11. Arctic and Antarctic Storms: Polar Blue Flashes
Although polar areas are less likely to get thunderstorms, when they do arise they can provide some of the most striking displays of blue lightning. The very dry and frigid air typical of Arctic and Antarctic settings provide perfect circumstances for blue lightning to be seen. Thunderstorms are growing more often in these polar areas as global climate patterns change, thereby providing more chances to see this event. Usually connected with convective activity over rather warmer open water areas, like leads in sea ice, the blue lightning in polar storms is linked. The blue flashes against the white snow and ice produce an amazing and lovely show. Particularly interested in how the shifting temperature might be influencing the frequency and severity of polar lightning are scientists examining these phenomena. In some of the most sensitive climate zones on Earth, the occurrence of blue lightning not only offers an amazing visual spectacle but also acts as a clue of atmospheric changes.
12. Mesoscale Convective Complexes: Vast Blue Light Shows
Large, ordered thunderstorm systems called mesoscale convective complexes (MCCs) can create broad displays of blue lightning. Usually forming in the warm season in the mid-latitudes, these storm systems could span regions more than 100,000 square kilometres. MCCs’ great scope and length provide perfect environment for blue lightning to be produced. Many times, as these systems change, they produce a sizable, cold cloud barrier high above. Comprising mostly of ice crystals, the top parts of these clouds offer a perfect forum for charge separation and lightning generation. At these high altitudes, the dry air lets the blue wavelengths of lightning travel enormous distances free from major scattering. Ground-based observers might see a vast canopy of blue flashes lighting the night sky, occasionally visible hundreds of miles distant. By use of the presence and dispersion of blue lightning, meteorologists investigating MCCs indicate the structural and intensity of the system, therefore enhancing forecasts and knowledge of these large-scale storm complexes.
