The Weird Cloud Atlas
*Full story: http://www.rexfeatures.com/nanolink/hscd Supercell thunderstorms rotate with immense energy, causing a strong updraft and severe weather, including tornadoes, hail, heavy rain, lightning and heavy winds. Inside these severe long-lived storms within the wind speed and direction changes with height. This produces a strong rotating updraft of warm air (a mesocyclone) as well as a separate downdraft of cold air. Around a third of supercells produce tornadoes and are termed tornadic. If your knowledge of clouds only extends to ‘dull and grey’ or ‘white and fluffy’, then prepare to be amazed by this cloud atlas. Nature also produces clouds in all shapes, sizes and colours. Some can fool the unwary into thinking they’re having a UFO experience; others send folks rushing into storm shelters.
