Understanding Lightning: Continuing Current/Hot Lightning
Flashes which contain both return strokes and continuing current are also common. These flashes will flicker, leaders/return strokes, and also have short periods of constant illumination, continuing current.
Thunder starts as a shockwave from the explosively expanding lightning channel when a large current causes rapid heating. However, it is possible that you might see lightning and not hear the thunder because it was too far away. Sometimes this is called “heat lightning” because it occurs most often in the summer.
A related term, heat lightning, is any lightning (IC or CG) or lightning-induced illumination that is too far away for the thunder to be heard. It may have reddish (“heat”) color, like sunsets, because of scattering of blue light.
A: Swimming during a thunderstorm is one of the most dangerous things you can do. Lightning regularly strikes water, and since water conducts electricity, a nearby lightning strike could kill or injure you. … To be really safe, you should not swim in an indoor pool when lightning is around.
Other than distance from an observer, there is no difference between the two. “Heat lightning” is lightning generated by a thunderstorm so distant that its light has outrun the much slower moving and more easily disrupted sound waves from the storm. … The fact is, all lightning produces thunder.
The high humidity, in conjunction with warm temperatures, creates massive amounts of warm, moist air rising into the atmosphere, where it can easily form a thunderstorm. … As the process of evaporation and condensation occurs, these droplets collide with other moisture that is condensing as it rises.
Even though your home is a safe shelter during a lightning storm, you may still be at risk. About one-third of lightning-strike injuries occur indoors. Here are some tips to keep safe and reduce your risk of being struck by lightning while indoors.
Don’t stand near a window to watch the lightning. An inside room is generally safe, but a home equipped with a professionally installed lightning protection system is the safest shelter available.
If you are close enough to a storm to hear thunder, you are close enough to be struck by lightning. Always head indoors when you hear thunder. After seeking shelter from a storm, you should stay indoors until the storm has passed and you can no longer hear thunder. No place outside provides safe shelter from a storm.
Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds.
The lightning you see is the discharge of electricity that travels between clouds or to the ground. … If you’re really close to the lightning, you will see it and hear the thunder simultaneously. But when it’s far away, you see and hear the event at different times. That’s because light travels much faster than sound.
Yellow or orange lightning occurs when there is a large concentration of dust in the air. White lightning is a sign of low humidity or a little amount of moisture in the air. White is the color of lightning that most often ignites forest fires.
The safest location during a thunderstorm is inside a large enclosed structure with plumbing and electrical wiring. These include shopping centers, schools, office buildings, and private residences.
Because lightning tends to hit tall objects, trees are likely targets. They’re especially prone to lightning strikes because electricity seeks the path of least resistance, and the sap and moisture inside a tree make it a better conductor than the surrounding air.
There is not an increased chance of getting hit by lightning if you are near a window. … Also glass is not a conductor so being struck by lightning through the window would take the glass being shattered first and then you could be struck by lightning but this would require two strikes.
It’s unsafe to shower during a thunderstorm. If lightning strikes a water pipe or nearby ground, the electricity can travel through the plumbing. This could potentially cause electrocution if you’re showering or using water. Your chances of getting electrocuted by lightning are low.
Lightning can also travel through any metal wires or bars in concrete walls or flooring.” So it sounds plausible that it could happen to you. But according to Aquatic Safety Research Group, “There are no documented reports of fatal lightning strikes at indoor swimming pools. None!
