SO2 and water vapour converge at Mount Nyamuragira
Sulphur dioxide (SO2) plumes can be clearly seen (coloured neon green) being emitted from the Nyamuragira volcano.
Undular Bore racing towards the Atlantic
Nightly thunderstorms in the border region of Mauritania and Senegal are at the origin of the undular bore (low-level outflow) that raced out into the Atlantic at the speed of close to 85 km/h.
Three major Saharan dust squalls
Outflow from Intertropical Convergence Zone (ITCZ) caused three major dust squalls in August 2011.
Puyehuè-Cordón Caulle Volcanic Complex
The initial ash and SO2 plume from the Puyehuè-Cordón Caulle Volcanic Complex (PCVCC) reaches South America, after circling the globe in eight days.
Large SO2 plume from the Nabro volcano, Eritrea
A large SO2 plume (red-pink colour), originating from the Nabro volcano in Eritrea, moves towards the Middle East.
Stratospheric volcanic cloud from Puyehuè-Cordón
The stratospheric volcanic cloud (ash and SO2) from the Puyehuè-Cordón Caulle Volcanic Complex (PCCVC) continues to move eastwards.
Ash and SO2 plume from the Puyehuè-Cordón
The ash and SO2 plume from the Puyehuè-Cordón Caulle Volcanic Complex (PCCVC) meanders over the Southern Atlantic.
Winter lightning with cut-off low over S Africa
Lightning over South Africa predominantly occurs during October to March over the regions that receive summer rainfall, but significant amounts of lightning may also result from winter cut-of lows (COLs) that frequently occur over the country.
