![]() Along with the danger of lightning itself there is also the wildfire risk that accompanies the types of storms that can produce it. Do pay attention to dry lightning however. Don’t be alarmed by heat lightning at night, chances are if you can’t hear the thunder then the storms are too far away to directly impact you. The term will just differentiate how it is perceived by you. ![]() So there is no different types of lightning, heat or dry it is still lightning. These wind gusts have the potential to rapidly spread a wildfire that may be started by the lightning. Another issue that can increase the fire danger is the wind gusts that can develop due to the rain evaporating before reaching the ground. Lightning without the the rain poses a fire threat and, when forecast, are often accompanied by fire weather watches or red flag warnings. Dry thunderstorms are more common in arid climates that you would find out west in the Mountains or other arid climates. The lightning strike did create thunder but it can only be heard by those closer to the storm. This means you get the lightning, you hear the thunder, but you get little to no rain at the surface. Given the right conditions it is possible for clouds to form, a change to develop with the ice and water colliding inside the could to make it a thunderstorm, but the rain will evaporate in the dry air below the storm. The different senses of the word heat can be confusing to novices. However, as a noun, heat has a different sense, that of energy entering or leaving a system due to temperature gradients. Unlike heat lightning you see the flash, hear the thunder, the only thing you don’t get is the rain. begingroup Pedantic, but semantically better: use thermal energy rather than heat energy. Light may have no trouble traveling that far but the sound cannot.ĭry lightning is a little more straight forward. What is interesting that given the right circumstances light may be able to travel close to 100 miles from the storm to you the viewer, although 30 to 50 miles is more typical. ![]() You may easily see the lightning but sound by be reflected, refracted, or even absorbed so that there area areas that sound may not reach. The sight and sound of a thunderstorm will travel though the atmosphere but each travel at different speeds and trajectories. No there is no such thing as a lightning strike that is silent, and if you were much closer to that thunderstorm you would defiantly hear the thunder. ![]() You have just witnessed what they call heat lightning. Talk a walk on a warm summer night and you might see a distant flash but hear no thunder. Short answer: They are both lightning and no they are not different. What are they and how are they different? This phenomenon is more noticeable during the summer months when humidity levels are higher, causing the air to be hazier and enhancing the visibility of the flashes in the night sky.Heat and Dry Lightning. Heat lightning can be seen from distances of up to 100 miles, while the sound of thunder can only be heard within a range of approximately 10 miles from a lightning strike. As a result, only the light from the lightning is visible, giving the impression that it is appearing without any apparent source. This can be attributed to various factors such as hills, trees, or the curvature of the earth obstructing the view. The reason why heat lightning appears to be “out of thin air” is due to the observer’s inability to see the actual lightning bolt. In reality, heat lightning is simply the visible light produced by lightning that is too far away for the sound of thunder to be heard. Like in Orion in Winter, Burchfield found the need to expand the sky in this picture. The term “heat” in heat lightning is a misnomer, as it does not refer to temperature but rather to the misconception that hot and humid weather causes these distant flashes. Heat Lightning (also known as Landscape with Grey Clouds). It is often observed on warm summer nights and is caused by lightning produced by thunderstorms that are located far away from the observer. Heat lightning refers to a weather phenomenon where distant lightning flashes are visible without any accompanying thunder.
