Public interest for noctilucent clouds rose sharply in 2019 after record-setting outbreak across the northern hemisphere. The 2020 season is expected to start mid- to late-May or early June, but at the moment, it doesn't seem like 2020 will be a repeat of 2019….
A new study shows that natural hazards on Earth, specifically earthquakes and tsunamis, can create much more disturbances in the ionosphere than previously assumed. The researchers studied the catastrophic 2011 M9.0 Tohoku earthquake and tsunami in Japan, and found…
An analysis of satellite observations shows that ozone levels over the Arctic hit a record low for the month of March, NASA researchers reported on April 16, 2020. Ozone levels reached their lowest point on March 12 at 205 Dobson units. The depletion was caused by…
A huge ozone hole has opened this year over the Arctic. While ozone holes normally form in the Antarctic zone every year because winter temperatures drop to extremely low values, allowing high-altitude clouds to develop– the Arctic has more varying temperatures and…
A huge area of sustained ozone depletion has developed over the Arctic-Canadian region — too late for the winter season, too early for spring, and unusually strong for the northern hemisphere. The ozone layer is a natural layer of protective gas in the upper…
A massive sandstorm with winds up to 120 km/h (75 mph) hit the Canary Islands over the weekend and continued into Monday, February 24, 2020. The storm caused severe disruptions and exacerbated wildfires which forced about 2 000 residents to evacuate. The regional…
Air pressure over northern Norway dropped below 940 hPa on February 10, 2020, as Storm Ciara impacted much of northern Europe, leading to the cancelation of air traffic over the region for the first time ever due to low pressure. It also resulted in high water…
With 1 049.6 hPa registered at Heathrow Airport Sunday into Monday, January 19 to 20, 2020, London has set its new atmospheric pressure record — the highest since records began in 1692. The barometer reached 1 049.6 hPa overnight, breaking the previous record of 1…
A spectacular outbreak of rare polar stratospheric clouds (PDCs) was reported around the Arctic Circle, starting December 30, 2019. The display lasted nearly an hour and was commonly regarded as the brightest display that any of the locals have ever seen. The…
The air quality in Sydney, Australia continued to worsen on Tuesday, December 10, 2019, as roughly 100 bushfires burned in New South Wales (NSW) and strong north winds brought further smoke into the city. The haze was so thick in some areas that it was 11 times more…
