Parts of southern Africa have been devastated by Cyclone Idai over the last week. The tropical storm has been described as the worst weather-related disaster to hit the southern hemisphere, with over 2 million people affected by extreme widespread flooding.
The Midwest has been hit by extreme freezing conditions this week. Parts of the Midwest will experience the coldest temperatures in over 20 years. A polar vortex which is causing extreme Arctic blasts could bring temperatures as low as -53°C.
Parts of Europe have been experiencing the worst snowfall in decades. There has been record-breaking snowfall in January in some parts of the Alps and hazardous conditions have led to dozens of fatalities across the continent.
Parts of Australia have been affected by a heatwave since the end of December 2018. Tarcoola in South Australia reached temperatures exceeding 49°C this week. The top 15 hottest places in the world on the 15th of January were all in Australia, as the record-breaking hot weather continues to affect the country.
The WMO has announced that there is a high probability of an El Niño event in early 2019. Although the event has not been forecasted to be as strong as the 2016 event, El Niño is known to have a major impact on temperatures and rainfall across the globe.
The El Niño Southern Oscillation (ENSO) is a large-scale climatic phenomenon that originates in the tropical Pacific but affects global climate patterns. The warm phase is known as El Niño and the cold phase is La Niña. El Niño occurs irregularly every two to seven years and peaks around in winter.
The Royal Meteorological Society is hosting an extreme weather conference to explore the severe weather events and climates around the world. Whether it's tornadoes or hurricanes, working in extreme conditions or communicating high impact weather, we'll take a closer look at extreme weather - its power, its beauty, its occasional absurdity and its fragility in the face of human activity.
In late May, forecasters at the National Oceanic and Atmospheric Administration (NOAA) predicted that the 2018 hurricane season would be average or slightly above average. Specifically, the forecast had a 70% chance of between five and nine hurricanes, with a total of 10 to 16 named storms.
On the 7th of September 2018 a tropical storm formed near the Marshall Islands in the Pacific Ocean moving north west. First referred to as Tropical Depression 26W, it strengthened into a typhoon soon after. The Japan Meteorological Agency named it Mangkhut. NASA’s Aqua satellite captured Typhoon Mangkhut lashing Guam and the Northern Marinas Islands on 10 September (UTC).
