The Formation of Major Weather Events Essay

Also there is an updraft of the lighter moist warm air from the ground, which keeps the thunderstorms from dissipating. While the warm air is rising there is cold dry air that is causing a downdraft causing the heavy water droplets to fall. The most violent storms are known as supercell storms, which are also the most likely to produce tornadoes. The last factor needed to produce the tornado is the jet stream to be moving at least 150 mph.

Tornados are one of the most destructive and devastating natural forces on Earth. When a tornado is fully created, wind speeds can reach up to more than 300 mph (483 km/h). Most tornadoes that occur are between the Appalachians and Rocky Mountains, but tornados can happen where ever the conditions are right. 90% of tornadoes that happen in the United States, happens in the Central United States. Even though scientist have not yet understood how tornadoes are formed, they’ve developed a theory that consist of the process and conditions of which a tornado must have to form.

The first thing that starts a tornado would be the winds. The wind updraft can form a funnel. This funnel is called a Mesocyclone and when the mesocyclone touches the ground it is considered a tornado. Clouds play an important role in forming tornadoes too. Some other clouds are called, Wall Clouds. These clouds protrude from the sky and look like a giant waves coming down about to crash on earth. When wall clouds form the sky might turn to a greenish color or some other color. This wall-cloud

When tornadoes do form; such places as the National Weather Service (2014) classify tornadoes into three categories. These categories are weak, strong, and violent. “

They are known as convective storms. Cell thunderstorms form in regions where limited vertical wind shear is present. The winds direction or speeds do not abruptly change rapidly. Ordinary storms develop and mature through a cycle, as cell thunderstorms don’t have this development. Different conditions vary from warm air rising, random turbulent eddies and terrain. These are a few that can be a trigger to these more impactful storms.

How tornadoes form you ask? Tornadoes form when different winds from different places met and form this giant spinning destructive cyclone which can be powerful or only cause minor damage. Tornadoes form when hot air from different places and cold air from different places collides which can make a tornado at any speed,

What is a tornado?A tornado is a narrow, violently rotating column of air that extends from the base of a thunderstorm to the ground. Because wind is invisible, it is hard to see a tornado unless it forms a condensation funnel made up of water droplets, dust and debris. Tornadoes are the most violent of all atmospheric storms.Where do tornadoes occur?Tornadoes occur in many parts of the world, including Australia, Europe, Africa, Asia, and South America. Even New Zealand reports about 20 tornadoes each year. Two of the highest concentrations of tornadoes outside the U.S. are Argentina and Bangladesh. How many tornadoes occur in the U.S. each year?About 1,200 tornadoes hit the U.S. yearly. Since official tornado records only date back to 1950,

Flooding is most frequently caused from substantial precipitation when waterways are full and the additional water has nowhere to go. Though rainfall isn’t always the cause of floods; they can be the outcome of other occurrences, mostly in coastal areas where inundation can be triggered by a storm surge linked with a tropical cyclone, a tsunami or a high tide corresponding with above average river levels.

Tornadoes are "small-scale circulations", the largest observed horizontal dimensions in the most severe cases being on the order of 1 to 1.5 miles. They most often form in association with severe thunderstorms which develop in the high wind-shear environment of the Central Plains during spring and early summer, when the large-scale wind flow provides favorable conditions for the sometimes violent clash between the moist warm air from the Gulf of Mexico with the cold dry continental air coming from the northwest. However, tornadoes can form in many different circumstances and places around the globe. Hurricane landfalls are often accompanied by multiple tornadoes. While tornadoes can cause much havoc on the ground (tornadic wind speeds have been estimated at 100 to more than 300 mph), they have very short lifetimes (on the order of minutes), and travel short distances.

Several conditions are required to have a tornado form. One said condition is warm, moist air and cold, dry air. When these mix, they create atmospheric instability. A change in wind direction and speed forms a supercell. Rising air creates a powerful vortex, which in turn creates a tornado. If you couldn’t understand the above text, the air mixes, becomes faster, and makes a tornado. This is the most common way tornadoes form, but they can form along with or inside

Tornadoes are very complex natural events. The tornado has to be the right size so that the tornado can release the rain at the precise amounts. If the tornado was too small the tornado would not produce enough heat to create a vacuum. The height from the ground is also a really important factor in the creation of a tornado. This is because the higher up the tornado is from the ground the more air the tornado will have rushing into it. These are just some of the many factors that have to be exactly perfect for a tornado to be naturally created and sustain the wind speed required for it to be a tornado.

     A tornado is a violent rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes can produce massive destruction with wind speeds of 250 miles per hour or more. The typical tornado moves from southwest to northeast, but they have been known to move in any direction. The average forward speed of a tornado is 30 miles per hour but it may vary from stationary to 70 miles per hour. Although tornadoes occur in many parts of the world, they are found most frequently in the United States east of the Rocky Mountains during the spring and summer months. In an average year, 800 tornadoes are reported nationwide, resulting in 80 deaths and over 1,500 injuries.

The components that creates a thunderstorm includes moisture, instability and a lifting mechanism. These components are what determines the severity of a thunderstorm as well as an abundant of vertical wind shear. If the wind is weak in speed and direction, thunderstorms won’t reach hazardous weather.

Tornadoes can also occur in many other areas of the world as well. They have been recorded in Australia, Europe, Africa, Asia, and South America as well as in North America. They occur mostly during the spring and summer; however, the tornado season comes early in the south and later in the north because spring comes later in the year as one moves northward. They usually occur during the late afternoon and early evening. However, they have been know to occur in every state in the United States, on any day of the year, and at any hour.

When thinking of lightning, the general thought is about a yellow streak of light zooming through the sky, however lightning can vary in size, color, pattern and many more things. One type of lightning is cloud to ground lightning with a negative charge. This type of lighting is a lightning discharge between a cloud and the ground started by a negatively charged stepped leader that is moving downward. Most lightning that hits the ground in a storm is, negative cloud to ground lighting. Positive ground to cloud is the same thing except it is started by a positive leader.
