About Tornadoes Tornadoes form under a certain set of weather conditions in which three very different types of air come together in a certain way. Near the ground lies a layer of warm and humid air, along with strong south winds. Colder air and strong west or southwest winds lie in the upper atmosphere.

Tornado Facts and MythsA Student's Guide Tornado! Although tornadoes occur in many parts of the world, these destructive forces of nature 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.n area of rotation, 2-6 miles wide, now extends through much of the storm. Most strong and violent tornadoes form within this area of strong rotation. A lower cloud base in the center of the photograph identifies an area of rotation known as a rotating wall cloud. This area is often nearly rain-free.

Severe Weather 101 Tornado season usually refers to the time of year the U.S. sees the most tornadoes. The peak “tornado season” for the Southern Plains is during May into early June. On the Gulf coast, it is earlier during the spring. In the northern plains and upper Midwest, tornado season is in June or July. But, remember, tornadoes can happen at any time of year. Tornadoes can also happen at any time of day or night, but most tornadoes occur between 4–9 p.m. What is the difference between a Tornado WATCH and a Tornado WARNING? A Tornado WATCH is issued by the NOAA Storm Prediction Center meteorologists who watch the weather 24/7 across the entire U.S. for weather conditions that are favorable for tornadoes. A watch can cover parts of a state or several states.

How Tornadoes Form and Why Theyâre so Unpredictable The most intense tornadoes emerge from what are called supercell thunderstorms. For such a storm to form, you first need the ingredients for a regular thunderstorm, says Brooks. Those ingredients include warm moisture near the surface and relatively cold, dry air above.

- Tornadoes vary greatly in size, intensity, and appearance. Most (69%) of the tornadoes that occur each year fall into the weak category. Wind speeds are in the range of 110 mph or less. Weak tornadoes account for less than 5% of all tornado deaths.
099ea4d65fceb0ddaa4f693a66ad655e
- Tornadoes are more likely to happen in the spring and summer  because that is when the weather is generally warmest, which leads  to a more unstable atmosphere that can prod…uce thunderstorms and  thus tornadoes.

Tornado Facts and MythsA Student's Guide Thunderstorms develop in warm, moist air in advance of eastward-moving cold fronts. These thunderstorms often produce large hail, strong winds, and tornadoes. Tornadoes in the winter and early spring are often associated with strong, frontal systems that form in the Central States and move east. Occasionally, large outbreaks of tornadoes occur with this type of weather pattern.

- The National Weather Service defines a tornado as a violently rotating column of air in contact with the ground and pendant from a thunderstorm.. In other words, a thunderstorm is the first step in the creation of a tornado. Then, if other conditions are right, the thunderstorm could spin out one or more tornadoes. The three key conditions required for thunderstorms to form are: 1  Moisture in the lower to mid levels of the atmosphere. 2  Unstable air. 3  A lifting force.

Severe Weather 101 Supercells are capable of producing severe weather including high winds, large hail, and strong tornadoes. They are most frequently isolated and often develop in the warm air ahead of a squall line. A supercell also usually forms in an environment with strong vertical wind shear that causes the updraft to begin rotating.

How Tornadoes Form and Why Theyâre so Unpredictable More tornadoes are expected in the coming days. The fierce storms can happen at any time of year but are most common in May and June in North America, when atmospheric conditions tend to be most right for their formation. Tornadoes remain deadly and relatively unpredictable, despite recent advancements in weather science.

Thunderstorm Hazards - Tornadoes Wind Shear. Most tornadoes are spawned from supercell thunderstorms. Supercell thunderstorms are characterized by a persistent rotating updraft and form in environments of strong vertical wind shear. Wind shear is the change in wind speed and/or direction with height. Directional wind shear is the change in wind direction with height.

Severe Weather 101 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.

During what month does the US record the most tornadoes? May is the month with the most tornadoes The peak months for tornadoes is April, May and June. However, the most common month for tornadoes to occur is in May. May is the month with the highest frequency of tornadoes, but the most powerful tornadoes have seemed to occur a bit earlier in the year in April. April is the month when the most rare and gigantic F5 tornadoes happen. April also has the highest average number of deaths from tornadoes.

Why do tornadoes occur most often in the area known as tornado alley? No other place in the world has such ideal conditions for tornado formation. Warm moist air from the Gulf of Mexico frequently moves over the region from the south. This collides with cool air from Canada and dry air from the Rockies. This collisions of air mass is often triggers thunderstorms, often very strong ones.

Explaining the science of this spring's tornadoes What caused the tornadoes? Warm, moist air from the Gulf of Mexico moved north until it encountered cold air brought south by the jet stream. When the warm and cold air from different altitudes come together, it creates wind shear and circular air motions that lead to a tornado. The air from the south was unusually warm and moist for this time of year, according to Stu Ostro, a senior meteorologist at the Weather Channel.
