It's not a matter of duration, but a probability of occurrence. Isolated means about a 20% chance, while scattered, I believe, includes probabilities up to 50%.
An isolates storm is one that does not form near others. A severe storm is one that meets one of the following criteria: having winds of at least 58 mph,producing hail 1 inch in diameter or greater, or producing a tornado. Isolated stirms can be severe but it is fairly rare.
Scattered thunderstorms are thunderstorms in the 30-40% chance category. They are generally weak, widespread short thunderstorms that turn on and off due to a storm system moving over the area.
No, because a super cell storm is a quick and violent (and rare) storm while an isolated thunder storms are common, longer storms. Can you guys belive a 12 year old wrote this?!? It's true! ='p
occurring at irregular intervals or only in a few places; scattered or isolated
Chance of thunderstorm is 1-2%.
If it were not late at night, I would give you a better answer, but here are some definitions fromhttp://forecast.weather.gov/glossary.php.IsolatedA National Weather Service convective precipitation descriptor for a 10 percent chance of measurable precipitation (0.01 inch). Isolated is used interchangeably with few.ScatteredWhen used to describe precipitation (for example: "scattered showers") - Area coverage of convective weather affecting 30 percent to 50 percent of a forecast zone (s).NumerousA National Weather Service convective precipitation descriptor for a 60 or 70 percent chance of measurable precipitation (0.01 inch).Also, you may refer tohttp://pajk.arh.noaa.gov/Articles/articles/survey/poptext.html.When I was a forecaster, the terms had a dual meaning - current coverage as well as the amount of an area that would be covered at least at some point during a specific time period. That definition might still exist, but I need to get some sleep so this is all you get. ;-)Signed,A trained meteorologist
It comes from the Greek root Sporasmeaning scattered.
Isolated tornadoes are tornadoes that do not occur in association with an outbreak. The tornado is generally the only one produced by that weather system or one of only a few scattered ones.
Seamounts are isolated volcanic mountains scatteredacross the ocean floor
Isolated tornadoes refer to tornadoes that occur by themselves, rather than in a widespread outbreak. These tornadoes typically form from individual thunderstorms rather than from a larger weather system. They can still be dangerous and cause damage, but they are less common than tornado outbreaks.
After the storm, there was debris from the destroyed homes scattered throughout the neighborhood.
isolated means intensely in one area specifically. scattered means more disbursed across a larger area. Basically, scattered thunderstorms are generally weak, widespread short thunderstorms that turn on and off due to a storm system moving over the area. Scattered thunderstorms are thunderstorms in the 30-40% chance category.
