Geographical Circumstances Causing Thunderstorms

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

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.

So the warm moist air creates clouds of rain and thunderstorm. Adding to that winds with different speed going in different directions assisting in expanding these great clouds of rain and thunderstorm. With

A tornadoes form when it is humid but the ground is wet and slower winds are by the ground as the fastest wind are higher in the sky. Because of this the wind starts to circle around when the slow wind moves up higher. Rain will fall and so will a funnel which is the tornado. The reason twister in Florida left extreme damage and many houses were being fixed or covered with tarp. Today they are cleaning up the damage or debris all over town. Other places tornadoes have touched down resonantly are Virginia and North Carolina the worst one was the one in Carolina taking three lives. To not be one of those three you must find shelter once you hear the word "WARNING." if you hear "watch" then prepare to go into "WARNING." Pleas remember that.

A tornado is a violently rotating column of air that spins while in contact with both the surface of the Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. This is what hit a little town called Greensburg Kansas, no bigger than 785 people. The tornado ripped through the town like a child goes through their present on Christmas morning. From this day on Greensburg will never be the same, dreams and hopes scattered everywhere. But, Greensburg came back and hit the tornado back by trying to become the “Greenest Town in America”.

The yearly average number of thunderstorm occurs in parts of Colorado and New Mexico are powerful and less noted Thunderstorms in the US even though there are up to 70 thunderstorms a year. Solar heating is one requirement for thunderstorm formation yes, but another extremely important requirement is warm moist air. The Gulf of Mexico supplies areas with moist tropical air masses. These air masses are almost always unstable, so are quickly able to form into cumulonimbus clouds as the surface these areas Eastern Colorado and Northeastern New Mexico of are pretty much made of mountainous terrain. With mountain slopes in these areas that face the sun absorb more solar radiation and become a lot warmer creating strong updrafts that form into cumulus

Lightning is basically a large amount of static electricity. An individual can create a small amount of “lightning” by rubbing a balloon with carpet which produces a relatively small amount of static electricity. Lightning is formed when charged particles in a cloud become polarized and separate significantly with positive charges moving up and negative charges moving

Powerful thunderstorms ran through California on Monday. The storms briefly knocked out the power to the Los Angeles’ airport and walloped the Sierra Nevada with blizzard conditions. Roads were flooded with over a foot of water in San Francisco Bay Area. Some counties saw about 11 inches of rain over 72 hours. Whiteout conditions are warned in Sierra Nevada by forecasters; 2 inches of snow was falling per hour. Sugar Bowl ski resort near Lake Tahoe saw 33 inches of snow overnight.

When a thunder storm passes overhead strong negative charges attract positive charges from the ground. The positive charges in the ground will move towards and up the tallest things in the area wether that be trees or telephone poles. Negative charges will "branch" down towards the positive charges and the first negative charge to get close to the ground a positive charge will fly into the negative charge when these two charges finally connect they create a lightning stream. It's called a thunderstorm for a reason so let's now talk about thunder.

Potential connections exist between total lightning and mesovortex formation, which is the parent circulation from which QLCS tornadoes are born. Many studies have found that mesovortexgenesis is initiated at low levels by tilting, in downdrafts, of crosswise baroclinic horizontal vorticity (Trapp and Weisman 2003 Part II, Wheatley and Trapp 2008, Atkins and St. Laurent 2009 Part II). Additional studies have found that strong low-level updraft is critical in converging and amplifying vertical vorticity associated with the mesovortex (Schenkman et al. 2012, Atkins and St. Laurent 2009). Trapp and Weisman (2003 Part I) also found that the amount of wind shear had large implications on mesovortexgenesis. As wind shear increased in both magnitude and

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.

The thunderstorms with rains begin to move slowly with mild western winds (too much winds will disperse the buildup). In a day or two, stronger vertical currents build up over the ocean surface upward. More warm air rises and the winds begin to move in circular manner, caused by the

Nebraskans are no strangers to tornadoes. They are a part of the spring and summer living in the Central Plains. We all know the damage tornadoes can create either first hand, as some can remember being around for the 1980 tornadoes that ripped through Grand Island, or know someone who has experienced a tornado first hand. Even though I have been living in Nebraska my entire life I still do not understand exactly how a tornado forms or what ingredients are needed in order to make a tornado form. In this paper that is exactly what we will look at, how a tornado is formed. We will look at the conditions needed for tornado formation, how tornadoes are formed out of supercells, and finally what spotters look for when chasing

“Having irregularities like that in the terrain can help generate wind patterns and heating or cooling patterns that would boost the likelihood of thunderstorms.”

How do tornadoes form? Most tornadoes form from thunderstorms. When tornadoes form it gathers moist air from Gulf of Mexico and cool, dry air from Canada when these two types of air masses meet it creates a weakness in the Earth's atmosphere. This causes a change in wind direction and increase in speed and a rising in height. This creates an invisible destructive mass of air, It also creates a parallel twisting effect in the lower part of the earth's atmosphere. And lifting air inside the updraft tilts the rotation of the air to horizontal. This will create and deadly strong mass of wind.
