Naked science lightning

Globally, there are more than thunderstorms occurring at any moment, odia nacket video lightning striking the Earth below about times every second. Lightning strikes also cause fires; half of the wildfires reported in the US are attributed to lightning strikes, and every year there are human victims.


The Berkeley team reached their conclusions by naked data from a large network of sensors across the US mainland which can pick up radio pulses produced by lightning strikes. This strike data was then matched up with temperature and precipitation measurements for each place. Higher temperatures mean more convective power, while water-saturated air supplies the ice crystals - or hydrometeors - that rub together to "charge up" thunder clouds.

The product of the two, the researchers found, is strongly correlated with lightning frequency. This means that temperature changes anticipated through the effects of climate change are likely to increase science overall strike frequency.

A further complexity is youngserbianpussy lightning itself modifies the atmosphere, producing oxides of nitrogen.

These are themselves greenhouse gases, which are likely to accelerate the lightning yet further. Podcast MP3 Oggcast Vorbis.
