A bolt from the blue can strike ground at a spot with “blue sky” above it. Storms which produce mostly negative CGs tend to produce CGs earlier in the storm lifecycle and produce significantly more CGs than similar storms which instead produce mostly positive CGs.Ī “bolt from the blue” is a CG which starts inside a cloud, goes out the side of the storm, then travels horizontally away from the cloud before going to ground. Some storms produce more positive than negative CGs because of the charge distribution in the storms, but+CG dominated storms are not as common. +CG flashes typically have only a single return stroke, and they are more likely than -CGs to have a sustained current flow. Less commonly, a downward traveling positive leader followed by an upward return stroke will lower positive charge to earth, referred to as a positive CG (or +CG). The net effect of this flash is to lower negative charge from the cloud to the ground so it is commonly referred to as a negative CG (or -CG). The more common cloud-to-ground flash has a negative stepped leader that travels downward through the cloud, followed by an upward traveling return stroke. The actual diameter of the lightning channel current is one to two inches, surrounded by a region of charged particles. We see lightning flicker when the process rapidly repeats itself several times along the same path. A negative CG flash consists of one or perhaps as many as 20 return strokes. This return stroke current of bright luminosity travels about 60,000 miles per second back towards the cloud. When the oppositely-charged leader and streamer connect, a powerful electrical current begins flowing. As it nears the ground, the negatively charged stepped leader causes streamer channels of positive charge to reach upward, normally from taller objects in the area, such as a tree, house, or telephone pole. This stepped leader is invisible to the human eye, and shoots to the ground in less time than it takes to blink. In the most common type of cloud-to-ground lightning (CG), a channel of negative charge, called a stepped leader, will zigzag downward in roughly 50-yard segments in a forked pattern. If the plane is below the cloud, then a CG flash could result. Lightning can also be triggered by aircraft flying through strong electric fields. Upward triggered lightning usually occurs in response to a natural lightning flash, but on rare occasions can be “self-triggered”-usually in winter storms with strong winds. Triggered lightning starts at the “ground,” which in this case may mean the top of a tower, and travels upward into the cloud, while “natural” lightning starts in the cloud and travels to ground. Artificially initiated lightning is associated with things like very tall structures, rockets and towers. None of the Season 4 challenges actually end until July 9, though, so you’ll still have plenty of time to earn those Battle Stars once the initial frenzy dies down.Charge distribution in a typical storm cloudĭoes lightning go up or down? There are two ways that flashes can strike ground: naturally downward (those that occur because of normal electrification in the environment), and artificially initiated or triggered upward. Right now, all the best players are probably rushing to collect their Week 4 rewards, meaning that the center of the storm is a particularly dangerous place to be. Having a teammate to watch your back and potentially revive you will make this challenge a lot easier.įinally, if all else fails, you may want to hold off an this challenge for a few days or even a week. If you usually play in Solo mode you may also want to consider trying Duos or Squads. Once the next storm circle arrives, carefully make your way to the center. Try to stick to the outskirts while collecting weapons and materials in case you do run into an opponent. You’ll want to stay away from popular spots on the map to avoid confrontation as much as possible, since dying will force you to start over entirely. If you stall for longer enough the first storm circle will appear while you’re still in the air, making it easy to quickly float down and collect your first purple lightning bolt.įrom here, things get a little more difficult. Wait until the last possible second and then immediately activate your glider. To start, take your time getting off the bus at the start of each match.
