All liquids always contain gases in a greater or lesser concentration depending on the pressure and temperature to which it is subjected. These gases almost always end up as more or less small bubbles on the surface of the liquid. When these bubbles explode, especially if they are microscopic, minuscule drops are expelled at great velocity, and the drops almost instantly travel notable distances from the surface of the liquid that they came from.
President Donald Trump on Wednesday proposed Barry Myers as the next administrator of the National Oceanic and Atmospheric Administration (NOAA), an agency whose budget the administration has proposed slashing for fiscal year 2018. (From EOS / By Randy Showstack) -- Myers, who is chief executive officer of AccuWeather, Inc., would be just the second nonscientist nominated to lead NOAA [...]

The appointment of Myers, a businessman and [...]
If current carbon emissions and climate trends hold, the Far North can join the hurricane-soaked South as a place of wet-weather extremes, new research shows. Climate warming is likely to bring more episodes of heavy rain, above-freezing winter thaws and scorching hot summer days in the coming decades, says a study by scientists at the University of Alaska Fairbanks. By the end of the century, one-day maximum rainfalls will be 53 percent heavier than what is now considered the norm — the weather recorded from 1981 to 2010 — and maximum five-day rainfalls will be 50 percent heavier, according to the study.
Mixing artificial intelligence with climate science helps researchers to identify previously unknown atmospheric processes and rank climate models. As Earth-observing satellites become more plentiful and climate models more powerful, researchers who study global warming are facing a deluge of data. Some are now turning to the latest trend in artificial intelligence (AI) to help trawl through all the information, in the hope of discovering new climate patterns and improving forecasts.

Filling this position [...]
Controls engineers at UC San Diego have developed practical strategies for building and coordinating scores of sensor-laden balloons within hurricanes. Using onboard GPS and cellphone-grade sensors, each drifting balloon becomes part of a "swarm'' of robotic vehicles, which can periodically report, via satellite uplink, their position, the local temperature, pressure, humidity and wind velocity. This new, comparatively low-cost sensing strategy promises to provide much-needed in situ sampling of environmental conditions for a longer range of time and from many vantage points within developing hurricanes.
Using a new theory, Erwin Lambert shows that more freshwater in the Arctic may strengthen the Gulfstream's extension into the polar regions -- the opposite of what has generally been anticipated with future climate change .A new study from researchers at the Bjerknes Centre for Climate Research gives less reason to fear a weakening of the Gulfstream due to climate change. One of the suggested 'tipping points' in the climate system is a substantial slow-down or even collapse of the Gulfstream due to increased freshwater input in the northern seas.
It doesn't matter where you get your weather forecast. With the newest weather satellite in orbit, prediction models will probably improve overnight. The GOES-R satellite was launched from Cape Canaveral on Saturday afternoon atop an Atlas V 541 rocket. It's the first of three satellites being built to replace the aging United States weather satellite system.
Seismologists in Japan have tracked, for the first time, a particular type of tiny vibration that wobbled through the Earth from the Atlantic seafloor. It was started by a "weather bomb": the same low-pressure storm, off Greenland, which made UK headlines in late 2014.
Panasonic – yes, the electronics company – says it has developed a weather model that doesn't just compete with the GFS and Euro, it has actually outperformed both in some instances.
(Click to enlarge) For reasons not completely understood, in some years the anti-cyclone is less powerful than normal. The weaker winds it produces fail to draw cold waters up to the ocean's surface, thus opening the way for warm, nutrient-poor tropical waters. These changes in water temperature and climatic conditions are known as "El [...]
