8 Things We’ve Learned Lately About Thunder and Lightning
Summer in America unofficially begins this weekend, and with it come the late afternoon and middle-of-the-night thunderstorms that are Nature’s version of shock and awe. But as common as they are, much about thunder and lightning remains a mystery. In fact, scientists are still debating what actually causes those amazing flashes across the sky.
Here are eight recent findings related to storm-watching:
1) Come to the dark side:
The dazzling thunderbolts get all the attention, but within each thunderstorm are invisible intense bursts of gamma rays, which have become known as “dark lightning.” Scientists recently discovered that the two types of lightning seemed to be connected, that there’s a gamma ray discharge immediately before a bolt shoots through the sky, although no one’s quite sure what that connection is.
The good thing about dark lightning is that it dissipates quickly so it can’t really hurt anyone on the ground. But if you should be so unlucky and fly through a thunderstorm, a release of dark lightning nearby could expose you to a significant dose of radiation. Which is just one more reason for pilots to fly around them.
2) When planes go bump in the night:
By the middle of the century, transatlantic flights could get a whole lot bumpier if a team of British scientists is right. They’re projecting that, because of climate change, the chances of encountering significant turbulence will increase by between 40 and 170 percent. Most likely, they say, the amount of airspace where nasty turbulence occurs will double. But wait, there’s more. They predict that the average strength of turbulence will also increase by 10 to 40 percent.
3) The pain in rain lies mainly in the brain:
A study published earlier this year concluded that lightning could actually trigger migraines and other headaches. The researchers asked 90 chronic migraine sufferers to document when they developed migraines during a three-to-six month period, and then tracked that data against lightning strikes within 25 miles of the migraine victims’ homes.
Their analysis found a 28 percent increased chance of a migraine and a 31 percent chance of a non-migraine headache on days when lightning struck nearby. So what’s the connection? Not absolutely clear. Some have suggested that high pressure increases the risk of migraines, while others have argued that low pressure can increase the risk. And still other research has failed to show that there even is a definite connection.
4) Hi, I’m Big Data and from now on I’ll be doing the weather:
IBM obviously is big on Big Data–it’s pretty much building its future around it–and not long ago it launched a weather analysis project it calls “Deep Thunder.” Using complex algorithms and massive computing power, the company is compiling data around the physics of the atmosphere over a number of major cities. With the resulting mathematical models, the company says it should be able to predict up to 40 hours ahead of time how much rain will fall in a particular location—with 90 percent accuracy.
