originating in the equatorial regions of the Atlantic Ocean or Caribbean Sea or eastern regions of the Pacific Ocean, traveling north, northwest, or northeast from its point of origin, and usually involving heavy rains. Hurricanes are 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. It takes away the lives of millions of people and causes damage to almost all of human creation.
