A new study by MIT researchers finds that St. Elmo’s Fire could help protect airplanes from lightning strikes, reports Caroline Delbert for Popular Mechanics. The researchers found that “the special kind of electrical charge can be used to place a protective and preemptive charge around airplanes in flight, and wind affects flying versus grounded vehicles in opposite ways.”
Research affiliate Judah Cohen speaks with WGBH’s Edgar B. Herwick III about what distinguishes a Nor’easter, an extratropical cyclone powered by "strong differences in temperature," from other storms. As cold air from the Arctic meets warm water and air from the Gulf of Mexico, it creates “a very large temperature differential over a relatively short distance,” says Cohen. “And that temperature differential gives you the energy for these storms.”
In an article for CNN about the genesis of the term bomb cyclone, Brandon Miller notes how MIT researchers Fred Sanders and John Gyakum used the term to describe storms that strengthen rapidly. Miller explains that they “adjusted the ground rules to vary based on latitude. And they added the term ‘bomb’ because of the explosive power that these storms derive from rapid pressure drops.”
A study by MIT researchers finds that climate change is causing pollution to linger longer over cities and making summer thunderstorms more powerful, reports Tanya Rivero for CBS News. “We found a way to connect changes in temperature in humidity from climate change to changing summer weather patterns that we are experiencing at our latitude,” explains graduate student Charles Gertler.
Bloomberg News reporter Eric Roston writes that a new study by MIT researchers finds that climate change is making summer thunderstorms more powerful and urban pollution more potent. “Summertime weather isn’t ventilating American cities at the rate that it did in the past,” explains graduate student Charles Gertler.
MIT researchers have found that climate change could cause more thunderstorms and stagnant air in the summer, reports Martin Finucane for The Boston Globe. “With temperatures rising globally, and particularly in the Arctic, the energy in the atmosphere is being redistributed,” writes Finucane. “The result is that more energy will be available to fuel thunderstorms.”
A new study by MIT researchers shows that the Sahara desert and North Africa alternate between wet and dry conditions every 20,000 years, reports the Xinhua news agency. The researchers found that the “climatic pendulum was mainly driven by changes to the Earth's axis as the planet orbits the sun, which in turn affect the distribution of sunlight between seasons.”
A study by MIT researcher provides evidence that large-scale corn production in the U.S. impacts weather patterns, reports Eric J. Wallace for Atlas Obscura. “By increasing yields,” writes Wallace, “farmers have unintentionally created weather patterns that seem to be protecting their crops and helping them grow more corn.”
Quartz reporter Zoë Schlanger writes that a new study by MIT researchers demonstrates how climate change can negatively impact a person’s mental health. The researchers found that “on average, the mental health of low-income people was most harmed by hotter temperatures. Women, on average, were also harmed more than men.”
In an article for The Washington Post, Beth Simone Noveck highlights RiskMap, an open-source platform developed by researchers from MIT’s Urban Risk Lab that allows users to gather and access information about disaster areas. Noveck writes that “RiskMap is a paradigmatic example of collective intelligence.”
A new study co-authored by researchers at MIT finds that, “human activities are altering Earth's seasons in a way that is creating a greater contrast between summer and winter in much of North America, Europe and Eurasia,” reports Andrew Freedman for Axios.
NBC Mach’s Denise Chow discusses the upcoming hurricane season with Prof. Kerry Emanuel. “The sea level is going up, and it's almost certainly going to continue to go up,” explains Emanuel. “Even if the storms themselves don’t change, the surges are riding on an elevated sea level, and that makes them more dangerous.”
New research from visiting scientist Judah Cohen suggests that “severe winter weather in the United States is often tied to (relatively) high heat in the North Pole,” writes Eleanor Cummins for Popular Science. “If the Arctic is cold, that favors less severe winter in the eastern U.S.,”said Cohen. “When the Arctic is warm, it’s the opposite relationship.”
Matt Simon of Wired describes research led by visiting scientist Judah Cohen, which used the “Accumulated Winter Season Severity Index”, to reveal that warming in the arctic is associated with severe winter weather conditions. “[The researchers] looked at peaks in arctic temperatures and found that these anticipated severe weather by five days, which would suggest a link,” Simon writes.
Prof. Kerry Emanuel spoke about the work of former MIT professor Fred Sanders, who is credited with coining the term “bombogenesis." “Sanders described it kind of like a storm supercharged by a bomb…That term was quickly adopted in weather circles and, increasingly now, in popular parlance,” writes Edgar B. Herwick III for WGBH.
