Scientists begin to unravel summer jet stream mystery As the UK's official weather service the Met Office works closely with the media to ensure that the country is aware of, and can cope during, times of extreme weather. The Met Office Press Office provides journalists with accurate and reliable weather and climate information and resources for stories on TV and radio, in print, and online. Welcome to the Press Office, the Met Office's dedicated resource for journalists. The Press Office works closely with the UK's media to provide journalists with accurate and reliable weather and climate information and resources to support the nations enduring fascination with the weather. Here on the Press Office web pages you can find our latest news releases, news archive and the official blog of the Met Office press office.

De 27 skytyper: DMI Skybeskrivelserne her giver et lille indblik i denne uendelige variation, men er samtidig ordnet strengt efter de 27 forskellige meteorologiske skytyper hver for sig med et så godt som muligt repræsentativt dansk skybillede, beskrevet i sammenhæng med den vejrsituation skyen er opstået i. Desuden vises skysymbolet. Billederne er alle sammen originale optagelser optaget, på nær få undtagelser, i perioden 2007-2008 henover året på Sydsjælland af Robert Hinnerskov. Udgangspunktet er at vise, hvad man kan se på himlen set i sammenhæng med skiftende vejrsituationer, årstider og fremherskende vejrsystemer. Vi er faktisk smadderheldige, for Danmark ligger nemlig et unikt sted på kloden hvor det meste vejr og de fleste luftmasser passerer forbi året igennem. CL1 Cumulus humilis, smuktvejrscumulus med ringe vertikal udstrækning. En dag med vestenvind, hvor en højtryksryg passerer området. CL2 Cumulus congestus, staksky med moderat eller stor vertikal udstrækning. CL5 Stratocumulus, bølget lagsky.
Drought, Fire, Floods Climate change is intensifying the circulation of water on, above and below the surface of the Earth — causing drought and floods to be more frequent, severe and widespread. Higher temperatures increase the amount of moisture that evaporates from land and water, leading to drought in many areas. Lands affected by drought are more vulnerable to flooding once rain falls. As temperatures rise globally, droughts will become more frequent and more severe, with potentially devastating consequences for agriculture, water supply and human health. Hot temperatures and dry conditions also increase the likelihood of forest fires. earth :: a global map of wind, weather, and ocean conditions
Wind Map An invisible, ancient source of energy surrounds us—energy that powered the first explorations of the world, and that may be a key to the future. This map shows you the delicate tracery of wind flowing over the US. The wind map is a personal art project, not associated with any company. We've done our best to make this as accurate as possible, but can't make any guarantees about the correctness of the data or our software. Please do not use the map or its data to fly a plane, sail a boat, or fight wildfires :-) If the map is missing or seems slow, we recommend the latest Chrome browser. Surface wind data comes from the National Digital Forecast Database. If you're looking for a weather map, or just want more detail on the weather today, see these more traditional maps of temperature and wind.
eGFI – Student Blog » Turning Air into Water Posted on December 23rd, 2011 by axb In a world increasingly affected by climate change, unexpected droughts are a harsh reality for many farmers whose livelihoods depend on regular rainfall. That’s why Edward Linacre, an industrial design graduate student from Swinburne University of Technology in Australia, decided to invent a device that can literally harvest water from thin air. Airdrop, as it’s called, recently won the prestigious James Dyson Award, which grants Linacre over $14,000 to develop the product. The sleek, minimal design of Airdrop is in part inspired by the extraordinary water-gathering abilities of the Namib Desert Beetle, which survives in very arid climates by collecting moisture from the air with its wings. Watch Linacre explain his ingenious invention in this video: Airdrop is purposely designed to be an inexpensive, low-tech solution to drought that farmers can easily install and maintain.

Flights probe jet stream role in floods A major international effort is under way to research one of the greatest unknowns in weather forecasting - the influence of the jet stream. For the first time, a fleet of drones and planes is being deployed from the United States, Iceland and Britain to investigate the flow of air crossing the Atlantic. Jet streams are powerful currents of high-altitude wind that govern the patterns of weather down on the surface. The one over the Atlantic has frequently driven storms over Britain, most recently last winter, causing devastating floods. Early results indicate that the jet stream is narrower, stronger and more sharply defined than predicted by computer models - which could have implications for weather forecasts. Although forecasting has improved massively in recent years, a particular kind of disturbance in the jet stream over America is blamed for about 100 late or inaccurate forecasts of extreme rainfall over Europe in the past decade.

Dust Over the Arabian Sea October is a month of transition for weather patterns over the Arabian Sea. In the summer, winds blow from the sea toward land. In the winter, the winds reverse and blow over the Arabian Sea from the northeast. During October, between the summer and winter monsoons, the prevailing wind direction varies. When the Visible Infrared Imaging Radiometer Suite (VIIRS) on Suomi NPP satellite acquired this image on October 26, 2016, northeasterly winds were dominant and blew several dust plumes off the coast of Iran and Pakistan.

Here's a whole year's worth of weather in one video We all know that 2015 was the hottest year on record. But what did that look like exactly? Thanks to all the handy satellites stationed around Earth we now have the ability to watch our weather 24/7 from space. And that also gives us the chance to take a broader perspective and look back on the year that was, thanks to this beautiful time-lapse from weather monitoring organisation EUMETSTAT. The whole video goes for more than 8 minutes, which sounds a long time. We start with a snowy Northern Hemisphere and scorching hot Southern Hemisphere, divided by a whole lot of pretty swirly clouds forming towards the equator. In March, the Sun starts to move very slowly towards the north, defrosting things along the way. By the time May rolls around, things are getting a lot cloudier all over the planet, due to the warming land mass up north.
