Researchers have developed an artificial intelligence system that can recognize clouds that have the potential to turn into severe storms.Their model looks at the movements of the clouds from satellite images since meteorologists cannot possibly look at all the numbers and data. This tool could help weather forecasters predict the weather better, according to industry experts."The very best forecasting incorporates as much data as possible. There’s so much to take in, as the atmosphere is infinitely complex. By using the models and the data we have [in front of us], we’re taking a snapshot of the most complete look of the atmosphere," Steve Wistar, a senior forensic meteorologist at AccuWeather said in a statement.[caption id="attachment_6953201" align="alignnone" width="1280"]

They analyzed more than 50,000 weather satellite images historically, at random. Looking for ‘comma-shaped’ clouds that are thought to lead to cyclones and lead to high winds, blizzards, etc, the researchers taught the AI tool signatures to recognize the same.Now, these computers can point out to signs of these clouds and help meteorologists focus their attention on detecting if these clouds can lead to bad weather. This method, the researchers found, can detect 99 percent of comma-shaped clouds accurately. It is also able to outperform other weather detecting methods by accurately predicting 64 percent of severe weather events.Rachel Zheng, a doctoral student in the College of Information Sciences and Technology at Penn State and the main researcher on the project said, “Because the comma-shaped cloud is a visual indicator of severe weather events, our scheme can help meteorologists forecast such events.”The findings of this study have been published in the journal IEEE Transactions on Geoscience and Remote Sensing

Careless Whispers: Scientists discover that plants can 'talk' to each other using smells

Japanese scientists have recorded a video that shows plants, in certain conditions, communicate with each other using mists that carry smells. The discovery, reveals that plants release a fine mist of airborne compounds, to warn nearby plants of potential dangers
