John Hopkinson, manager of flight operations for CHC Helicopter, said: "Inevitably, this means we will have to change our behaviours. In 1992, Russian physicist Alexandr Gurevich of the Lebedev Physical Institute in Moscow suggested that the high-energy particles produced by a cosmic ray strike ionize the air in thunderclouds, creating a region with a lot of free electrons. Typically, it would enter one of the main The goal of these settings is to come up with a balanced exposure while keeping the lightning strikes and the surrounding environment clear and detailed. On offshore installations this year there are posters in communal areas explaining the concept of triggered lightning to passengers who use the 61,000 return flights annually. It may also magnetise navigational equipment. But there's a problem: Cosmic rays with enough energy are too rare to trigger all the pulses that Gurevich and Karashtin observed. The Monmouth County fair in Freehold, New Jersey takes place in July, over 5 days, and welcomed 75,000 visitors in 2016. Being hit though can cause substantial damage, immediately prompting an emergency and then taking the helicopter out of action for maintenance and repairs. The great advantage of our lightning strike map is that thunderstorms and lightning are displayed with a very short delay. Lightning photos require a few seconds of exposure that can not be done handheld so you would need a tripod to keep the camera steady and free of any movement that would ruin the shot. Depending on the strength, the precipitation is displayed in blue (weak precipitation), green, yellow, orange (moderate precipitation), red, or purple (very heavy precipitation). The colors represent the Thus, there is danger even before the thunderstorm is in proximity. Lightning strikes often move along as the wind blows the storm clouds and it would be best to be able to capture that in one frame or at least be able to pan with the movement. However, it is important not to make your exposure time too long that the luminosity of the background would overwrite and erase the lightning strikes. "What we really need is to have these air shower arrays that measure the cosmic ray air showers going through, measure the radio waves, measure the pulses, and put it all together," he says.
