Photo Details at the End Reveals What Causes Lightning

As a result Dwyer and his team turned to Low Frequency Array (LOFAR), a group of thousands of small telescopes in the Netherlands. LOFAR regularly observes distant galaxies and exploding stars. But according to Dwyer, “it also happens to be effective in measuring lightning.”

When a hurricane hits, there is no practical space for LOFAR to do. So instead, the telescope looks at its antennae to detect a million or more radio waves emanating from lightning. In contrast to visible light, radio can pass through thick clouds.

Using radio transmitters to make lightning maps is not uncommon; purpose-built radio antennas are a long-running storm in New Mexico. But the images are low or in only two dimensions. LOFAR, a state-of-the-art telescope, is capable of measuring mapping by a meter-by-meter measure in three measurements, and it is 200 times faster than the previous weapons could have found. “LOFAR standards give us an accurate picture of what is happening in the midst of a hurricane,” Dwyer said.

Lightning strikes make up millions of radios. In order to recreate the 3D lightning image from data distortions, the researchers used a method similar to that used in the Apollo lunar eclipse. Algorithms are constantly updated to determine the location of an object. When a single radio anchor only shows where the flash is going, adding the output from the second anchor changes the location. Slowly moving through the thousands of LOFAR antennas, the algorithm generates a clear map.

When the researchers analyzed what happened in August 2018, they found that all the radios came from a distance of 70 meters inside a cloud cloud. Quickly he thought that the shape of the pulse contributes to one of the two preconceived notions of how the known lightning strikes.

One idea admits that light from the atmosphere — the atmosphere — collides with electrons inside thunderstorms, triggering strong electromagnetic waves that propel electric fields.

New features show opponents of doctrine. It starts with ice clusters within the cloud. The strong collision between the needle-like crystals removes some of the electrons, leaving one part of the ice crystal strong and the other flawed. The positive end attracts electrons from nearby air molecules. More and more electrons enter from distant gas molecules, forming ribs of carbon dioxide that emanate from each tip of the ice. These are called streamers.

Each tip of the crystal produces a series of streams, with individual streams flowing in a constant flow. These rivers heat the air around them, tearing electrons out of the air molecules in large quantities so that more water flows through the glacier. Eventually, the river becomes hot and fast enough to become a leader — a process of lightning fast.

“This is what we see,” he said Christopher Stepka, the first author of a new paper. In the video showing the onset of the flash that researchers made from the data, the radios grow exponentially, probably due to the overflow of the streamers. “When the flood stops, we see a lightning bolt nearby,” he said. In recent months, Sterpka has been producing lightning films that look similar to the original ones.
