The structure tells us how thunderstorms, severe and otherwise, are created, and how dangerous they may be.
Single-cell ordinary thunderstorms are short-lived storms that are common in Florida but do not produce severe weather. Although they are less common than ordinary-cell storms, multi-cell and supercell storms cause the vast majority of severe weather associated with thunderstorms.
There must be sufficient water vapor in order for the storm to form, since cloud and precipitation originates as water vapor.
Technically, lightning must be produced in order for the resulting cloud system to be called a thunderstorm. Enter your email address to follow this blog and receive notifications of new posts by email.
At the same time, a strange part of me loves storm chaser videos –the combination of crazy people and uncontrolled nature is irresistible.
Some of you might consider clicking away about now – “tornadoes don’t happen where I live”. You start with a supercell –a special storm with warm moist air rising in a huge vortex (mesocyclone) from 1 to 50 miles wide. When the now-cold air spreads out past the vortex edge, it drops back toward earth as a downdraft.
The Storm Prediction Center in Norman, Oklahoma issues a “tornado watch” when weather conditions in a specific area indicate high risk of tornadoes. Attempting to measure most things about tornadoes, such as wind speed, size, and strength, is an exercise in futility.
Tornadoes can skip or jump, making path length difficult to determine (many historical “long path” tornadoes were probably multiple vortexes or tornado families.
Since meteorologists can’t measure tornadoes, they instead rate them by damage – after all, that’s what people really care about.
Tornadoes happen almost anywhere in the world, but the United States wins hands down for severity and frequency – we have about 1200 a year ( the number is climbing recently, but this may just be better reporting).
Within the United States, nowhere is completely safe – in 2010, we had a F2 tornado in Aumsville, Oregon, about 15 miles from my house. Dixie Alley tornadoes are known for ignoring classic patterns – even though frequency is lower, severity and death rates are higher.

Supercells are incredibly rare, with significantly fewer sightings than singlecell or multicell variants, but their unique properties make them incredibly dangerous when they do occur.A supercell thunderstorm is similar to a singlecell storm and tornado in that it has a single main updraft. For example, the National Weather Service defines a severe thunderstorm as one that produces one or more of the following: wind gusts of at least 58 mph, hail at least one inch in diameter, or a tornado. Ordinary cells are a few miles in diameter and exist for less than an hour, whereas supercells are larger and can last for several hours. The severity of these storms is primarily a result of the structure of the environment in which the storms form, with plenty of energy that can be stored as heat or water vapor. When a film lacks impressive destruction footage, I’m disappointed and have to remind myself that the houses belong to real people!
It’s often rain-free under the column because everything goes up, not down (“the calm before the storm”). On the front side of the anvil cloud, the cold downdraft just brings lots of rain and hail. Multiple vortex tornadoes are several funnels simultaneously rotating around or inside a single main vortex.
Not only is it technically impossible (how do you measure overall wind speed in a rapidly moving cloud that starts anywhere?), but tornadoes change rapidly throughout their brief existence – what you measure one minute can be different a minute later. Wind gusts vary from 65 mph to over 200 miles per hour, with rare gusts measured by Doppler radar at above 300 mph.


