Ocean currents… (‘Perpetual Ocean’ by NASA) *****Fohn winds / Foen winds:Antarctica's troublesome 'hairdryer winds' Image copyright BAS It's an ill wind that blows no good - at least not for the ice shelves on the eastern side of the Antarctic Peninsula.
A new study has found an atmospheric melting phenomenon in the region to be far more prevalent than anyone had realised. This is the foehn winds that drop over the big mountains of the peninsula, raising the temperature of the air on the leeward side well above freezing. "The best way to consider these winds is how they translate to german now, which is 'hairdryer' ('Foen')," explained Jenny Turton from the British Antarctic Survey (BAS).
"So, they're warm and they're dry and they're downslope. Deck.gl Blog. A few weeks ago I set on trying out new WebGL 2.0 features with deck.gl.
WebGL 2.0 brings plenty of new goodies to be used for game development, creative coding and data visualization like instancing, floating-point textures, transform feedback, multiple render targets, and more. With this in mind, and inspired by the work of Cameron Beccario, Viegas and Wattenberg, and NASA, I created a WebGL 2.0 wind map demo using deck.gl. □ This stunning #satellite image shows dust that has spread from W Africa to the two closest islands (Fuerteventura and Lanzarote) □ *****Atmospheric pressure: The fascinating and terrible things that would happen to you if you tried to fly on Jupiter — and other planets. Saharan dust causing hazy conditions. Reports of haziness over the weekend are the result of high winds which carry over mineral dust from the Saharan Desert, bringing with it hazy visibility and for some, respiratory problems.
Meteorologist Jean-Marc Rampersad said to LoopTT that, although it is difficult to predict how long these conditions will last, if strong winds continue, chances are likely that the present hazy conditions will persist for up to 48 hours. *****Coriolis Force: Water vapour satellite imagery □️ is essential in forecasting how #cloud and #rain develops, and sometimes it can look absolutely amazing! □Here is a stunning satellite image from yesterday of a low pressure system, but can you guess #WhereOnEarthIsThis? □ The effect of differential heating of the land and ocean - western coast of the Yucatan Peninsula, from 30000 ft.

Cold, dense air pouring through gaps in the Dinaric Alps causes the brutal Bora wind. Scientists say the global ocean circulation may be more vulnerable to shutdown than we thought. The Gulf Stream carries warm water from the eastern coastline of the United States to regions of the North Atlantic Ocean.
(NASA’s Goddard Space Flight Center) Intense future climate change could have a far different impact on the world than current models predict, suggests a thought-provoking new study just out in the journal Science Advances. If atmospheric carbon dioxide concentrations were to double in the future, it finds, a major ocean current — one that helps regulate climate and weather patterns all over the world — could collapse. And that could paint a very different picture of the future than what we’ve assumed so far. The Atlantic meridional overturning circulation, or AMOC, is often described as a large oceanic conveyor belt.

WeatherCast - Weather Word Wednesday and today's word is... Foehn effect. When air passes over mountains, the valleys on the downwind side (or 'lee' side) commonly experience strong and gusty downslope winds accompanied by abrupt warming and drying.
These are known as foehn winds, and their warming and drying effect - the foehn effect - can be striking and far-reaching. What is the foehn effect? Foehn winds (sometimes written "Föhn") are common in mountainous regions, regularly impacting the lives of their residents and influencing weather conditions for hundreds of kilometres downwind.

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.
