What is storms: Definition and 33 Discussions

A storm is any disturbed state of the natural environment or the atmosphere of an astronomical body. It may be marked by significant disruptions to normal conditions such as strong wind, tornadoes, hail, thunder and lightning (a thunderstorm), heavy precipitation (snowstorm, rainstorm), heavy freezing rain (ice storm), strong winds (tropical cyclone, windstorm), wind transporting some substance through the atmosphere such as in a dust storm, among other forms of severe weather.
Storms have the potential to harm lives and property via storm surge, heavy rain or snow causing flooding or road impassibility, lightning, wildfires, and vertical and horizontal wind shear. Systems with significant rainfall and duration help alleviate drought in places they move through. Heavy snowfall can allow special recreational activities to take place which would not be possible otherwise, such as skiing and snowmobiling.
The English word comes from Proto-Germanic *sturmaz meaning "noise, tumult".Storms are created when a center of low pressure develops with the system of high pressure surrounding it. This combination of opposing forces can create winds and result in the formation of storm clouds such as cumulonimbus. Small localized areas of low pressure can form from hot air rising off hot ground, resulting in smaller disturbances such as dust devils and whirlwinds.

    The Probability of Rain: A Meteorologist's Perspective.

    I searched, "is infinity possible?" Because I was coming up with some thoughts which seemed logical (I hope) so I was compelled to find others discussing the topic to see if I even came close to several different answers.

    B Protecting Your Computer from Solar Storms - Is a Faraday Cage Enough?

    How did you find PF?: Via Google search From what I understand in scientific publications, if there is a strong solar storm directed towards the Earth, the effects would be such that any electronic equipment would suffer irreparable damage. I ask, if I put my computer inside a Faraday cage...

    Can Storm Chasing be Considered a Form of Nature Appreciation?

    When we hear the word storm, we think of the threats that it brings and the damage it might leave behind. I like this video, because it shows the spectacular sky shows that come with storms. They are surely one of our most magnificent displays of nature.

    B Can Star Wars-like asteroid storms exist?

    I know, in our solar system, the asteroid belt is very rare, and the rings of Saturn is thin. But can dense asteroid clouds exist elsewhere? For example in a binary star system, where constant changing of gravity prevent the forming of a planet from chunks?

    What is the impact of storms on submarines?

    Here is a scenario to further explain. Let's say I am traveling inside of a submarine. I travel within a depth of 100 to 600 feet deep or 4 to 19 atmospheres. How would I and my submarine be affected if there were a hurricane, tsunami, or hurricane above the ocean. Furthermore, does the...

    The impact of desertification and dust storms on agriculture

    B Mars' Global Sandstorm: Causes and Effects

    Recently I read a book about Mars, and it says that global sandstorm blows from southern hemisphere to northern hemisphere at perihelion. It's because the southern part is more heated at that position and the closer distance to sun gives it a high temperature, thus sublimating large amount CO2...

    What is the mass of Jupiter's white oval storms compared to Earth?

    I know the Great Red Spot on Jupiter is much larger than the white ovals. However I'm curious as to how much mass the white oval storms would have compared to say the Earth. I know they're ovals and from what I've seen they're about 9,000 km long and 5,000 km wide which if I paid attention means...

    Can hail cannons really disrupt hail storms?

    There is an episode of 'The Magic of Science' on the Discovery Channel that features a device called a hail cannon which uses the force of a vortex of air blasted out of a tube by an oxygen-acetylene explosion to move objects and it was mentioned by a cast member of the show that this device can...

    Windy Weather on the Plains: When Storms Get Named

    A tropical storm is named if a storm has winds that exceed 39 MPH and it makes news. 39 MPH winds are really common here on the plains. We routinely have storms here with sustained winds of 60-70 MPH, but they don't get named and they don't make the news. Right now we have a storm with...
