If you can predict the path of the jet stream, the upper atmosphere’s undulating river of wind, then you can predict weather – not just for a week or two, but for an entire season. A new Stanford study moves toward that level of foresight by revealing a physical link between the speed and location of the jet stream and the strength of the polar vortex, a swirl of air that usually hovers over the Arctic.
As the remnants of former tropical cyclone Beryl moved through the northern Leeward Islands and Puerto Rico, the Global Precipitation Measurement mission or GPM core satellite gathered important rainfall data on the storm.
New research found that being in a bad mood can help some people’s executive functioning, such as their ability to focus attention, manage time and prioritize tasks. The same study found that a good mood has a negative effect on it in some cases.
When NASA's Aqua satellite passed over the northwestern Atlantic Ocean, an instrument aboard looked at Tropical Storm Chris' water vapor and cloud temperatures. Appropriately, the image showed a backwards "C" or comma shaped storm. The water vapor imagery indicated Tropical Storm Chris has the potential to generate heavy rainfall.
Stronger westerly winds in the Southern Ocean could be the cause of a sudden rise in atmospheric CO2 in a period of less than 100 years about 16,000 years ago, according to a study published in Nature Communications.
Earth’s oxygen levels rose and fell more than once hundreds of millions of years before the planetwide success of the Great Oxidation Event about 2.4 billion years ago, new research from the University of Washington shows.