After the tornado, experts assess damage to human-built structures and vegetation and assign a rating. Only about 6% of tornadoes are F3 or worse, and less than 0.1% are F5 (F3 = severe damage with roofs and walls torn off houses, trains overturned, strong trees uprooted, and cars lifted from the ground). Even when you look at frequency per land area, the US still gets 5 times more tornadoes than the second place winner – Australia, and 40 times more per area than other countries. Most occur in Tornado Alley (the central plains) with 50-100 tornadoes each year per state. Tornadoes occur most often in the late afternoon and evening, with the greatest number in April through June. Their tornado season is year-round, including late fall, winter, and early spring – unfortunately, this leads to public complacency.
I’ll post Part 2 later this week (it’s mostly written already, so no huge posting gaps this time!). The owner of this blog makes no representations as to the accuracy or completeness of any information on this site or found by following any link on this site. Having left my previous specialties of neurology and hospice behind for now, I am instead focused on emergency preparedness, particularly healthcare response. The supercell thunderstorm is a single-cell storm that almost always produces dangerous weather.
Although only 6 at the time, I still remember after-effects from the Palm Sunday tornadoes – my uncle’s house was neatly split in half and most houses on his street were simply missing. This warm updraft climbs until it literally hits the atmosphere, where it chills and spreads into a giant anvil shaped cloud. Although I’ll never equal a trained storm spotter, from now on, I’ll watch the sky when I visit tornado territory. Green sky and thunderstorms often go together but color doesn’t predict either tornadoes or hail. Once an actual tornado or funnel cloud  is spotted by eye or detected by radar, the local weather service issues a “tornado warning”. They probably explain occasional strange instances of sharply delineated damage – like cutting my uncle’s house in half. Sometimes, it is difficult to tell whether there was just one tornado or a multiple vertex or tornado family. Scientists downgraded wind speeds about 10 years ago, when they discovered that damage occurs at lower wind speeds than originally suspected.
The 6 point Enhanced Fujita Scale goes from F0 (light damage, like broken branches, toppled shallow trees, and chimney or sign damage) to F5 (incredible damage with frame houses lifted off foundations and carried through the air, severe damage to steel reinforced concrete, automobile sized missiles flying through the air, and debarking of trees). Real numbers might be even better than this – reporting of smaller tornadoes is probably incomplete!
The Great Plains  provide a great mixing bowl for cold air from Canada and warm air from the Gulf of Mexico, stirred together by dry air from the Rockies. For healthcare folks (and the morbidly curious), I’ll talk about types of injuries and causes of death – “need to knows” for medical response planning. The owner will not be liable for any errors or omissions in this information nor for the availability of this information.
Somehow the powers that be frequently forget that physicians will be an essential part of any response and recovery.
It is so strong that it can easily upturn cars, uproot trees and even destroy entire buildings.The main difference between a supercell storm and other types is the presence of rotational energy. Excerpts and links may be used, provided that full and clear credit is given to Sheila Sund, M.D.
For years afterwards, I preferred to hang out in basements when the sky got that “tornado weather look”. However, if this rear downdraft gets sucked back into the warm rotating updraft, not only do warm and cold air mix (bad), but they do so in a spinning pattern (really bad).


Don’t worry – I’ll still depend on official warnings, but I like the concept of personal knowledge as well. The green color results from combining red sunlight (often late in the day), heavy water content in the air (blue), and tall gray thunder clouds – but it doesn’t mean there are supercells or mesocyclones.
Modern radar can even show winds swirling into an actual tornado, although it can’t tell if the funnel has touched down yet. If you hear this, TAKE COVER IMMEDIATELY – a real tornado is occurring  Even without a tornado warning, watch for severe winds and hail – tornado weather equals severe storm weather! Tornado families are multiple tornadoes from the same supercell – they occur in quick succession in the same area. The width of the damage path indicates tornado width, and can be as small as 10 yards or over 2 miles across. Most tornadoes dissipate in under 10 minutes, but occasionally persist for an hour or more. And we’ll get into safety – what you should do before and during a storm to keep yourself and your loved ones as safe as possible. The owner will not be liable for any losses, injuries, or damages from the display or use of this information. I stick my head in everywhere to make sure we are included, and in the meantime, learn a lot about emergency response in general.
Add in relatives and cross-country road trips – most people enter tornado territory at some time. With this combination and a sprinkling of bad luck – congratulations, you’ve made a tornado! Tornado outbreaks are multiple tornadoes from one larger weather system, with tornado free gaps of no more than 6 hours. The terrain is hilly and forested, and the tornadoes are often clouded in rain, unlike the classic supercell appearance of the plains.
Some content may be disturbing to those under age 18 - parental discretion is advised.These terms and conditions of use are subject to change at anytime and without notice. This can include immense rain showers, massive two-inch-wide hail and violent tornadoes.Supercells are classified into two types, low-precipitation and high-precipitation. Exceptions are: 1) use through CreativeCommons licensing (see below) and 2) non-profit emergency preparedness organizations may print and distribute copies of posts for the purpose of community or member education. Since a typical neighborhood street is about 13 yards wide, it’s easy to see how a tornado takes out every house. Their travelling speed averages around 30 mph but they can zoom up to 70 mph or slow down to almost stationary.
Finally, population density in the south is much higher, there’s a high percentage of manufactured homes (tornado death traps), and very few storm shelters. The former supercells tend to formulate in arid climates, such as the high plains of the United States, while the latter are often found in moist climates closer to the Earth’s equator. Regardless of type, supercells form when winds coming in from various differing directions cause a rotational energy to be generated. Except for Alaska and Rhode Island, every state had at least one tornado in the last 20 years. It’s a good thing, because a strong tornado in a densely packed urban area could be catastrophic– visualize every window in every skyscraper blasted on both people inside and down below. Here, though, the supercell is depositing a huge torrent of rainfall directly through the updraft.
